Dylan Guedes 5d8c48bd10 Loki: Implement stream sharding (#6952) ... * introduce 'StreamSharder' interface to decouple sharding from managing shards * make the streamsharder take a whole stream instead of just and ID * Implement stream sharding usage. * move streamShard to distributor * Implement the stream sharder and shard iter (#6941) * Modify sharding to not duplicate all entries for all shards (#6942) * Modify sharding to not duplicate all entries for all shards. * Rename ShardIter and get rid of NextShardId method. * Get rid of ShardIter and ShardStats. * Implement a StreamSharder mock and use it in tests. * Rewrite stubbing and remove flags. * Add auto-splitting. * Only shard stream when approppriate. * Make sharding mode an enum. * Bench shardStream function. * Modify shard comparison to be <= 1. * Add a guard clause for when lowerbound>upperbound. * Apply suggestions from code review Avoid using `fmt.Sprintf`. Co-authored-by: Danny Kopping <danny.kopping@grafana.com> * Update pkg/distributor/distributor.go Rename metric name. Co-authored-by: Danny Kopping <danny.kopping@grafana.com> * Avoid double-negative by Danny's suggestion. * Move TODO to its right place. * Log scenario where upperbound < lowerbound. * Reuse compiled regex. * Add docstring explaining why we use max(shards*2, 2). * make sharder use a RWMutex * simplify sharding config * replace doc string * Revert "Add auto-splitting" for standalone PR. This reverts commit e3886a6210. * shard loop refactor * move shard creation into it's own function * fix after refactor * make config more explicit and document it * reduce allocations * review feedback Co-authored-by: Travis Patterson <travis.patterson@grafana.com> Co-authored-by: Danny Kopping <danny.kopping@grafana.com>		3 years ago
