0 will not support query cache, and users upgrading will be encouraged to use either Server-side Query Rewrite or ProxySQL as a man-in-the-middle cache. With the current limitations noted, the query cache will continue to be supported for the life time of MySQL 5.
Throughout our benchmark, we’ve seen HBase consistently outperforming Cassandra on read-heavy workloads. HBase shines at workloads where scanning huge, two-dimensional tables is a requirement. This aligns well with the key use cases of HBase such as search engines, high-frequency transaction applications, log data analysis and messaging apps. Thus it’s more suitable for analytics data collection or sensor data collection when consistency over time is acceptable. On the other hand, Cassandra worked well on write-heavy workload trading off with consistency.
Wenisch at the University of Michigan, Ann Arbor. We considered what improvements we could make to query cache versus optimizations that we could make which provide improvements to all workloads. We concur with the research performed by Jiamin Huang, Barzan Mozafari, Grant Schoenebeck, Thomas F.

X fully; only accepts some ‘expected’ forms of responses. The rather heavy use of strstr(3) shows up top in profile, which might indicate a performance problem; i. , you would measure the ab performance rather than the server’s. It does not implement HTTP/1.
