There was a problem hiding this comment.
StaticTable also needs to override this and return NotSupported. Otherwise a read-only StaticTable inherits Table::NewMergeAppend(), creates a mutating snapshot update, and later hits the null catalog path during commit. The existing static-table test should cover this alongside NewFastAppend.

Let's rebase to resolve conflicts and perhaps address above findings. |
While adding merge append tests, it was discovered that FastAppend did not populate manifest count summary fields, thus add SnapshotUpdate::BuildManifestCountSummary and use it from FastAppend and MergingSnapshotUpdate, which is consistent with java implementation.
