The Apache Derby project is pleased to announce feature release 10.10.1.1.
Apache Derby is a subproject of the Apache DB project. Derby is a pure
Java relational database engine which conforms to the ISO/ANSI SQL and
JDBC standards. Derby aims to be easy for developers and end-users to
work with.
Derby 10.10.1.1 can be obtained from the Derby download site:
http://db.apache.org/derby/derby_downloads.html.
Derby 10.10.1.1 contains the following new features:
* JDBC 4.2 - Derby supports the Java 8 enhancements to JDBC.
* Small device profile - Derby runs on the small CP2 profile of
Java 8. See the corresponding JEP at http://openjdk.java.net/jeps/161
* User-defined aggregates - Applications can create their own
aggregate operators. See the "CREATE DERBY AGGREGATE" section in the
Derby Reference Manual.
* Varargs routines - SQL routines can be bound to user-written Java
methods which have variable length argument lists.
* Optional tools - Derby has new, optional tools to support data
migration and metadata queries. See the "Optional tools" section in the
Derby Tools and Utilities Guide.
* SYSCS_UTIL.SYSCS_INVALIDATE_STORED_STATEMENTS - Derby has a new
system procedure for invalidating stored prepared statements when you
think that your metadata queries or triggers are misbehaving--for
example if they throw a NoSuchMethodError on execution. See the section
on this new system procedure in the Derby Reference Manual.
* Faster query compilation - A number of changes have made SQL
compilation faster.
* Unencrypting databases - Encryption can be turned off on existing
databases. See the section on the decryptDatabase attribute in the Derby
Reference Manual.
In addition, Derby 10.10.1.1 contains many bug, security, and
documentation fixes.
