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
