Re: MySQL gets long semaphore locks on dict0dict.cc - but on DML operations

Is there any kind of transaction around the SELECT + DELETE? Otherwise, two threads might grab the same item? Please elaborate on things like the number of inserting threads, the number of worker threads, how long it takes to process one item, etc.
