Module compactor 

Structs

CompactionRegion

CompactionRegion represents a region that needs to be compacted. It’s the subset of MitoRegion.

CompactionVersion

Region version for compaction that does not hold memtables.

DefaultCompactor

DefaultCompactor is the default implementation of Compactor.

DefaultSstMerger

The production SstMerger that reads, merges, and writes SST files.

MergeOutput

[MergeOutput] represents the output of merging SST files.

OpenCompactionRegionRequest

OpenCompactionRegionRequest represents the request to open a compaction region.

Traits

Compactor

Compactor is the trait that defines the compaction logic.

SstMerger

Trait for merging a single compaction output into SST files.

Functions

known_max_input_sequence 🔒

Computes the maximum target-domain sequence bound of the output of merging inputs. Foreign files are described by their target-local barrier; local trusted files use their physical sequence bound. Unknown bounds never become trusted through a partial maximum.

open_compaction_region

Open a compaction region from a compaction request. It’s simple version of RegionOpener::open().

sst_info_from_file_meta 🔒

Builds an SstInfo for the remote-compaction path by copying the scalar fields that FileMeta also carries.
