* Miscellaneous minor LLM fixes (#268)v5.5.17-pre0Stefan Boberg2024-12-171-0/+2
| | | | | | | With this change, LLM tags are assigned using the name,parent tuple rather than just by name only. This allows tag hierarchies like `cache/store` and `project/store` which would previously get collapsed into the first pair seen when registering the `store` tag. This PR also adds some more LLM tag annotations to more accurately associate memory allocations with subsystems In addition, this PR also tweaks the frequency of timer marker events to increase the resolution in Insights and avoid some cases of Insights deciding that marker events are too far apart since we don't allocate as frequently as UE tends to.

| | | | | | - Improvement: Batch fetch record attachments when appropriate - Improvement: Reduce memory buffer allocation in BlockStore::IterateBlock - Improvement: Tweaked BlockStore::IterateBlock logic when to use threaded work (at least 4 chunks requested) - Bugfix: CasContainerStrategy::IterateChunks could give wrong payload/index when requesting 1 or 2 chunks

* oplog prep gc fix (#216)Dan Engelbrecht2024-11-152-28/+48
| | | | | | - Added option gc-validation to zenserver that does a check for missing references in all oplog post full GC. Enabled by default. - Feature: Added option gc-validation to zen gc command to control reference validation. Enabled by default. - Added more details in post GC log. - Fixed race condition in oplog writes which could cause used attachments to be incorrectly removed by GC
* memory leak fix (GetBatchHandle) (#215)Stefan Boberg2024-11-081-0/+4
| | | This fixes a memory leak which would cause stale handles to accumulate until process shutdown. Each cache get operation would therefore leak some memory.

| | | - Feature: Added options --bucketsize and --bucketsizes to zen cache-info to get data sizes in cache buckets and attachments

* optimize gc reference sort (#179)Dan Engelbrecht2024-10-011-4/+3
| | | | | - Do a single call to mempcy when fetching attachments from the meta store in GC - Use small lambda when calling std::sort in FilterReferences (enables inlining of the comparision function) - Use a single function for < and == comparision in KeepUnusedReferences

| | | | | | | - Improvement: Faster memcache trimming - Reduce calculations while holding bucket lock for memcache trim analysis to reduce contention - When trimming memcache, evict 25% more than required to reduce frequency of trimming - When trimming memcache, don't repack memcache data vector, defer that to regular garbage collection - When trimming memcache, deallocate memcache buffers when not holding exclusive lock in bucket
* Add `gc-attachment-passes` option to zenserver (#167)Dan Engelbrecht2024-09-252-3/+3
| | | | | Added option `gc-attachment-passes` to zenserver Cleaned up GCv2 start and stop logs and added identifier to easily find matching start and end of a GC pass in log file Fixed project store not properly sorting references found during lock phase
