Using Thread Safety in Cache Management

Using Thread Safety in Cache Management

When you perform structural changes on your cache, such as creating or closing a Cache, Pool, or Region, synchronize your operations or do them in a single thread.

Other non-structural operations, like region gets, puts, and queries, are thread safe, and you can perform them in a multithreaded way. There are caveats to this, for example, when two threads update the same key simultaneously, there is no way to determine which thread's operation will prevail.

You may need to protect cached objects from concurrent usage and modification. The native client does not guard cached objects themselves from concurrent access.

Always catch and handle exceptions that may be thrown, for problems like trying to create a Pool with the same name more than once.
