class InMemoryLogReplay extends LogReplay

Replays a history of actions, resolving them to produce the current state of the table. The protocol for resolution is as follows:

  • The most recent AddFile and accompanying metadata for any (path, dv id) tuple wins.
  • RemoveFile deletes a corresponding AddFile and is retained as a tombstone until minFileRetentionTimestamp has passed. A RemoveFile "corresponds" to the AddFile that matches both the parquet file URI *and* the deletion vector's URI (if any).
  • The most recent version for any appId in a SetTransaction wins.
  • The most recent Metadata wins.
  • The most recent Protocol version wins.
  • For each (path, dv id) tuple, this class should always output only one FileAction (either AddFile or RemoveFile)

This class is not thread safe.
