What it covers

Data storage systems and processes are provided including processes for handling write and read requests to a storage system. A storage system can include data stores, such as a log store, a hash store and a journal store. Data can be written to a log store, a log store can be converted to a hash store, and hash stores can be merged into a journal store. A storage system can use optimizations in writing and storing data, to provide lower latency, lower levels of write amplification and higher throughput.
