> ASTSingleTableModel was created in CASSANDRA-20156 and is used to validate
> that C* returns the correct response. Last night a false positive was listed
> {code}
> 1: INSERT INTO ks1.tbl (pk0, ck0, s0, v0, v1, v2, v3) VALUES (false, false,
> 'S' + '#', 0x7b, '21:54:38.042512095', -1220695853 + 487670685,
> 00000000-0000-1a00-b300-000000000000) -- on node1
> 10: UPDATE ks1.tbl SET s0='\u001C{c|\u001Dz' + '\u0006rO\u0007``',
> v0=0xfffa8e324eb60d5510, v1='05:09:16.823129832', v2=519617565,
> v3=00000000-0000-1e00-b100-000000000000 WHERE pk0 = true AND ck0 = true -- on
> node1
> 27: DELETE FROM ks1.tbl WHERE pk0 = false AND ck0 = false -- on node1
> 69: DELETE s0 FROM ks1.tbl WHERE pk0 = false -- on node1
> 72: SELECT * FROM ks1.tbl WHERE token(pk0) = token(false) -- by token, on
> node1, fetch size 1
> Caused by: java.lang.AssertionError: Unexpected results for query: SELECT *
> FROM ks9.tbl WHERE token(pk0) = token(false) Caused by:
> java.lang.AssertionError: No rows returned Expected: pk0 | ck0 | s0 | v0 | v1
> | v2 | v3 false | null | null | null | null | null | null
> {code}
> The issue is the delete static column didn’t check if the partition is no
> longer referenced, so the read path included it as expected. The read path
> should have also filtered out this case as well
