Understanding and Optimizing Database Pushdown on Disaggregated Storage

The authors' abstract

This is the paper's own summary, in the paper's own words. It is dense on purpose — abstracts are written to compress.

Database pushdown is a widely adopted technique under compute-storage disaggregation. The rising network and I/O speeds, coupled with stagnated compute and memory subsystems of a disaggregated storage architecture in the past decade, render state-of-the-art policy-driven pushdown designs ineffective. This is because the query performance bottleneck has shifted from network and I/O to compute, where computing power at the storage layer becomes scarce.
