Upgrading --------- + [The following is a placeholder, to be revised asap] + - Upgrading to 5.1 is currently only supported from 4.0, 4.1 or 5.0. Clusters running earlier releases must first + upgrade to at least the latest 4.0 release. When a cluster is upgraded to 5.1 there is an additional step for + operators to perform. The upgrade is not considered complete until: + 1. All UP nodes are running 5.1 + 2. The Cluster Metadata Service (CMS) has been enabled + The first step is just a regular upgrade, there are no changes to external APIs, SSTable formats to consider. + Step 2 requires an operator to run a new nodetool subcommand, intializecms, on one node in the cluster. + - > nodetool initializecms + Doing so creates the CMS with the local node as its only member. The initializecms command cannot be executed until + step 1 is complete and all nodes are running 5.1 as migrating metadata management over to the new TCM system + requires all nodes to be in agreement over the current state of the cluster. Essentially this means agreement on + schema and topology. Once the upgrade has started, but before initializecms is run, metadata-changing operations are + not permitted and if attempted from an upgraded node will be rejected. + Prohibited operations include: + - schema changes + - node replacement + - bootstrap + - decommission + - move + - assasinate + For the time being there is no mechanism in place to prevent these operations being executed by a node still running + a previous version, though this is planned before release. Any automation which can trigger these operations should + be disabled for the cluster prior to starting the upgrade. + Should any of the prohibited operations be executed (i.e. on a node that is still running a pre-5.1 version) before + the CMS migration, nodes which are DOWN or which have been upgraded will not process the metadata changes. However, + nodes still UP and running the old version will. This will eventually cause the migration to fail, as the cluster + will not be in agreement. + - > nodetool initializecms + Got mismatching cluster metadatas from [/x.x.x.x:7000] aborting migration + See 'nodetool help' or 'nodetool help '. + If the initializecms command fails, it will indicate which nodes’ current metadata does not agree with the node + where the command was executed. To mitigate this situation, bring any mismatching nodes DOWN and rerun the + initializecms command with the additional —ignore flag. + - nodetool intializecms -ignore x.x.x.x + Once the command has run successfully the ignored nodes can be restarted but any metadata changes that they + accepted/and or applied whilst the cluster was in mixed mode will be lost. We plan to improve this before beta, but + in the meantime operators should ensure no schema or membership/ownership changes are performed during the upgrade. + Although the restrictions on metadata-changing operations will be removed as soon as the initial CMS migration is + complete, at that point the CMS will only contain a single member, which is not suitable for real clusters. To + modify the membership of the CMS a second nodetool subcommand, reconfigurecms, should be run. This command allows + the number of required number of CMS members to be specified for each datacenter. Consensus for metadata operations + by the CMS is obtained via Paxos, operating at SERIAL/QUORUM consistency, so the minimum safe size for the CMS is 3 + nodes. In multi-DC deployments, the CMS members may be distributed across DCs to ensure resilience in the case of a + DC outage. It is not recommended to make every node a member of the CMS. Redundancy is the primary concern here, not + locality or latency, so between 3 and 7 nodes per DC depending on the size of the cluster should be the goal. + Deploying to a fresh cluster is more straightforward. As the cluster comes up, at least one node will automatically + nominate itself as the first CMS node. A simple election mechanism ensures that only one node will be chosen if + multiple peers attempt to nominate themselves. As soon as the election is complete, metadata modifications are + supported. Typically, this takes only a few seconds and is likely to complete before all nodes are fully UP. Nodes + which come up during or after an election will learn of the elected first CMS node and direct metadata updates to + it. It is important to remember that at the completion of the election, the CMS still only comprises a single + member. Just as in the upgrade case, operators should add further members as soon as possible.

