MySQL V5.1 may find serious bugs or cause data loss

Sun released MySQL database software version 5.1 last week. Later, they said there were many bugs to fix, including new features. According to MySQL founder Michael Wideniu, the bug has been found to be very serious and may cause crash or even data loss. The bug of this version not only appears in the function, new features also have bugs.

It is reported that some bugs are related to the partition function. For example, it is difficult to restore the partition table after it crashes, and re-establishing the partition table will lead to data loss. Widenius stressed that, especially databases with multiple partitions are more likely to cause this problem. For this version, we recommend that you perform a test before deciding whether to deploy the database.
