Understanding the Top 5 Redis Performance Metrics

0 comments

Redis is an in-memory, persistent, key-value store that supports more than strings. MongoDB doesn't have in-memory and key-value attributes while Memcached doesn't have persistence or support for more than strings. Redis, by contrast, doesn't have support for larger-than-memory datasets and it's not multithreaded.

  2. Number of commands processed: total_commands_processed 
  3. Latency 
  4. Fragmentation Ratio 
  5. Evictions
