Stephan Pirnbaum updated CALCITE-3869:
--------------------------------------
Attachment: stackoverflow.txt
> Stackoverflow with large OR statements
> --------------------------------------
>
> Key: CALCITE-3869
> URL: https://issues.apache.org/jira/browse/CALCITE-3869
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.22.0
> Reporter: Stephan Pirnbaum
> Priority: Major
> Attachments: stackoverflow.txt
>
>
> As described in CALCITE-2792 large OR clauses lead to a StackOverflowError.
> While the ticket was closed with the remark "Resolved in release 1.22.0", the
> issue originally stated was not (completely) resolved. To reproduce this, I
> implemented following simple test case:
> {code:java}
> @Test
> public void testLargeOr() {
> String orClause = IntStream.range(0, 1000).boxed()
> .map(i -> "e.\"empid\"=" + i)
> .collect(Collectors.joining(" OR "));
> final String sql = "SELECT * FROM \"hr\".\"emps\" e WHERE " + orClause;
> CalciteAssert.model(JdbcTest.HR_MODEL)
> .query(sql)
> .runs();
> }{code}
>
> The stackoverflow can be seen in the attached log.
> As also CALCITE-2696 and CALCITE-2630 are not fixed, this is a blocking issue
> in our current use case.
