Description

Flushes all memtables from the node to SSTables on disk. DataStax Enterprise (DSE) stops listening for connections from the client and other nodes. You need to restart DSE after running nodetool drain. You typically use this command before upgrading a node to a new version of DSE. To simply flush memtables to disk, use nodetool flush.
