Bitsy is a small, fast, embeddable, durable in-memory graph database that is compatible with Tinkerpop3.
It is based on these design principles: “No seek” (avoid disk seeks to maximize write throughput), “No socket” (embed within the application to reduce network/OS delays) and “No SQL” (leverage graph traversals for faster queries).
This is free and open source software.
Features include:
- Support for Apache Tinkerpop aka Tinkerpop3.
- ACID guarantees on transactions.
- Designed for multi-threaded OLTP applications.
- Implements optimistic concurrency control.
- Data stored in readable text files.
- Serialization using the Jackson JSON processor.
- Recovers cleanly from power failures and crashes provided the underlying file system supports metadata journaling, like NTFS, ext3, ext4, XFS and JFS (not FAT32 or ext2).
- High read and write throughputs in multi-threaded environments.
- Supports online backups through a JMX interface.