It describes a process of a node bringup into the existing TCM cluster. Each section will be prefixed by the header holding key classes that are used/described in the setion. + +## Startup: Discovery, Vote + +Boot process in TCM is very similar to the previously existing one, but is now split into several different classes rather than being mostly in `StorageService`. At first, `ClusterMetadataService` is initialized using `Startup#initialize`. Node determines its startup mode, which will be `Vote` in a usual case, which means that the node will initialize itself as a non-CMS node and will attempt to discover an existing CMS service or, failing that, participate in a vote to establish a new one with other discovered participants. If the seeds are configured correctly, the node is going to learn from the seed about existing CMS nodes, and will try contacting them to fetch the initial log. + +Node then continues startup, and eventually gets to `StorageService#initServer`, where it, among other things, gossips with CMS nodes to get a fresh view of the cluster for FD purposes, and then waits for Gossip to settle (again, for FD purposes). + +## Registration: ClusterMetadata, Transformation, RemoteProcessor + +Before joining the ring, the node has to register in order to obtain `NodeId`, which happens in `Register#maybeRegister`. Registration happens by committing a `Register` transformation using `ClusterMetadataService#commit` method. `Register` and other transformations are side-effect free functions mapping an instance of immutable `ClusterMetadata` to next `ClusterMetadata`. `ClusterMetadata` holds all information about cluster: directory of registered nodes, schema, node states and data ownership. + +Since the node executing register is not a CMS node, it is going to use a `RemoteProcessor` in order to perform this commit. `RemoteProcessor` is a simple RPC tool that serializes transformation and attempts to execute it by contacting CMS nodes and sending them `TCM_COMMIT_REQ`. + +## Commit Request: PaxosBackedProcessor, DistributedMetadataLogKeyspace, Retry + +When a CMS node receives a commit request, it deserializes and attempts to execute the transformation using `PaxosBackedProcessor`. Paxos backed processor stores an entire cluster metadata log in the `system_cluster_metadata.``distributed_metadata_log` table. It performs a simple CAS LWT that attempts to append a new entry to the log with an `Epoch` that is strictly consecutive to the last one. `Epoch` is a monotonically incrementing counter of `ClusterMetadata` versions. + +Both remote and paxos-backed processors are using `Retry` class for managing retries. Remote processor sets a deadline for its retries using `tcm_await_timeout`. CMS-local processor permits itself to use at most `tcm_rpc_timeout` for its attempts to retry. + +`PaxosBackedProcessor` then attempts to execute `Transformation`. Result of the execution can be either `Success` or `Reject`. `Reject`s are not persisted in the log, and are linearized using a read that confirms that transformation was executed against the highest epoch. Examples of `Reject`s are validation errors, exceptions encountered while attempting to execute transformation, etc. For example, `Register` would return a rejection if a node with the same IP address already exists in the registry. + +## Commit Response: Entry, LocalLog + +After `PaxosBackedProcessor` suceeds with committing the entry to the distributed log, it broadcasts the commit result that contains `Entry` holding newly appended transformation to the rest of the cluster using `Replicator` (which simply iterates all nodes in the directory, informing them about the new epoch). This operation does not need to be reliable and has no retries. In other words, if a node was down during CMS attempt to replicate entries to it, it will inevitably learn about the new epoch later when it comes back alive. + +Along with committed `Entry`, the response from CMS to the peer which submitted it also contains all entries that will allow the node that has initiated the commit to fully catch up to the epoch enacted by the committed transformation. + +When `RemoteProcessor` receives a response from CMS node, it appends all received entries to the `LocalLog`. `LocalLog` processes the backlog of pending entries and enacts a new epoch by constructing new `ClusterMetadata`. + +## Bootstrap: InProgressSequence, PrepareJoin, BootstrapAndJoin + +At that point, the node is ready to start the process of joining the ring. It begins in `Startup#startup`. `Startup#getInitialTransformation` determines that the node should start regular bootstrap process (as opposed to replace), and the node proceeds with commit of `PrepareJoin` transformation. During `PrepareJoin`, `ClusterMetadata` is changed in the following ways: + +* Ranges that will be affected by the bootstrap of the node are locked (see `LockedRanges`) + * If computed locked ranges intersect with ranges that were locked before this transformation got executed, `PrepareJoin` is rejected. +* `InProgressSequence`, holding the three transformations (`PrepareJoin`, `MinJoin` `FinishJoin`), is computed and added to `InProgressSequences` map. + * If any in-progress sequences associated with the current node are present, `PrepareJoin` is rejected. +* `AffectedRanges`, ranges whose placements are going to be changed while executing this sequence, are computed and returned as a part of commit success message. + +`InProgressSequence` is then executed step-by step. All local operations that the node has to perform between executing these steps are implemented as a part of the in-progress sequence (see `BootstrapAndJoin#executeNext`). We make *no assumptions* about liveness of the node between execution of in-progress sequence steps. For example, the node may crash after executing `PrepareJoin` but before it updates tokens in the local keyspace. So the only assumption we make is that `SystemKeyspace.updateLocalTokens` has to be called *before* `StartJoin` is committed. Similarly, owned data has to be streamed towards the node *before* it becomes a part of a read quorum, so