Project Description

OrientDB is a NoSQL DBMS which can store 150,000 documents per second on common hardware. Even with a document-based database, the relationships are managed as in graph databases, with direct connections among records. You can traverse entire or parts of trees and graphs of records in a few milliseconds. It supports schema-less, schema-full, and schema-mixed modes, has a strong security profiling system based on users and roles, and supports SQL between the query languages. Thanks to the SQL layer, it's straightforward to use for people skilled in the relational world.

0.9.11 (beta)

A new SQL layer was added on top of OrientDB. SQL Select, Insert, Update, and Delete were implemented. Now it's easy to use OrientDB from SQL backgrounders and importing a DBMS via SQL statements.

0.9.10 (beta)

Operator traverse now accepts optional parameters to limit the depth of recursivity: traverse(minDeep, maxDeep). any() and all() placeholders can accept a chain of such field operators. A database located in the $ORIENT_HOME/databases directory is automatically loaded and configured. Memory databases can be used and shared on any Orient Server instances.

0.9.9 (beta)

The SQL query engine was refactored to support external custom operators. POJO to ODocument conversion and performance was improved. New operators were added in test: any(), all(), and traverse(). The demo database was migrated from petshop to demo with a Twitter-like app called "Whiz", specially useful to test traversal of graphs. Constraints were implemented on date (min/max). A bug on circular references problem was fixed. The lazy-loaded list of pojo from ODocument is converted only upon request.

0.9.8 (beta)

This is the first real distributed Key/Value server with automatic partitioning of entries in the cluster nodes. Entries reside on multiple nodes. When a node crashes, the backup nodes rebalances the cluster entries.

0.9.6 (beta)

The Orient release was split in two: the database and the key/value server. Starting from now, the key/value server is distributed separately.
