# What does this PR do? In short, provide a summary of what this PR does and why. Usually, the relevant context should be present in a linked issue. - [Currently redis as a kvstore is bugged, as the range method uses zrangebylex method. zrangebylex method is used when it is a sorted set but we are storing the value using .set method in the redis. This causes an error. Another issue is that zrangebylex method takes 3 args but only 2 are mentioned in the range method. This causes a runtime error. That method has been replaced with the current implementation in the PR ] Addresses issue (#520 ) ## Test Plan Please describe: - tests you ran to verify your changes with result summaries. - provide instructions so it can be reproduced. `python llama_stack/apis/agents/client.py localhost 8001 tools_llama_3_1 meta-llama/Llama-3.1-70B-Instruct` <img width="1711" alt="Screenshot 2024-11-25 at 2 59 55 PM" src="https://github.com/user-attachments/assets/c2551555-bc73-4427-b09b-c86d6deb2956"> <img width="634" alt="Screenshot 2024-11-25 at 3 00 33 PM" src="https://github.com/user-attachments/assets/a087718f-fc2a-424b-b096-4ecad08a07bf"> Have used redis in the run.yaml file as well for the persistence_store. Also enable_session_persistence turned to True for this test. Have also tested this in a jupyter notebook to make sure the current flow does not work through multiple turns in the same session. ## Sources Please link relevant resources if necessary. ## Before submitting - [ ] This PR fixes a typo or improves the docs (you can dismiss the other checks if that's the case). - [x] Ran pre-commit to handle lint / formatting issues. - [x] Read the [contributor guideline](https://github.com/meta-llama/llama-stack/blob/main/CONTRIBUTING.md), Pull Request section? - [ ] Updated relevant documentation. - [ ] Wrote necessary unit or integration tests.
