+The IntelliJ Platform provides a simple API for accessing data under read or write locks in the form of read and write actions.
 
 Read and write actions allow executing a piece of code under a lock, automatically acquiring it before an action starts, and releasing it after the action is finished.

-> If the read operation itself is long, consider using one of [read action cancellability techniques](#read-action-cancellability) to avoid blocking the write lock and EDT.
