Universal Storage

Universal storage allows you to support large-scale Online Transaction Processing (OLTP) and Hybrid Transactional and Analytical Processing (HTAP) at a lower total cost of ownership (TCO). Universal storage is a continuing evolution of the columnstore, supporting transactional workloads that would have traditionally used the rowstore.

Although rowstores are well-suited for transaction processing, it can be costly to store large datasets in rowstores, as they store all data in RAM. Because columnstores are disk-based, it is more economical to store data in columnstores as opposed to rowstores.

Current Features in Universal Storage

Currently, universal storage has five features that allow columnstores to process transactional workloads more efficiently:

Additionally, sparse compression for rowstores enables wide tables with a large percentage of NULL values to be stored in as little as half of the RAM.

See SingleStore's Patented Universal Storage - Part 4 for a general discussion of all the capabilities of Universal Storage.
