Christian Haudum	a0f358fcc8	fix(blooms): Fully deduplicate chunks from FilterChunkRef responses (#12807) ... This PR aims for full de-duplication of chunks and series from filter requests from the index gateway to the bloom gateway. Whenever we merge/de-duplicate slices, the inputs need to be sorted. It appears that the Removals (chunks) from the v1.Output are not guaranteed to be sorted. When comparing ShortRefs, both From, Through, and Checksum need to be used.

Christian Haudum	5540c92d50	perf(blooms): Resolve bloom blocks on index gateway and shard by block address (#12720) ... This pull request changes how data is sharded across bloom gateways. Currently, chunks are grouped by series and shared by the fingerprint of the series across the available bloom gateways using jumphash algorithm. This however, leads to over-querying bloom blocks, because bloom blocks have consecutive fingerprint ranges, whereas sharding keys are evenly distributed across keyspace. This PR changes the sharding in the way that bloom blocks for series are already resolved on the index gateways and that their address is used for sharding data. This has the advantage that the grouped series can be mapped to the correct bloom blocks on the client side. Sending the block ref along with the grouped series to the bloom gateway allows for efficient querying of the data because each bloom gateway therefore owns exactly 1/nth of the blocks. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	1 year ago

Christian Haudum	62176339c4	Bloom querying: Propagate line filters from querier to bloom filter (#11492) ... In order to query the bloom filters with the search strings from the user query, we need to propagate the line filters through the different implementations of the store, namely through the GetChunks function. In order to avoid converting data structures, the line filter from the syntax tree is used as custom protobuf type, because it is passed from querier to index gateway and from index gateway to bloom gateway. So far, the line filters request have not been tokenized to n-grams. This PR adds the ability to read the n-gram length from the block schema at query time and tokenizes the line filters from the input just ahead of searching the block.

Salva Corts	a0b462d366	Bloom-Gateway cache (#11380) ... **What this PR does / why we need it**: This PR adds caching to the bloom-gateway client. It uses the result cache from https://github.com/grafana/loki/pull/11343. Here's how we: - Merge responses: group all chunks by FP and remove duplicated chunk checksums. - Extract responses based on time span: For all chunks in each FP, add to the extracted response only the chunks that overlaps with the desired start and end time.	2 years ago
