* Remove API 720 guards for tenants (experimental feature) and the cluster ID special keys (no need to guard)
* Enable the relaxed special key access in transactions that need to use special key-space APIs introduced in 7.2
* ApiTester: enable access to database instances in workloads
* ApiTester: Inject database create errors
* Fix getClusterProtocol and database shared object initialization in case of database create errors
* Check deferred error in all Thread-Safe API calls returning a future
* ApiTester: disable injection of database create errors for tests with old versions
* flow: add ApiVersion to replace hard coding api version
Instead of hard coding api value, let's rely on feature versions akin to
ProtocolVersion.
* ApiVersion: remove use of -1 for latest and use LATEST_VERSION
* do not count recently created change feeds for throttling
* fix: blocked assignments were not decremented when force purging
* fix: created needs to be updated when the changefeed is reset
* added asserts to detect if ratekeeper is throttled on blob workers
* Adding BlobRange test
* refactored blobrange test to use new db functions, and fixed several bugs
* bug fixes for blob manager and verifyBlobRange
* More range unaligned fixes
* cleaning up test and disabling tests that don't work yet for now
* removing overzealous assert in blob manager
* more fixes for overzealous assert
* cleanup and renaming test
* adding chaos to blob ranges test
* Throttle the cluster if the blob manager cannot assign ranges
* fixed a number of different bugs which caused ratekeeper to throttle to zero because of blob worker lag
* fix: do not mark an assignment as block if it is cancelled
* remove asserts to merge bug fixes
* fix formatting
* restored old control flow to storage updater
* storage updater did not throw errors
* disable buggify to see if it fixes CI
* Cleaned up BlobGranule TODO + FIXMEs and addressed some
* popping feed at correct version
* blob worker taking over a granule will pop from where previous worker left off
* addressed fixme of blob worker not re-snapshotting from old change feed
* formatting
* more change feed popped fixes after pop updates
* Getting rid of change feed parallelism lock since it can cause deadlocks in fetching, and relying on full fetch lock
* New blob worker metric and fixing old one
* server-side popped checking still doesn't work because of pops at non-mutation versions
* format
* Add the verify option for \xff\xff/worker_interfaces
* Remove unused code
* update documentations
* update documentations
* solve comments from review
* update some of the comments to be more clear
* 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
Currently GRV is reporting proxy_memory_limit_exceeded error which has
error message claiming Commit proxy failing. This split should remove
such confusion.
* Granule purge cannot delete history entry for fully deleting granule until all children are completely done splitting
* Several purging fixes related to granule history
* Fixed typo in refactor
* fixing memory model for purgeRange
* formatting
* weakening granule purge test for now
* cleanup
* First version of force purging granules
* fixing issue in BW range assignment reporting
* Fixing incorrect assert with force purging
* Error handling when checking force purged state
* fixed force purging and recover/reassign range races and check
* Handling force purge + boundary change race
* more places to check for force purged status
* fixed manager restart in the middle of force purge bug
* fixing same-BM purge and assignment races in all cases
* weakening orphaned granule history check a bit because of difficult to solve races
* fixing txn options on retry
* loading force purged ranges at start to avoid resuming a merge that is being force purged
* cleanup
* Enabling purging in granule tests, and adding check for leaked change feeds in force purge
* formatting
* missed parameter in merge conflicts
* Fixing leaked change feed race with merge and force purge
* adding change feed cleanup when new blob manager recovers in-progress merge that raced with force purge
* added forcepurge fdbcli command
* fixing another actor cancelled callback issue in change feed stream
* remove wait for on move, to ensure stream can't read from a shard the SS no longer owns
* fixing key alignment after downsampling split
* Fixing out-of-date granule reporting itself as a merge candidate
* fix formatting
* Enable configuring the next future protocol version as the current protocol version in FDB client, fdbserver, and fdbcli
* Auto format python files used in upgrade tests
* Add a test for upgrading to a future FDB version
* Emphasize that the options for using future protocol version are intended for test purposes only
* Make the global variable for current protocol version visible only locally
* Refactirng to avoid using currentProtocolVersion() in static intialization
* Update go bindings
* Track when version not found in version vector.
* Respond to comments
* include vv in event
* Respond to review comments.
* Fix bug where we logged too many lines
Dummy transaction commits are made when earlier transaction returned
commit_unknown_result or request_maybe_delivered, to affirm the status
of earlier transaction. Without tenant-awareness, these transactions
will fail due to lack of authorization in case of untrusted clients.
