> -----------------------------------------------------------------
>
> Key: IGNITE-18882
> URL: https://issues.apache.org/jira/browse/IGNITE-18882
> Project: Ignite
> Issue Type: Bug
> Reporter: Semyon Danilov
> Assignee: Semyon Danilov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-beta2
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> This test in AbstractMvPartitionStorageGcTest should pass
> {code:java}
> void testTombstoneFirst() {
> addAndCommit(null);
> addAndCommit(TABLE_ROW);
> addAndCommit(TABLE_ROW2);
> BinaryRowAndRowId row = pollForVacuum(HybridTimestamp.MAX_VALUE);
> assertRowMatches(row.binaryRow(), TABLE_ROW);
> }
> {code}
> At this moment, storages will store the tombstone if it is the first committed value which disrupts the GC flow.
> addWrite with null argument as a first version of row is valid, for example:
> {code:sql}
> CREATE TABLE test (
> id INT
> );
> BEGIN;
> INSERT INTO test VALUES(1);
> DELETE from test where id = 1;
> COMMIT;
> {code}
> is ok, but tombstone should not be stored (so the operation should be no-op)
