Christian Haudum	78342c030a	chore(engine): Correctly propagate search direction to data object scan (#18112) ... The sort order of the physical plan was only used in the SortMerge node, but not on the DataObjScan. Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	1 year ago
Karsten Jeschkies	c2573fea5a	refactor(stringlabels): Support stringlabels in util, engine and logql. (#17998) ... This is a next step of support Prometheus `stringlabels` implementation in Loki. It adds support in the `util`, `engine` and `logql` packages. The tests should compile with build tag `stringlabels`.	1 year ago

Robert Fratto	a237444f0d	refactor(dataobj): invert dependency between dataobj and sections (#17762) ... Originally, the dataobj package was a higher-level API around sections. This design caused it to become a bottleneck: * Implementing any new public behaviour for a section required bubbling it up to the dataobj API for it to be exposed, making it tedious to add new sections or update existing ones. * The `dataobj.Builder` pattern was focused on constructing dataobjs for storing log data, which will cause friction as we build objects around other use cases. This PR builds on top of the foundation laid out by #17704 and #17708, fully inverting the dependency between dataobj and sections: * The `dataobj` package has no knowledge of what sections exist, and can now be used for writing and reading generic sections. Section packages now create higher-level APIs around the abstractions provided by `dataobj`. * Section packages are now public, and callers interact directly with these packages for writing and reading section-specific data. * All logic for a section (encoding, decoding, buffering, reading) is now fully self-contained inside the section package. Previously, the implementation of each section was spread across three packages (`pkg/dataobj/internal/encoding`, `pkg/dataobj/internal/sections/SECTION`, `pkg/dataobj`). * Cutting a section is now a decision made by the caller rather than the section implementation. Previously, the logs section builder would create multiple sections. For the most part, this change is a no-op, with two exceptions: 1. Section cutting is now performed by the caller; however, this shouldn't result in any issues. 2. Removing the high-level `dataobj.Stream` and `dataobj.Record` types will temporarily reduce the allocation gains from #16988. I will address this after this PR is merged.	1 year ago

Christian Haudum	1629181f9c	chore(engine): Unify name and type of builtin columns (#17608) ... Names and types used when creating and collecting records need to match. * `Entry.Line` maps to `builtin.message` of type `arrow.BinaryTypes.String` * `Entry.Timestamp` maps to `builin.timestamp` of type `arrow.FixedWidthTypes.Timestamp_ns` Signed-off-by: Christian Haudum <christian.haudum@gmail.com>	1 year ago
Christian Haudum	23c4f8d89a	chore(engine): Fix regression introduced with merging PR #17456 (#17578) ... `types.ColumnTypeMetadataKey` was renamed to `types.MetadataKeyColumnType` in https://github.com/grafana/loki/pull/17456 However, https://github.com/grafana/loki/pull/17568 was merged before that, which still used the old name.
