nickva commented on issue #539: Close idle dbs URL: https://github.com/apache/couchdb/pull/539#issuecomment-304039061 This is a test restarting a 3 node cluster with 130k databases (100k regular and 30k "_replicator" dbs).  On the left is master and on the right is this PR. There were no requests issued to the cluster during this time. All activity is due to internal replication and replicator. Left side crashed and restarted after some point, probably due to high memory usage. Notice memory consumption and process count continue to rise after internal sync is finished due to the replicator having to launch change feeds and checkpoint 30k * 8 = 240k shards. Closing idle shards in this case has helped free enough memory to let replicator finish checkpointing all the shards. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
