Re: How to resolve "Lock wait timeout exceeded" issue reported by MySQL Cluster

Hi Mikael,

Thank you very much for your reply.

My team worked with MySQL InnoDB before this new project.

In current new project, we decide to use MySQL Cluster as our core database system.

So our team members know InnoDB well, but they are the freshman in MySQL Cluster.

When this issue happened in MySQL Cluster, they guess such issue maybe come from NDB Engine special technical characteristics .

I read MySQL Cluster document, there is no document mentioned about this issue.

So our team should not put Clues to solve on NDB Engine itself, right ?

It should be mistakes from our Java transaction logic.

Best Regards,
Hu Jingyu
