Change Log

Bugfixes

1. Fix the bug that, in previous versions, one auto-increment duplicate error could trigger other threads to have duplicate errors at high concurrency.
2. Fix a bug of the wrong result of affected rows in executing UPDATE JOIN.
3. Solved the problem of empty data/excess data/no matching rows when TSpider needs to replace a new shard under UPDATE / UPDATE JOIN. The cause of the error is related to the FLOAT column and the execution plan.
4. Avoid the empty query Bug when TSpider executes SQLs under specific scenarios.
