--------------------------------------------
Summary: Full repair on a keyspace with a large amount of tables
causes OOM
Key: CASSANDRA-17787
URL: https://issues.apache.org/jira/browse/CASSANDRA-17787
Project: Cassandra
Issue Type: Bug
Reporter: Brandon Williams
Running a nodetool repair -pr --full on a keyspace with a few hundred tables
will cause a direct memory OOM, or lots of heap pressure with
use_offheap_merkle_trees: false. Adjusting repair_session_space_in_mb does not
seem to help. From an initial look at a heap dump, it appears to node is
holding many _remote_ trees in memory.