even if the node crashes or is restarted an arbitrary number of times during streaming. + +In order to ensure quorum consistency, before executing each next step, the node has to await on the `ProgressBarrier`. CEP-21 contains a detailed explanation about why progress barriers are necessary. For the purpose of this document, it suffices to say that majority of owners of the `AffectedRanges` have to learn about the epoch enacting the previous step before each next step can be executed. This is done in order to preserve replication factor for eventually consistent queries. + +Upon executing all steps in the progress sequence, ranges are unlocked, and sequence itself is removed from `ClusterMetadata`. + + +## Querying: CoordinatorBehindException, FetchPeerLog, FetchCMSLog + +As the node starts participating in reads and writes, it may happen that its view of the ring or schema becomes divergent from other nodes. TCM makes best effort to minimize the time window of this happening, but in a distributed system at least some delay is inevitable. TCM solves this problem by including the highest `Epoch` known by the node in every request that the node coordinates, and in every response to the coordinator when serving as a replica. + +Replicas can check the schema and ring consistency of the *current* request by comparing the `Epoch` that coordinator has with the epoch when schema was last modified, and when the placements for the given range were last modified. If it happens that the replica knows that coordinator couldn’t have known about either schema, or the ring, it will throw `CoordinatorBehindException`. In all other cases (i.e. when either coordinator, or the replica are aware of the higher `Epoch`, but existence of this epoch does not influence consistency or outcome of the given query), lagging participant will issue an asynchonous `TCM_FETCH_PEER_LOG_REQ` and attempt to catch up from the peer. Failing that, it will attempt to catch up from the CMS node using `TCM_FETCH_CMS_LOG_REQ`. + +After coordinator has collected enough responses, it compares its `Epoch` with the `Epoch` that was used to construct the `ReplicaPlan` for the query it is coordinating. If epochs are different, it checks if collected replica responses still correspond to the consistency level query was executed at. + diff --git a/src/java/org/apache/cassandra/tcm/TransactionalClusterMetadata.md b/src/java/org/apache/cassandra/tcm/TransactionalClusterMetadata.md new file mode 100644 index 0000000000..75fada86ae --- /dev/null +++ b/src/java/org/apache/cassandra/tcm/TransactionalClusterMetadata.md @@ -0,0 +1,77 @@ + + +# Transactional Cluster Metadata (TCM) + +### More Detail + +Further detail on the motivation, design, constraints and guarantees of TCM can be found in the Cassandra Enhancement Proposal document at https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-21%3A+Transactional+Cluster+Metadata + +Lower level implementation details regarding certain areas of the codebase can be found in-tree in TCM_implementation.md + +## ClusterMetadata + +`ClusterMetadata` is the immutable data object representing metadata about the state of the cluster. + +## Cluster Metadata Service +A subset of nodes in the cluster act as members of the Cluster Metadata Service (CMS) to maintain a log of events which modify cluster wide metadata. Membership of the CMS is flexible and dynamic and is updated when any of the existing members are decommissioned or replaced. + +Members of the CMS are responsible for linearizing insertion of entries into the metadata change log. An entry contains a transformation to be applied to ClusterMetadata and a monotonically increasing counter, or epoch. Each event committed to the log by the CMS implies a new epoch and as such, an epoch represents a specific point in the linearized history of cluster metadata. + + Clients of the CMS submit metadata change events and the CMS node receiving it determines whether that event should be executed or rejected based on the current metadata state. The CMS enforces a serial order (initially using Paxos LWTs to insert into a distributed log table) for accepted events and proactively disseminates them to the rest of the cluster. + +Independently, each node in the cluster applies the replicated transformations in strict order to produce a consistent view of metadata. After doing so, the transformed `ClusterMetadata` is atomically published on the node so that the most current metadata is always available. Code consuming metadata never witnesses partial updates to `ClusterMetadata`, and each version is uniquely identifiable by its epoch. + +## Schema + +`DistributedSchema` is a component of `ClusterMetadata` and all DDL updates are applied by the CMS inserting a log entry containing a schema transformation. As the log entries are disseminated around the cluster, each peer applies the transformation to its local `ClusterMetadata`, enacting the schema change. This entails some changes to the way the database objects represented in schema are intialised locally (db objects refers to classes like `Keyspace`, `ColumnFamilyStore`, etc). + +## Cluster Membership + +The `Directory` component of `ClusterMetadata` manages member identity, state, location and addressing. This duplicates many of the functions previously performed by `TokenMetadata`, `Topology` et al but with updates performed in deterministic order via the global log. + +## Data Placement + +`DataPlacements` provide a mapping from (keyspace, token range) tuples to sets of replicas. There are several such mappings in a cluster, one for each distinct set of `ReplicationParams` belonging to keyspaces in the schema. Where previously these mappings would be calculated on demand as topology modifications were discovered via gossip, these are now statically constructed for/from a given `ClusterMetadata` version. + +## Operations + +Performing operations such as shrink, expand, node replacement etc, do not simply modify metadata so atomic updates to cluster metadata are not in themselves sufficient for performing these safely. Streaming transfer of data between nodes must