Question 1

How do I use Delphi Redis Client with a custom TCP library?

Accepted Answer

Implement the IRedisNetLibAdapter interface to wrap your preferred TCP/IP library, then integrate it with the Redis client. The README provides the interface definition, and you can reference the INDY implementation in the source code as a guide.

Question 2

Does Delphi Redis Client support Redis clustering?

Accepted Answer

No, the library does not explicitly support Redis clustering in the current version. You would need to manage cluster connections manually, potentially using multiple client instances or a proxy, which adds complexity.

Question 3

What Delphi versions are supported by Delphi Redis Client?

Accepted Answer

Version 2 requires Delphi 10.1 Berlin or newer. For older versions like XE5 to 10 Seattle, you must use Version 1 from a separate branch, as noted in the README, which might lack updates and cross-platform features.

Question 4

How to implement pub/sub messaging with Delphi Redis Client?

Accepted Answer

Use the SUBSCRIBE method with channel arrays and a callback for messages, and PUBLISH to send messages. The IRedisClient interface includes these methods, but error handling and threading need to be managed externally in Delphi code.

Question 5

Delphi Redis Client vs other Delphi Redis libraries – which is better?

Accepted Answer

Delphi Redis Client stands out for full command coverage and cross-platform support, making it robust for most use cases. Compared to lighter alternatives, it's more comprehensive but may require more setup, especially if custom networking is needed.

Question 6

Can I use Delphi Redis Client for mobile app development?

Accepted Answer

Yes, it works on mobile platforms since the first version, and with Delphi 10.2 Tokyo, it supports Linux too, making it suitable for cross-platform mobile apps. However, ensure your TCP/IP library (e.g., INDY) is compatible with mobile targets.

Question 7

How to handle timeouts and errors in Delphi Redis Client?

Accepted Answer

Use the SetCommandTimeout method to configure timeouts, and check LastReadWasTimedOut via the adapter. Errors are typically handled through Delphi exceptions, as shown in the demo code, but robust error recovery may require additional implementation.
