Can I reuse the execution context while using a lambda function - AWS

Question

Can I reuse the execution context while using a lambda function in AWS?

Answer 1

Yes, of course, you can! Using it, in fact, increases the performance of your function. Make sure any externalized configuration or dependencies that your code retrieves are stored and referenced locally after initial execution. Limit the re-initialization of variables/objects on every invocation. Instead use static initialization/constructor, global/static variables and singletons. Keep alive and reuse connections (HTTP, database, etc.) that were established during a previous invocation.
