* Make sure we wait for all scheduled tasks to complete before throwing ↵Dan Engelbrecht2024-02-281-0/+4
| | | | | exceptions further (#662) Bugfix: We must not throw exceptions to calling function until all async work we spawned has returned

* Fix crash bug when trying to inspect non-open block file in GC (#614)Dan Engelbrecht2023-12-181-0/+1

* improved scrubbing of oplogs and filecas (#596)Stefan Boberg2023-12-112-1/+8
| | | | | | - Improvement: Scrub command now validates compressed buffer hashes in filecas storage (used for large chunks) - Improvement: Added --dry, --no-gc and --no-cas options to zen scrub command - Improvement: Implemented oplog scrubbing (previously was a no-op) - Improvement: Implemented support for running scrubbint at startup with --scrub=<options>
* reserve vectors in gcv2 upfront / load factor for robin_map (#582)Dan Engelbrecht2023-12-042-16/+26
| | | | | * 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
* use 32 bit offset and size in BlockStoreLocation (#581)Dan Engelbrecht2023-12-011-13/+13
| | | - Improvement: Reduce memory usage in GC and diskbucket flush
* add separate PreCache step for GcReferenceChecker (#578)Dan Engelbrecht2023-12-012-0/+6
| | | | | | - Improvement: GCv2: Use separate PreCache step to improve concurrency when checking references - Improvement: GCv2: Improved verbose logging - Improvement: GCv2: Sort chunks to read by block/offset when finding references - Improvement: GCv2: Exit as soon as no more unreferenced items are left
* optimized index snapshot reading/writing (#561)Stefan Boberg2023-11-271-1/+10
| | | | | the previous implementation of in-memory index snapshots serialise data to memory before writing to disk and vice versa when reading. This leads to some memory spikes which end up pushing useful data out of system cache and also cause stalls on I/O operations. this change moves more code to a streaming serialisation approach which scales better from a memory usage perspective and also performs much better
* gc stop command (#569)v0.2.36-pre2Dan Engelbrecht2023-11-271-0/+2
| | | | | - Feature: New endpoint `/admin/gc-stop` to cancel a running garbage collect operation - Feature: Added `zen gc-stop` command to cancel a running garbage collect operation - Bugfix: GCv2 - make sure to discover all projects and oplogs before checking for expired data
* Add GC Cancel/Stop (#568)Dan Engelbrecht2023-11-242-5/+16
| | | | - 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.

| | | | | | | | | | | - 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 Engelbrecht2023-11-212-49/+57
| | | | | - 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 history log (#519)Dan Engelbrecht2023-11-131-0/+7
| | | | | - Feature: Writes a `gc.log` with settings and detailed result after each GC execution (version 2 only) - Break out file name rotate to allow access for gclog - CompactBinaryToJson(MemoryView Data, StringBuilderBase& InBuilder)
* spdlog implementation hiding (#498)Stefan Boberg2023-11-061-19/+16
| | | | | | | | | this change aims to hide logging internals from client code, in order to make it easier to extend and take more control over the logging process in the future. As a bonus side effect, the generated code is much tighter (net delta around 2.5% on the resulting executable which includes lots of thirdparty code) and should take less time to compile and link. Client usage via macros is pretty much unchanged. The main exposure client code had to spdlog internals before was the use of custom loggers per subsystem, where it would be common to have `spdlog::logger` references to keep a reference to a logger within a class. This is now replaced by `zen::LoggerRef` which currently simply encapsulates an actual `spdlog::logger` instance, but this is intended to be an implementation detail which will change in the future. The way the change works is that we now handle any formatting of log messages in the zencore logging subsystem instead of relying on `spdlog` to manage this. We use the `fmt` library to do the formatting which means the client usage is identical to using `spdlog`. The formatted message is then forwarded onto any sinks etc which are still implememted via `spdlog`.

* individual gc stats (#506)Dan Engelbrecht2023-10-301-21/+69

* Remove any unreferenced blocks in block store on open (#492)Dan Engelbrecht2023-10-231-3/+2
| | | * Remove any unreferenced blocks in block store on open
* Don't prune block locations due to missing blocks a startup (#487)Dan Engelbrecht2023-10-201-5/+7
| | | | | | * Don't prune block locations due to missing blocks a startup This makes the behaviour consistent with FileCas - you can have an index that is not fully backed by data. Asking for a location that is not backed by data results in getting an empty result back Also, don't try to GC blocks that are unknown to the block store at the time of snapshot (to avoid removing data that comes in after GatherReferences in GC)
