Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Shared base for the per-partition stores keyed by (view_name, partition_key): PartitionState (the cold-view fresh set) and SourceWatermark (the CDC watermark). Centralizes the primitives they must share — most importantly #serialize, which has to be identical across every store, or a mark and a watermark would key the same partition differently and lookups would silently miss.

A subclass supplies the three things that differ — its #record_class, #table_name, and the table-specific columns via #define_columns — and may override #ensure_columns! to lazily add a column introduced after the table was first provisioned.
