Thanks for your pull request. Instead of adding a new method with a different name, we should introduce overloads accepting keepTtl as boolean option. KEEPTTL can be combined with XX and NX but not PX/EX options.

Care to update your pull request?

@mp911de Hi~ Do you mean like this?
Boolean set(byte[] key, byte[] value, Expiration expiration, SetOption option, boolean keepttl);

[mp911de]

Yes, exactly.

@mp911de Got it. Thanks. That was updated.

Thank you @dengliming. We changed the original PR a bit and merged it to the main line.
To ensure existing behaviour is not broken or changed, please make sure to run all tests (with the -DrunLongTests=true flag) - thanks!
