Is DB thread-safe?

[hlms]

Hello team,

I'm passing a same DB object to multiple threads, and they all will invoke commit() methods. I hope DB object is thread-safe. Please correct me if that is NOT the case.

DB db = DBMaker.fileDB("file.db")
            .checksumHeaderBypass()
            .transactionEnable()
            .closeOnJvmShutdown()
            .make();
