The Cassandra Memory Layer

Using the tests mapped to this layer, administrators can proactively detect:

  • irregularities in the sizing of the buffer pool
  • Poor responsiveness of the cache
  • Poor cache usage
  • Delays in flushing writes to disk due to over growth of the commit logs
  • Potential disk space crunch due to irregularities in the compaction process
