Dylan Guedes	f9f1eddfc5	Loki: Improve query timeouts behavior (#7230) ... **What this PR does / why we need it**: Improves the different query-related timeouts behavior by fixing a bug and having better defaults. The changes are: - Fix the timeout middleware by creating a new request that will use the new WithDeadline context - `engine:timeout` was being ignored. This PR improves such scenario by using **the query timeout as a fallback** instead of the default `5min` for all cases	3 years ago
Dylan Guedes	f6f49ec6bb	Return Querier/QueryTimeout YAML configuration. (#6972) ... What this PR does / why we need it: On PR #6835 I mistakenly removed the querier:query_timeout YAML configuration. This PR returns it and uses it if it is still configured while logging a warning message to alert users of the upcoming changes.	3 years ago
Dylan Guedes	15f8f42295	Adapt queryTimeout to be a per-tenant configuration (#6835) ... What this PR does / why we need it: * Add a new per-tenant query timeout * Adds new middleware to query calls. This new middleware will timeout requests based on the new per-tenant query timeout * Add span logs to query calls missing it * Deprecate `engine.timeout` configuration The motivation to change this configuration to be per-tenant instead of global is that it makes sense to alleviate the timeout for particular tenants or make it more strict for others. Especially useful for scenarios where the Loki client doesn't handle context cancellations correctly; in such scenarios, since Loki would still process expensive queries that were canceled, this allows one to have small timeouts for most tenants, which will help mitigate unnecessary work without having a timeout that is too short for important tenants.	3 years ago

Karsten Jeschkies	3d5a3936d1	Support limits in multi-tenant queries. (#5626) ... **What this PR does / why we need it**: This changes adds support for the the following limits in multi-tenant queries: - `MaxQuerySeries` - `QuerySplitDuration` - `MaxEntriesLimitPerQuery` - `MinShardingLookback` - `MaxQueryLength` - `MaxQueryParallelism` - `MaxQueriersPerUser` - `MaxCacheFreshness` It always uses the more restricted limit. That means the smallest `MaxQuerySeries` but biggest `QuerySplitDuration`. The split duration is special. Zero means disabled. Also, the global default resolver is the multi tenant resolver when multi-tenant queries are enabled. This will result HTTP 400 errors in case the user sends multiple tenants to endpoints that do not support it. **Which issue(s) this PR fixes**: **Special notes for your reviewer**: **Checklist** - [ ] Documentation added - [x] Tests updated - [x] Add an entry in the `CHANGELOG.md` about the changes.
