COMPRESSION IN CASSANDRA

COMPRESSION IN CASSANDRA Operators can set up compression on a per-table basis with Cassandra. By compressing the SSTable in user-configurable compression chunk_length_in_kb, compression minimizes the amount of data on disk. The CPU cost of compressing data is only required when the SSTable is written since… Read More
