benclive	2ce207fbdb	chore: Use shared zstd encoders during dataobj build (#20044)	1 month ago
Christian Haudum	73bc30d9a8	perf(engine): Improve regexp expression evaluation (#19644) ... This PR changes the evaluation of regex-match binary expression evaluations so that the regexp on right hand side of the expression is only compiled once for each batch evaluation, rather than for each row. This saves a ton of allocations and improves general performance of queries with a regexp line or label filter.	2 months ago

Christian Haudum	4c81ebc7c3	chore(dataobj): Add option to set target row limit for pages (#19128) ... This PR introduces an option for the column builder to limit the number of rows in a page. It can be set for logs object and index objects separately using `-dataobj-consumer.max-page-rows` and `-dataobj-index-builder.max-page-rows` respectively.

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.	8 months ago
