Sophie Waldman	98b411a649	chore(linter): Fix issues flagged by updated golangci-lint version (#19206)	4 months ago
Karsten Jeschkies	8e37d5f817	chore: Remove unnecessary errors from splitter. (#16109) ... **What this PR does / why we need it**: Originally the splitter middleware had to parse the query and thus could return an error. However, parsing is done earlier now so no error is returned.	11 months ago

Danny Kopping	e7b782b186	Query-frontend: use the same query split interval for generated cache keys (#11679) ... **What this PR does / why we need it**: Follow up from #11535 (specifically from [this thread](https://github.com/grafana/loki/pull/11535#issuecomment-1887151515)), this PR modifies the results cache implementation to use the same interval for generating cache keys.	2 years ago
Danny Kopping	bcd03150c9	Query-frontend: customisable query splitting for queries overlapping `query_ingester_within` window (#11535) ... **What this PR does / why we need it**: The config option `query_ingesters_within` defines the window during which logs _could_ be present on ingesters, and as such queriers will send queries to ingesters instead. `split_queries_by_interval` is defined to split queries into subqueries for increased parallelism. Aggressive query splitting within the `query_ingesters_within` window can result in overloading ingesters with unnecessarily large numbers of subqueries, which perversely can impact writes. `query_ingesters_within` is set to 3h by default. In Grafana Cloud Logs we set `split_queries_by_interval` as low as 15m (defaults to 1h), which would result in result in 3*60/15=12 requests. Every querier queries every ingester during this window, so that's 12 requests _per ingester per query_ which has the `query_ingesters_within` window in its time range _(i.e. a query from now to now-7d would include the `query_ingesters_within` window as well, now-3h to now-7d would not)_. However, we _do_ want to split queries so an ingester won't have to handle a query for a full `query_ingesters_within` window - this could involve a large amount of data. To account for this, this PR introduces a new option `split_ingester_queries_by_interval` on the query-frontend; this setting is disabled by default. 	2 years ago
