* Encryption data at-rest db-config
Description
diff-1: Handle 'force' updates to encryption_at_rest db-config
Major changes proposed:
1. Introduce 'encryption_data_at_rest_mode" 'configure new'
option to enable Encryption data at-rest. The feature is disabled
by default.
2. The configuration is meant to be set at the time of database
creation, addition checks will be done to avoid updating the config
in subsequent PR.
3. DatabaseConfiguration validity check to account for "tenant_mode"
set to `required` if Encryption data at-rest is selected given
EncryptionDomain matches Tenant boundaries.
Testing
devCorrectness - 100K
* throttle the cluster when blob workers fall behind
* do not throttle on blob workers if they are not enabled
* remove an unnecessary actor
* fixed a compile error
* fetch blob worker metrics at the same interval as the rate is updated, avoid fetching the complete blob worker list too frequently
* fixed another compilation bug
* added a 5 second delay before bw throttling to prevent false positives caused by the 100e6 version jump during recovery. Lower the throttling thresholds to react much quicker to bw lag.
* fixed a number of problems
* changed the minBlobVersionRequest to look at storage server versions since this will be a lot more efficient
* fix: do not let desired go backwards
* fix: track the version of notAtLatest changefeeds for throttling
* ratekeeper now throttled blob workers by estimating the transaction per second throughput of the blob workers
* added metrics for blob worker change feeds
* added a knob to disable bw throttling
* fixed the transaction options in blob manager
* add storagemetadata
* add StorageWiggler;
* fix serverMetadataKey bug
* add metadata tracker in storage tracker
* finish StorageWiggler
* update next storage ID
* change pid to server id
* write metadata when seed SS
* add status json fields
* remove pid based ppw iteration
* fix time expression
* fix tss metadata nonexistence; fix transaction retry when retrieving metadata
* fix checkMetadata bug when store type is wrong
* fix remove storage status json
* format code
* refactor updateNextWigglingStoragePID
* seperate storage metadata tracker and store type tracker
* rename pid
* wiggler stats
* fix completion between waitServerListChange and storageRecruiter
* solve review comments
* rename system key
* fix database lock timeout by adding lock_aware
* format code
* status json
* resolve code format/naming comments
* delete expireNow; change PerpetualStorageWiggleID's value to KeyBackedObjectMap<UID, StorageWiggleValue>
* fix omit start rount
* format code
* status json reset
* solve status json format
* improve status json latency; replace binarywriter/reader to objectwriter/reader; refactor storagewigglerstats transactions
* status timestamp
Major changes includes:
1. Add a new FDB role responsible- EncyrptKeyProxy. The role is
responsible to expose APIs to fetch encyrption keys interacting
with external Encryption KeyManager interface.
2. The process is a FDB singleton process following similar recruitment
rules as other singleton processes in the system.
3. Code to recruit the worker process; given the encryption keys are
needed during recovery (decode TLog records), for now the process
is co-located in same datacenter as ClusterController.
4. Skeleton process actor code; more functionality will be added in
subsequent PRs.
NOTE: The code is protected under a SERVER_KNOB with the default
value as 'false' for now.
* Revert "Revert "Refactor: ClusterController driving cluster-recovery state machine""
Major changes includes:
1. Re-revert Sequencer refactor commits listed below (in listed order):
1.a. This reverts commit bb17e194d9.
1.b. This reverts commit d174bb2e06.
1.c. This reverts commit 30b05b469c.
2. Update Status.actor to track ClusterController interface to track
recovery status.
3. Introduce a ServerKnob to define "cluster recovery trace event"
prefix; for now keeping it as "Master", however, it should allow
smooth transition to "Cluster" prefix as it seems more appropriate.
