Dylan Guedes	ea13730e63	feat: Snapshopt stream overrides values on each request (#16523) ... **What this PR does / why we need it**: Caches a snapshot of resolved policies and retention temporarily to guarantee consistent results on the same request. We evaluate retention and policies in a map when emitting some metrics so having policies or retention inconsistent along the chain for the same push request can cause us to miscalculate things or worse, interact with a nil map.	10 months ago

Dylan Guedes	3d6163abc7	fix: Fix blocked ingestion returned error when 260 (#16387) ... **What this PR does / why we need it**: Modify how we handle blocked ingestion errors: * If it is 200, don't expose any error * Otherwise, expose the error as the configured statusCode, but only if no other validation error occur. I'm calling this a secondTierErr Also modifying the enforced labels error message to log present labels.	11 months ago

Dylan Guedes	69089eff41	feat: Add support for blocking a policy to be ingested (#16203) ... **What this PR does / why we need it**: Add support for blocking a policy from being ingested. The policy is defined by stream mapping.	11 months ago

Dylan Guedes	5c8e832260	feat: Introduce policy stream mapping (#15982) ... **What this PR does / why we need it**: Introduces the idea of policies to Loki, which are recognizable based on the given stream selectors. This is an improved version of https://github.com/grafana/loki/pull/15561 and built on top of https://github.com/grafana/loki/pull/15875. A policy mapping can be configured the following way: ```yaml 12345: policy_stream_mapping: policy6: - selector: `{env="prod"}` priority: 2 - selector: `{env=~"prod|staging"}` priority: 1 - selector: `{team="finance"}` priority: 4 policy7: - selector: `{env=~"prod|dev"}` priority: 3 ``` With that configuration, pushes to tenant `12345` with the labels `{env="prod", team="finance"}` would be assigned to policy6 because the third mapping for policy6 matches these labels and has higher priority than any other matching.	11 months ago

Dylan Guedes	0bc23db95d	refactor: Add retention hours to `discarded` metrics (#15875) ... **What this PR does / why we need it**: We have no distinction between the type of data that gets discarded. On this PR I'm adding `retention_hours` to our discarded metrics so that we can better look at what data was discarded.	11 months ago

Christian Haudum	1a9f382e6f	chore: Remove experimental bloom settings that have never been used or are not used any more (#15787) ... Remove experimental results cache for bloom gateway client This feature never made it into production. Since it is only an experimental feature, it can be removed without prior deprecation. Remove unused `bloom_gateway_shard_size` runtime setting The setting was once used when bloom gateways still used a ring for sharding.

Dylan Guedes	a2c8ec7dc1	feat: Add a new `enforced_labels` limit (#15704) ... **What this PR does / why we need it**: Introduce the new experimental `enforced_labels` limit. By default it is empty but when configured, it configures Loki to only accept push requests which streams have all enforced labels.	12 months ago
Christian Haudum	7033091bc9	feat: Detect fields based on per-tenant configuration and put them into structured metadata at ingest time (#15188) ... This PR introduces a new feature that allows for extraction of "fields" into structured metadata at ingest time. Fields can either be regular labels, structured metadata keys, or keys from `logfmt` or `json` formatted log lines. The fields are defined in a per-tenant configuration as `map[string][]string`, where the key is the target key of the structured metadata, and the value is the list of source fields in given order and the order given above. Example configuration: ```yaml limits_config: discover_generic_fields: fields: trace_id: - "trace_id" - "TRACE_ID" - "traceID" - "TraceID" org_id: - "org_id" - "tenant_id" - "user_id" ``` While parsing of log lines comes with a certain penalty at ingest time (increased latency and CPU usage on distributors), the idea is to extract certain fields once to avoid parsing the log lines every single time at query time. This is mainly useful in combination with bloom filters. **JSONpath support** Should the value of the config map support jsonpath expression, such as ``` limits_config: discover_generic_fields: fields: ticket_id: - "message.ticket.id" ``` Where the log line looks like this: ```json {"timestamp": 1733128051000, "message": {"ticket": {"id": "2024-d95f87018cdb1f10"}}} ``` --- Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	1 year ago

Christian Haudum	f52f8ad540	chore: Clarify compression package (#14257) ... This PR renames "encoding" to "codec" in the compression package to remove the cognitive dissonance. It also removes the `Enc` prefix for codec identifiers, so that they adhere Go's best practice of naming conventions, e.g. `compression.EncGZIP` becomes `compression.GZIP` when used in a different package.

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>	1 year 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>	1 year ago
