changeset abstract method
Returns records in table in CrdtChangeset format.
When sinceHlc is non-null, only records modified after that HLC string
are returned; when untilHlc is non-null, only records at or before it.
Both bounds are parsed and compared as HLCs, never as raw strings. Pass
neither (the default) for the full table, including tombstones — required
for persistence and sync; the bounded form serves range reconciliation's
leaf fetches.
Implementation
Future<CrdtChangeset> changeset(
String table, {
String? sinceHlc,
String? untilHlc,
});
