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

Christian Haudum	3f28e6362d	Fix flaky bloomgateway test case (#11001 ) The order of active users is non-deterministic, so we need to check for matching elements, rather than for equal slice. Failed test run: https://drone.grafana.net/grafana/loki/29579/3/6 Passed test run: https://drone.grafana.net/grafana/loki/29577/3/6 Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago
Dylan Guedes	9d9b05ad40	Bloomgateway: Use RUnlock to unlock RLock instead (#10984 ) What this PR does / why we need it: Change `Len()` method to use `RUnlock()` instead, since it was locked using `RLock()`.	2 years ago
Christian Haudum	27411cff08	Introduce worker queue in bloom gateway (#10976 ) Instead of calling the bloom store directly on each and every request to filter chunk refs based on the given filters, we want to queue requests in per-tenant queues and process batches of requests that can be multiplexed to avoid excessive seeking in the bloom block queriers when checking chunk matches. This PR re-uses the request queue implementation used in the query scheduler. To do so, it moves the queue related code from the scheduler into a separate package `pkg/queue` and renames occurrences of "querier" to "consumer" to be more generic. The bloom gateway instantiates the request queue when starting the service. The gRPC method `FilterChunkRefs` then enqueues incoming requests to that queue. Special notes for your reviewer: For testing purposes, this PR also contains a dummy implementation of the workers. The worker implementation - which includes multiplexing of multiple tasks - is subject to a separate PR. --------- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago
Christian Haudum	2abb472e7e	Unify ring managers across components (#10931 ) What this PR does / why we need it: This PR creates a re-usable `RingManager` implementation that is then used by * Query Scheduler ring * Index Gateway ring * Bloom Gateway ring * Bloom Compactor ring Which issue(s) this PR fixes: Every component had its own implementation of the ring manager which only really differed in the log messages containing the component name. --------- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	2 years ago
Christian Haudum	d84026cab6	Adjust bloom gateway request structure (#10926 ) What this PR does / why we need it: Since we already group chunkRefs by fingerprint on the client side to determine the correct bloom gateway to send the request to, we can keep the grouping for the gRPC request. This will not only optimize the request size, but also helps to reduce complexity of querying blooms on the bloom gateway itself. There is still conversion between `[]logproto.ShortRef` and `v1.ChunkRefs` required, which could be removed by sending `v1.ChunkRefs` over the wire.

Christian Haudum	b49b3ce6e1	Add basic structure of bloom gateways (#10782 ) ### Summary This pull requests adds the basic structure for the new bloom gateway component. - Adds new `bloom-gateway` target that runs with multiple instances joined by a ring - Adds a querier and client component on the index gateway to filter chunk refs - Adds the gRPC protobuf definitions for commication between index gateways and bloom gateways - Adds a store component used on the bloom gateways to query binary bloom files ``` Querier Query Frontend \| \| ................................... service boundary \| \| +----+------+ \| indexgateway.Gateway \| bloomgateway.BloomQuerier \| bloomgateway.GatewayClient \| logproto.BloomGatewayClient \| ................................... service boundary \| bloomgateway.Gateway \| bloomshipper.Store \| bloomshipper.Shipper \| bloomshipper.BloomFileClient \| ObjectClient \| ................................... service boundary \| object storage not part of this PR ``` This PR still contains a lot of TODOs and possibilities for optimisations, which will be addressed in subsequent pull requests.
