SQL Relay is a persistent database connection pooling, proxying, and load balancing system. It supports many database systems and programming languages. There are drop-in replacement libraries for MySQL and PostgreSQL, command line clients, a GUI configuration tool, and extensive documentation. The APIs support advanced database operations such as binding variables, multi-row fetches, client-side result set caching, suspended transactions, query routing, and query filtering. It can be used for speeding up database-driven Web-based applications, accessing databases from unsupported platforms, migrating between databases, distributing access to replicated databases, and throttling database access.
Release Notes: Support for a multi-threaded listener has been added. Major improvements have been made to the PHP PDO driver. Detection of various things in the configure script has been improved, including TCL on multi-arch systems and 64-bit Sybase and DB2. Many obscure, but significant bugs have been fixed, as well.
Release Notes: Errors in the documentation and bugs related to building on SCO OSR 5.0.0 and some libc5 systems have been fixed. A bug that caused "make clean" to fail partway through has been fixed.
Release Notes: Support has been added for the SQLite Statement API. A PHP PDO Driver has been added. The PHP Pear DB and Zope APIs have been removed. The init scripts have been refactored and should work on any Unix-like system now. Support for Mulitarch systems has been added.
Release Notes: Lots of minor, under-the hood modifications were made to support the most recent release of Rudiments. The sqlrsh program now reports the correct version and also supports running multiple, semicolon-delimited queries from the command line. The sqlr-export program has an option to output CSV now. A 64-bit build option is now available for Windows.
Release Notes: Support was added for Oracle 12c and DB2 10.1/10.5. Database installation documentation was updated. A few community-contributed patches were applied. An obscure issue regarding date conversions with FreeTDS and MS SQL Server in locales where dates are formatted DD/MM/YYYY was addressed and documented.
