Poyzan	3f0f8fa5f5	[bloom-compactor] Move meta.json creation at the end of compaction cycle (#11234 ) What this PR does / why we need it: This is a follow up from https://github.com/grafana/loki/pull/11115 Instead of a creating a meta file per bloom creation, create a meta file per compaction cycle. Which issue(s) this PR fixes: Fixes #<issue number> Special notes for your reviewer:	2 years ago

Salva Corts	4248825ad2	Bloom-compactor Sharding (#11154 ) What this PR does / why we need it: This PR adds tenant and fingerprint (FP) sharding to bloom compactors. Note that the bloom-compactor doesn't yet perform any compaction, but iterates through all tables, tenants, and series checking if the compactor owns the tenant and the series (by the series FP). Actual compaction will be implemented with https://github.com/grafana/loki/pull/11115. A new structure `Job` is added which will carry around all the context for a compaction job such as the tenant ID, the table name, and the series FP. The sharding strategy has two methods: - `OwnsTenant(tenant string)`: Checks if the compactor shard owns the tenant. - `OwnsJob(job Job)`: Checks (again) if the compactor owns the job's tenant. Then, it checks if the compactor owns the job's fingerprint by looking inside the tenant subring. We add a new per-tenant limit: `bloom_compactor_shard_size`. If it's 0, the tenant can use all compactors (i.e. `OwnsTenant` will always return `true`), otherwise, only `bloom_compactor_shard_size` out of the total number of compactors will own the tenant. A given job's FP will be owned by exactly one compactor within the tenant shard. Special notes for your reviewer: - Added a bunch of metrics in `metrics.go` - Added a test for the sharding strategy	2 years ago
Poyzan	cc6f0eca98	Return checksum from BuildFrom function (#11178 ) What this PR does / why we need it: Follow up from https://github.com/grafana/loki/pull/11115 We want to know the checksum of the bloom blocks before uploading them to storage. Instead of opening the file and reading it, this PR returns the checksum from where it's created.	2 years ago
Poyzan	fa378ac0ec	Add first step for creating a single bloom from series (#11115 ) What this PR does / why we need it: This is the first step to create a bloom from a series. The logic to get tenants and tables is a temporary hack and will be replaced by the ring logic in https://github.com/grafana/loki/pull/11154 Which issue(s) this PR fixes: Fixes #<issue number> Special notes for your reviewer: It does not handle appending multiple blooms into blocks. It does not handle creating and uploading of meta files.

Salva Corts	89829065e7	Use lazy bloom filter (#10896 ) What this PR does / why we need it: When querying bloom filters, use lazy decoders from https://github.com/owen-d/BoomFilters/pull/1 so we don't make a copy of bloom filters.	2 years ago
Poyzan	0832256d7b	Add basic structure of bloom compactor (#10748 ) This pull request adds the basic structure for the new bloom compactor component. - Adds new `bloom-compactor` target that runs with with multiple instances joined by a ring - Adds boilerplate functions to index blooms and compact blocks The main goal of this PR is to provide a basic functionality on which future smaller PRs can build upon. Since the code path is completely separate in a new component, it is not used anywhere at the moment.	2 years ago
