Swoole provides 6 different memory operation APIs: Lock, Buffer, Table, Atomic, MMap, Channel which can be used when developing multiple process programs.
All these API are async and non-blocking, multiple-process safe. Don't have to warry about the data sync issues.
Swoole Lock {#entry_h2_1}
Swoole locks enable PHP developers use locks for data synchronization between multiple theads or processes.
