  • Very fast database engine
  • Open source
  • Written in Java
  • Supports standard SQL, JDBC API
  • Embedded and Server mode, Clustering support
  • Strong security features
  • The PostgreSQL ODBC driver can be used
  • Multi version concurrency
  • In-memory databases
  • Browser based Console application
  • Small footprint, around 1 MB jar file size.
  • Pure Java
  • Memory Mode
  • Encrypted Database
  • ODBC Driver
  • Fulltext Search
  • Additional Features:
  • Disk based or in-memory databases and tables, read-only database support, temporary tables
  • Transaction support (read committed and serializable transaction isolation), 2-phase-commit
  • Multiple connections, table level locking
  • Cost based optimizer, using a genetic algorithm for complex queries, zero-administration
  • Scrollable and updatable result set support, large result set, external result sorting, functions can return a result set
  • Encrypted database (AES or XTEA), SHA-256 password encryption, encryption functions, SSL
  • SQL Support:
  • Support for multiple schemas, information schema
  • Referential integrity / foreign key constraints with cascade, check constraints
  • Inner and outer joins, subqueries, read only views and inline views
  • Triggers and Java functions / stored procedures
  • Many built-in functions, including XML and lossless data compression
  • Wide range of data types including large objects (BLOB/CLOB) and arrays
  • Sequence and autoincrement columns, computed columns (can be used for function based indexes)
  • ORDER BY, GROUP BY, HAVING, UNION, LIMIT, TOP
  • Collation support, users, roles
  • Compatibility modes for IBM DB2, Apache Derby, HSQLDB, MS SQL Server, MySQL, Oracle, and PostgreSQL.
  • Security Features:
  • Includes a solution for the SQL injection problem
  • User password authentication uses SHA-256 and salt
  • For server mode connections, user passwords are never transmitted in plain text over the network (even when using insecure connections; this only applies to the TCP server and not to the H2 Console however; it also doesn't apply if you set the password in the database URL)
  • All database files (including script files that can be used to backup data) can be encrypted using AES-128 and XTEA encryption algorithms
  • The remote JDBC driver supports TCP/IP connections over SSL/TLS
  • The built-in web server supports connections over SSL/TLS
  • Passwords can be sent to the database using char arrays instead of Strings
  • Other Features and Tools:
  • Small footprint (smaller than 1 MB), low memory requirements
  • Multiple index types (b-tree, tree, hash)
  • Support for multi-dimensional indexes
  • CSV (comma separated values) file support
  • Support for linked tables, and a built-in virtual 'range' table
  • EXPLAIN PLAN support, sophisticated trace options
  • Database closing can be delayed or disabled to improve the performance
  • Web-based Console application (translated to many languages) with autocomplete
  • The database can generate SQL script files
  • Contains a recovery tool that can dump the contents of the database
  • Support for variables (for example to calculate running totals)
  • Automatic re-compilation of prepared statements
  • Uses a small number of database files
  • Uses a checksum for each record and log entry for data integrity
  • Well tested (high code coverage, randomized stress tests)

What's New in This Release:
  • MVStore: improved error messages and logging; improved behavior if there is an error when serializing objects.
  • OSGi: the MVStore packages are now exported.
  • With the MVStore option, when using multiple threads that concurrently create indexes or tables, it was relatively easy to get a lock timeout on the "SYS" table.
  • When using the multi-threaded option, the exception "Unexpected code path" could be thrown, specially if the option "analyze_auto" was set to a low value.
