Description
Certain Redis commands (specifically, SETEX, but there are others) have been marked as deprecated since Redis v2, and are slated for future removal. Audit the code base and replace deprecated commands with modern syntax.
Deprecated Redis commands can be discovered by running any Redis instance and executing the command COMMAND DOCS [command-name] [command-name] ... and grepping for deprecated_since
(Interestingly, SETEX doesn't show up as officially deprecated, but the Redis docs web page list it as such)