also occur and this must happen concurrently with reads and writes. Replication factors for writes must be temporarily expanded during range movements, what was previously provided by the concept of `PendingRanges`. + +With TCM, these operations are performed in coordinated phases, planned in advance and properly linearized using the global log. For instance, to join an new node, the full set of phased range movements required is calculated to generate an actionable plan which is then stored in `InProgressSequences`, another component of `ClusterMetadata`. + +Concurrent operations are permitted as long as they only affect disjoint token ranges, ensuring that concurrent range movements remain safe and cluster invariants are preserved at all times, including in the case of the failure to complete any operation (i.e. failed or aborted bootstrap). + +## Read/Write Consistency + +During a read or write, the coordinator constructs a replica plan based on the cluster metadata that is known to it at the time. The `Mutation` or`ReadCommand` messages that the coordinator sends to those replicas include the epochs which identify the most recent changes to either `DataPlacements` or `TableMetadata` which may have a material effect on the execution of the message payload. This allows replicas and coordinators to detect divergence between their respective metadata and take action accordingly. Coordinators also re-check `DataPlacements` after collecting replica responses, before returning to the client. If these have changed while the request was in flight, the coordinator can then verify whether received responses meet the desired consistency given the new topology. + +## Recovering Missing Log Entries + +A node may detect that it is missing some entries from the metadata log, either by receiving an update from the CMS which is non-consecutive with its current metadata epoch or during an exchange of messages with a peer. Catching up can be done simply by requesting the sequence of log entries with a greater epoch than any previously seen by the node. As the log is immutable and totally ordered, this request can be made to any peer as the results must be consistent, but not exhaustive. Any peers themselves may be lagging behind the "true" tail of the log, but this is perfectly acceptable, as it is impossible to propagate changes to all participants simultaneously, and we achieve correctness by means other than synchrony. + +Nodes provide each other with missing log entries in the form of a `LogState`, which comprises an optional snapshot of `ClusterMetadata` at a given epoch, plus a list of individual log entries (a `Replication` object) to apply on top of the snapshot (if present). When receiving a `LogState`, the node can use the snapshot to effectively skip ahead to a precise point in the linearized history without requiring every intermediate transformation individually. To do this, it constructs a synthetic log entry containing a `ForceSnapshot` transformation which it inserts at the head of its local buffer of pending log entries. The log consumer then applies this transformation, producing a new `ClusterMetadata` (the exact one contained in the `LogState`) and publishing it as it would the result of any other transformation. + +## Upgrading and Transitioning to TCM +Following an upgrade, nodes in an existing cluster will enter a minimal modification mode. In this state, the set of allowed cluster metadata modifications is constrained to include only the addition, removal and replacement of nodes, to allow failed hosts to be replaced during the +upgrade. In this mode the CMS has no members and each peer maintains its own `ClusterMetadata` instance independently. This metadata is intitialised at startup from system tables and gossip is used to propagate the permitted subset of metadata changes. + +When the operator is ready, one node is chosen for promotion to the initial CMS, which is done manually via nodetool `initializecms`. At this point, the candidate node will propose itself as the initial CMS and attempt to gain consensus from the rest of the cluster. If successful, it verifies that all peers have an identical view of cluster metadata and initialises the distributed log with a snapshot of that metadata. + +Once this process is complete all future cluster metadata updates are performed via the CMS using the global log and reverting to the previous method of metadata management is not supported. Further members can and should be added to the CMS using nodetool's `reconfigurecms` command. + diff --git a/src/java/org/apache/cassandra/tcm/Transformation.java b/src/java/org/apache/cassandra/tcm/Transformation.java new file mode 100644 index 0000000000..df15598b4d --- /dev/null +++ b/src/java/org/apache/cassandra/tcm/Transformation.java @@ -0,0 +1,320 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.

While range + * movements/bootstraps/decommissions are in-flight, this will not be the case as the read and write replica + * sets will diverge while nodes are acquiring/relinquishing ranges. Although there may always be such operations + * ongoing, this is technically a temporary state. + * + * Because of this, when calculating the steps to transition between the current state and a proposed new state, + * we work from the associated TokenMaps, the assumption being that eventually both the read and write placements + * will converge and will, at that point, reflect those TokenMaps. + * This means that the starting point of each transition is the intended end state of the preceding transitions. + * + * To do this calculation, we create a canonical DataPlacement from the current TokenMap and split it according + * to the proposed tokens. As we iterate through and split the existing ranges, we construct a new DataPlacement for + * each currently defined. There is no movement of data between the initial and new placements, only splitting of + * existing ranges, so we can simply copy the replica groups from the old ranges to the new. + * e.g.: + * We start with a portion of the ring containing tokens 100, 200 assigned to nodes A & B respectively.
