* use direct file access for large file hash (#63)Dan Engelbrecht2024-04-261-1/+1
| | | - Improvement: Refactor `IoHash::HashBuffer` and `BLAKE3::HashBuffer` to not use memory mapped files. Performs better and saves ~10% of oplog export time on CI
* iterate cas chunks (#59)Dan Engelbrecht2024-04-241-0/+31
| | | - Improvement: Reworked GetChunkInfos in oplog store to reduce disk thrashing and improve performance

| | | | | exceptions further (#662) Bugfix: We must not throw exceptions to calling function until all async work we spawned has returned

| | | | | * reserve vectors in gcv2 upfront * set max load factor for robin_map indexes to reduce memory usage * set min load factor for robin_map indexes to allow them to shrink

| | | | | | - Improvement: Added more trace scopes for GCv2 - Bugfix: Make sure we can override flags to "false" when running `zen gc` commmand - `smallobjects`, `skipcid`, `skipdelete`, `verbose`

* Add GC Cancel/Stop (#568)Dan Engelbrecht2023-11-241-2/+20
| | | | - GcScheduler will now cancel any running GC when it shuts down. - Old GC is rather limited in *when* it reacts to cancel of GC. GCv2 is more responsive.
* add command line options for compact block threshold and gc verbose (#557)Dan Engelbrecht2023-11-211-1/+1
| | | | | | | | | | | - Feature: Added new options to zenserver for GC V2 - `--gc-compactblock-threshold` GCV2 - how much of a compact block should be used to skip compacting the block, default is 90% - `--gc-verbose` GCV2 - enable more verbose output when running a GC pass - Feature: Added new options to `zen gc` command for GC V2 - `--compactblockthreshold` GCV2 - how much of a compact block should be used to skip compacting the block, default is 90% - `--verbose` GCV2 - enable more verbose output when running a GC pass - Feature: Added new parameters for endpoint `admin/gc` (PUT) - `compactblockthreshold` GCV2 - how much of a compact block should be used to skip compacting the block, default is 90% - `verbose` GCV2 - enable more verbose output when running a GC pass
* compact separate for gc referencer (#533)Dan Engelbrecht2023-11-211-52/+61
| | | | | - Refactor GCV2 so GcReferencer::RemoveExpiredData returns a store compactor, moving out the actual disk work from deleting items in the index. - Refactor GCV2 GcResult to reuse GcCompactStoreStats and GcStats - Make Compacting of stores non-parallell to not eat all the disk I/O when running GC
* gc v2 tests (#512)Dan Engelbrecht2023-11-061-1/+1
| | | | | | | | | | * set MaxBlockCount at init * properly calculate total size * basic blockstore compact blocks test * correct detection of block swap * Use one implementation for CreateRandomBlob * reduce some data sets to increase speed of tests * reduce test time * rename BlockStoreCompactState::AddBlock -> BlockStoreCompactState::IncludeBlock
* individual gc stats (#506)Dan Engelbrecht2023-10-301-36/+63
| | | | | - Feature: New parameter for endpoint `admin/gc` (GET) `details=true` which gives details stats on GC operation when using GC V2 - Feature: New options for zen command `gc-status` - `--details` that enables the detailed output from the last GC operation when using GC V2
* New GC implementation (#459)Dan Engelbrecht2023-10-301-1/+166
| | | - Feature: New garbage collection implementation, still in evaluation mode. Enabled by `--gc-v2` command line option
* added missing includes (#504)Stefan Boberg2023-10-271-0/+4
| | | | | this change adds some includes to files which "inherit" includes from elsewhere this was exposed on another branch when removing some heavy dependencies from central headers

* Handle OOM and OOD more gracefully to not spam Sentry with error reports (#434)Dan Engelbrecht2023-10-021-9/+25
| | | | | | - Improvement: Catch Out Of Memory and Out Of Disk exceptions and report back to reqeuster without reporting an error to Sentry - Improvement: If creating bucket fails when storing and item in the structured cache, log a warning and propagate error to requester without reporting an error to Sentry - Improvement: Make an explicit flush of the active block written to in blockstore flush - Improvement: Make sure cache and cas MakeIndexSnapshot does not throw exception on failure which would cause and abnormal termniation at exit

| | | | | Scrub -> ScrubStorage Trigger -> TriggerGc (to make relationship to TriggerScrub clearer)
* Remove ATL header usage (#306)Stefan Boberg2023-05-151-4/+4
| | | ATL has been used here and there as a convenience. Given that this is a legacy component and not always something which gets installed along with the compiler we hereby remove the dependency altogether in favour of our own simple wrappers
