Cool new work from my student Joshua.
Recent agentic systems (Claude Code, Codex, RLM, etc.) push context out of the prompt and into the environment (e.g., as files). This helps them maintain long-term knowledge about their goals and functionality.
๐จ While this is a good idea, we show a surprising result: systems that use external environments like this perform much better when given a small, fixed-size, in-context, agent-managed cache that "๐ฑ๐ฆ๐ฆ๐ฌ๐ด ๐ช๐ฏ๐ต๐ฐ" these environments.
๐ Our paper, ๐ฃ๐๐๐: ๐ ๐จ๐ฎ๐จ๐ฉ๐๐ข ๐๐ค๐ง ๐๐ช๐๐ก๐๐๐ฃ๐ ๐๐ฃ๐ ๐ข๐๐๐ฃ๐ฉ๐๐๐ฃ๐๐ฃ๐ ๐ฎ๐ป ๐ผ๐ฟ๐ถ๐ฒ๐ป๐๐ฎ๐๐ถ๐ผ๐ป ๐ฐ๐ฎ๐ฐ๐ต๐ฒ ๐๐ค๐ง ๐๐๐ ๐๐๐๐ฃ๐ฉ๐จ, introduces this idea.
Compared with strong baselines, including RAG, Compaction Agents, and SOTA prompt-learning frameworks, PEEK dominates the costโquality Pareto frontier: achieving 6.3โ34.0% in quality, with fewer iterations and lower cost.

Interesting article about #SemBench, a new benchmark for semantic AI operators; our Palimpsest system does super well on it!

It took three years to finish, but our follow-up to the 2006 "What Goes Around Comes Around" is finally out! Stonebraker and I examine the last 20 years in databases and discuss why relational databases SQL will continue to remain on top.

What are the most influential database papers of all time? Everyone has an opinion, but here's some data!
I ran PageRank on the VLDB/SIGMOD/CIDR citation graph. Search for a paper, view a specific year, or look up an author's most "influential" papers.
