Christian Haudum	cdf084fdae	perf(blooms): Remove compression of `.tar` archived bloom blocks (#14159) ... Decompression is a CPU intensive task, especially un-gzipping. The gain of compressing a tar archive of storage optimized binary blocks is neglectable (question: is it?). In this example, the block of ~170MiB is ~3.3MiB bigger when not compressed, which is a ratio of ~2% ```bash $ ls -las 2bc017f79711e12a-2bffc5dcc0e8e964_1726004114913-1726106283939-bc42f529.tar 177048 -rw-rw-r-- 1 christian christian 181293056 Sep 18 13:49 2bc017f79711e12a-2bffc5dcc0e8e964_1726004114913-1726106283939-bc42f529.tar $ ls -las 2bc017f79711e12a-2bffc5dcc0e8e964_1726004114913-1726106283939-bc42f529.tar.gz 173732 -rw-rw-r-- 1 christian christian 177897689 Sep 18 13:49 2bc017f79711e12a-2bffc5dcc0e8e964_1726004114913-1726106283939-bc42f529.tar.gz $ qalc '(181293056 - 177897689) / 1024/ 1024' ((181293056 − 177897689) / 1024) / 1024 ≈ 3.238074303 $ qalc '181293056 / 177897689' 181293056 / 177897689 ≈ 1.019086066 ``` After some consideration, we decided to store the encoding of the bloom block in the `BlockRef`. This means, that the changes in this PR do not break compatibility with existing blocks compressed with gzip, although new blocks will not be compressed any more. However, the PR adds support for different compression algorithms, such as gzip, snappy, lz4, flate, and zstd. Compression is not configurable yet. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	8 months ago
Paul Rogers	fc90a63636	feat: implement IsRetryableErr for S3ObjectClient (#14174) ... **What this PR does / why we need it**: Adds support for `IsRetryableErr`in the `S3ObjectClient`, similar to what is found in the `GCSObjectClient`	8 months ago

Christian Haudum	963779064b	chore: Move compression utilities into separate package (#14167) ... Compression tooling has been part of the `chunkenc` (chunk encoding) package in the past for legacy reasons. Since more components use this now, it's easier to keep it in a separate package. This also eliminates the confusion around "encoding", since this has been incorrectly used synonymously with "compression" in the past. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com> Co-authored-by: Robert Fratto <robertfratto@gmail.com>	8 months ago

Christian Haudum	6e36041c08	chore(blooms): Remove excessive logging in fused querier (#14152) ... The FusedQuerier emits a large amount of log lines at level WARN if a bloom is empty. Since the introduction of structured metadata blooms, this happens every time a series does not have structured metadata in any of its entries. In the future, an optimisation could be to not write blooms for series at all, if they contain no data. Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	9 months ago

Christian Haudum	e64124ec1a	chore(blooms): Expose series/stream metadata when iterating over blooms (#14097) ... The bloom block format stores metadata from indexing in the index part of the block (series file), which contains information, such as the fields (metadata names) that have been indexed in the bloom filter. This will be needed in the read path (bloom gateway) later on, to check whether a provided label name from the label filter expression was actually indexed or not. In this PR, the newly available metadata is used by the bloom inspect tool (located in ./tools/bloom/inspect/) to list the fields along the series, as well as the individual pages of the series that contain the actual scalable bloom filters. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	9 months ago

Christian Haudum	a2fbaa8e09	feat(blooms)!: Index structured metadata into blooms (#14061) ... Instead of indexing n-grams of the log line content, we index the plain values of the structured metadata keys and values. Resulting tokens are: * `name` * `chunkPrefix + name` * `value` * `chunkPrefix + value` * `name + '=' value` * `chunkPrefix + name + '=' + value` Indexed fields (metadata name) are also extracted into the series metadata. Indexed metadata values cannot be queried with the bloom gateways yet. This PR does not cleanup unused code used for ngram-tokenization, it is scope for a follow up. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	9 months ago

Paul Rogers	73cbbb0f22	feat: add retries for s3 ObjectExists calls (#14062) ... **What this PR does / why we need it**: It was determined via careful examination that Loki would issue retries for S3 `GetObject` calls, but would not retry calls to `ObjectExists`. For transient issues (e.g. rate-limiting), it makes sense to retry the command to see if an object does exist. If the object is not found (meaning, a 404 return code, and a successful query of the S3 storage to show the object does not exist), the retries are not leveraged, as it is not needed.	9 months ago
Christian Haudum	5395daf898	chore(blooms)!: Introduce a new block schema (V3) (#14038) ... A new schema version V3 for bloom blocks that is incompatible with old schemas. It simplifies some parts of the code and makes the schema more extensible, laying the groundwork for indexing structured metadata fields into bloom filters. ⚠️ This PR breaks the bloom filter functionality! Until the read path is implemented, bloom blocks created with the new schema cannot be queries in the bloom gateways. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	9 months ago

Christian Haudum	b75eacc288	chore(blooms)!: Remove bloom compactor component (#13969) ... **What this PR does / why we need it**: This commit removes the code related to the bloom compactor which is superseded by the bloom planner and builders. A handful of CLI arguments of per-tenant settings changed their prefix from `-bloom-compactor.*` to `-bloom-build.*`. Other settings for the compactor component itself, also prefixed with `-bloom-compactor.*` were removed. See upgrade docs for further information. **Special notes for your reviewer**: ✔️ Part of https://github.com/grafana/loki/issues/13957 📔 Documentation update https://github.com/grafana/loki/pull/13965 ⚠️ Integrating the bloom planner and builder into the `backend` target is done in a follow-up PR. --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	9 months ago

The root cause of this issue is that the error returned by `fmt.Errorf()` in `BloomClient` loses the underlying cause. As a result, `S3ObjectClient.IsObjectNotFoundErr()` fails to determine if the underlying cause of the returned error is of type `awserr.Error`.	10 months ago

Christian Haudum	2624a4bdd4	fix(blooms): Use correct key to populate blockscache at startup (#13624) ... The cache key for block directories in the blocks cache are the block's address without the directory prefix. This is how the directory is put to the LRU cache after downloading and extracting the block tarball. This PR fixes the incorrect cache key used to populate the cache from disk on startup, which contained the file system directory prefix. Since the cached item from startup is never used, it gets evicted first in case of a full cache, or due to its TTL. This causes also the underlying directory on disk to be deleted, which can however still be referenced from the correct cache key for that directory from a later download. That caused the error `getting index reader: opening series file: open /path/to/block/series: no such file or directory` when trying to query the block, because the correct cache key was still present.
