What benefits do I get by running in-memory in DataStax Enterprise?
DSE In-Memory allows users to create memory-only database objects with faster performance over objects that are standard disk or SSD-based. Typical scenarios that benefit from DSE’s in-memory option include those with primarily read-only workloads with slow changing data and/or semi-static datasets.
Data protection and durability ensure that no data is lost due to power failure or other problems. From a developer perspective, there is no difference in working with an in-memory database object versus a traditional disk-based table.
