Sun warns of bugs as it releases MySQL 5.1
Summary
Topics
Michael 'Monty' Widenius, the founder of MySQL, stated in a blog post on Saturday that most of the issues identified were serious or crashing bugs. Not all problems are related to the new features; there are a number of older, known bugs that are still present in this release.
The new features introduced have been ranked as 'beta' quality. There are a number of issues associated with the partitioning feature, such as the difficulty to restore a partitioned table if it crashes, and the chance of losing all data in the event of a server crashing during the rename table feature of a partitioned table. Widenius highlighted that the feature was inefficient, particularly if there were many partitions in a database.
Row-based replication has not been enabled by default, because of a number of problems. Users are advised to test the latest MySQL version before deploying it to production systems.
Just In
As far as the warning to test before deployment goes... I've seen PLENTY of ID-10-Ts out there deploy "BETA" quality software anyway, without a backup, without any sort of easy recourse should the manure hit the fan, on their production systems and get bit hard on their backsides.
instead of adding features. I secondly question the purpose
of including features that are of beta quality - if they need
'real world testing' then they should have included one which
is 'hard as rocks stable' and one which compiles in the
bleeding edge features for those who like to live on the edge.
Then again, this is Sun - so this kind of stupidity really
doesn't surprise me.
