Hi all, I have a keyspace with almost 900 tables.
Lately I started receiving lots of w/r timeouts (eg com.datastax.driver.core.exceptions.Read/WriteTimeoutException: Cassandra timeout during write query at consistency LOCAL_ONE (1 replica were required but only 0 acknowledged the write). *I'm even experiencing nodes crashing.* In the logs I get many warnings like: WARN [Service Thread]....GCInspector.java:282 - ConcurrentMarkSweep GC in 4025ms. CMS Old Ge n: 2141569800 -> 2116170568; Par Eden Space: 167772160 -> 0; Par Survivor Space: 20971520 -> 0 WARN [GossipTasks:1].....FailureDetector.java:288 - Not marking nodes down due to local pause of 5038005208 > 5000000000 I know 900 tables is a design error for C* but before a super painful refactoring I'd like to rule out any configuration problem. Any suggestion? Thanks a lot, Luca
