To Share or Not to Share?

Summary: Shows a trade-off between work sharing and parallelism in multi-core DBs, where sharing can serialize on the critical path and hurt performance. Introduces a lightweight model and prototype engine for selective sharing, achieving up to 2.5x gains and ~20% average improvement. (summarized by gpt-5-nano on Feb 09 2026)
