Expand description
Multi-version storage backend for OLTP traffic, tiered as in-memory commit buffer over a pluggable
persistent tier. Invariant: a row at version V is what a reader whose snapshot is >= V sees when no
later version exists at V' <= snapshot, and a commit must publish all its deltas atomically to readers.
Modules§
- config
- flush
- Background flusher that migrates writes from the buffer tier to the persistent tier. Flush is the watermark-coupled eviction sweep: on each tick (or explicit request) it persists the latest-<=W value per key of every persistent object, then drops all <=W versions from the commit tier, bounding the commit tier’s RAM.
