Sandeep Sukhani	e9c93cd0f5	consider range and offset in queries while looking for schema config for query sharding (#7880) ... **What this PR does / why we need it**: We disable query sharding when a query touches multiple schema configs since they might have different sharding factors and might handle sharding differently. This check was done purely on the start and end time of the query without considering `range` and `offset`, which would change the length of the actual data being queried. Besides being incorrect, it also causes us to fail queries when migrating between tsdb and non-tsdb stores since both handle query sharding differently. For e.g., if the prev schema is `boltdb-shipper` and starting today, `tsdb` index is being used, so if we do a query `sum(rate({foo="bar"}[24h])` even with start and end within `tsdb` range, we will fail the query with error `incompatible index shard` if dynamic sharding goes with shard factor other than `32`(default shard factor in ingester for inverted index). The reason being the `range` here is `24h` which causes us to process data from previous schema as well. This PR takes care of the issue by factoring in `range` and `offset` in the queries while looking for schema config for query sharding. **Checklist** - [x] `CHANGELOG.md` updated	3 years ago
Owen Diehl	22089415e8	Split parallelism across Period Configs (#7769) ... One of things we watch while updating non-TSDB period configs to TSDB period configs is the difference in query parallelism. TSDB dynamically shards queries into (potentially) much smaller units of work compared to the static shard factors uses prior. To account for this, we use much higher query parallelism configurations with TSDB period configs. This creates a potential problem when querying across `non-tsdb, tsdb` period boundaries: we may want a query parallelism of 512 for the tsdb portion but only 64 for the non-tsdb portion! However, we only had one limit to specify this per tenant, meaning this would be too high when querying non-tsdb periods or too low when querying tsdb ones. This PR * Introduces `tsdb_max_query_parallelism` (default `512`) to `limits_config` * Uses `tsdb_max_query_parallelism` and `max_query_parallelism` limits to find a better parallelism _per query_ by weighting the two respective configs by the proportion of each query spent on TSDB or non-TSDB period configurations.

Travis Patterson	f2297d3d2a	Fix result cache misses on sharded queries (#7429) ... Headers weren't being propagated from query responses on sharded queries causing result cache misses. This PR: - Adds headers to `logproto.Result` so we can save response headers as they come back from queries - Metric-query results are turned into numbers well away from where responses are sent to the frontend: save all headers in the context so they can be pulled out when the final result is calculated - Propagate headers in the final responses	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
