Is it related to https://issues.apache.org/jira/browse/CASSANDRA-4973? And https://issues.apache.org/jira/browse/CASSANDRA-4785?

You experience is not uncommon. There was a recent thread on this with a variety of details on when to use row caching:

tl;dr - it depends completely on use case. Small static rows work best.

I'm running the Cassandra 1.2.4 and when I enable the row_cache, the system throws TImeoutExcpetion and Garbage Collection don't stop.

When I disable the query returns in 700ms.

Configuration:

  • row_cache_size_in_mb: 256
  • row_cache_save_period: 0
  • # row_cache_keys_to_save: 100
  • row_cache_provider: SerializingCacheProvider

Why is this happening?


Thanks in advance!!
