Reducing Locking Issues

  • Chapter
  • First Online:
MySQL Concurrency

Abstract

Remember that the locking in MySQL and InnoDB is a means to provide concurrent access, and in general the fine-grained locking of InnoDB allows for a highly concurrent workload. Yet, if you have excessive locking, it will cause reduced concurrency and query pileups, and in the worst case, it can cause an application to come to a grinding halt and cause a poor user experience.
