ConcourseDB

Key Features

* ACID Transactions - Concourse supports cross-record transactions that are fully ACID compliant: all operations succeed or fail together; writes are visible to all readers only after being successfully committed; serializable isolation is used to prevent dirty reads, non-repeatable reads and phantom reads; and committed transactions are immediately stored to disk so they persist in the event of power loss, crash or error * Version Control - Concourse automatically and efficiently tracks revisions to your data. * Automatic Indexing - Concourse automatically indexes everything in both logical and sorted order–using a buffered storage system to ensure that writes are fast–so you can quickly fetch and query any key at any time. * Simple Data Model - The Concourse data model is lightweight and flexible–it supports any kind of data at very large scales. * Scalability and Fault Tolerance - Concourse can be distributed across many different servers on commodity hardware to increase read and write throughput. * Graph Queries - The people, places and things in your data are all connected. So Concourse allows you to model those relationships with enforced referential integrity and also provides a built-in interface to perform analytical graph queries.
