As a non-relational database, HBase (Hadoop Data Base) is an open source data storage system based on column cluster and is applied wisely. The HBase will write the log file before the memory caches data, so the cache size and the writing speed of the log file have become two important factors affecting the system performance. Based on backup log, this paper proposes a persistence and availability scheme OLP (Other Log Process), which makes HBase can achieve better performance in different cache sizes. Experiments show that under the premise of ensuring the persistence and availability of data, OLP can obtain stable performance under different cache sizes, and obviously improve the time performance of write operation when the cache does not exceed the default settings.
