Applying Semantic Search on a Valkey Cache with valkey-py and valkey-search
19 Aug 2026 · Puget Sound Programming Python (PuPPy) · Seattle, WA
Using valkey-search for semantic search against a cache, demoed with valkey-py and valkey-search.
I gave this talk at Puget Sound Programming Python (PuPPy) in August 2026. The focus was semantic search against a cache as a way to save money on RAG pipeline calls and agentic spend, with a demo using valkey-py, the open source Python client, and valkey-search to search RGB color vectors by RGB ratio similarity. Semantic search support was added to the Valkey client as of March 2026. I learned about it at ValkeyConf and that’s how I found this topic!
This was a super lively crowd, even though it was over 80 degrees in the space! I ran out of fuel due to the heat at the end but overall had a great time, got a lot of laughs and positive feedback from the audience.
The video isn’t uploaded yet, but you can check out other PuPPy talks on the PuPPy YouTube channel.
