---------------------------
Summary: SqlQueryBasedTransformer leaks temp views in continuous
mode
Key: HUDI-3670
URL: https://issues.apache.org/jira/browse/HUDI-3670
Project: Apache Hudi
Issue Type: Bug
Components: deltastreamer
Reporter: Ji Qi
In the Sql transformers, a new temp view with a random name is created for each
incoming batch, but the temp view is never dropped.
This causes a resource leak in Spark SessionState's Catalog. For long-running
deltastreamer jobs, the temp views created causes HiveSessionCatalog to take up
a lot of memory.
