MySQL to Adopt Solid Storage Engine
hmart writes "As seen on ZDNet's Open Source Blog MySQL is taking another step to defend from Oracle's recent acquisitions of InnoBase and Sleepycat. From the article: 'MySQL responds by getting Solid Information Technology, a proprietary database vendor, to take its solidDB Storage Engine for MySQL open source, under the GPL, starting in June.'"
If there is a problem with mySql, one could always migrate to Postgresql. Postgresql is well known for its advanced features and its excellent ability to work with large-size dbs.
you could give postgresql a look-see. Might be your answer.
