-------------------------------
Summary: Lazy execution of queries might produce wrong results
Key: FLINK-14293
URL: https://issues.apache.org/jira/browse/FLINK-14293
Project: Flink
Issue Type: Bug
Components: Table SQL / Planner
Reporter: Jark Wu
We introduced lazy execution of queries in FLINK-13088. But maybe we should
revisit it because if we have a sequence of statements like this:
{code:java}
tEnv.sqlUpdate("CREATE TABLE test (...) with (path = '/tmp1')");
tEnv.sqlUpdate("INSERT INTO test SELECT ...");
tEnv.sqlUpdate("DROP TABLE test");
tEnv.sqlUpdate("CREATE TABLE test (...) with (path = '/tmp2')");
tEnv.execute();
{code}
If we execute the create statements eagerly and the queries lazily we will end
up with wrong results.
