Krati: A Persistent High-Performance Data Store

Krati is a simple persistent data store with very low latency and high throughput. It is designed for easy integration with read-write-intensive applications with little effort in tuning configuration, performance and JVM garbage collection.

Sounds a bit like Bitcask. Anyone can point out at least on the major differences?

From the project page:

  • supports varying-length data array
  • supports key-value data store access
  • performs append-only writes in batches
  • has write-ahead redo logs and periodic checkpointing
  • has automatic data compaction (i.e. garbage collection)
  • is memory-resident (or OS page cache resident) yet persistent
  • allows single-writer and multiple readers
