May was a packed month at Readyset.

We published a new case study showing how Lemit scaled MySQL to over 109,000 queries per second with sub-1ms cached latency and zero application changes. On the product side, we shipped native MCP support, PostgreSQL group commit, and the new UNTIL WRITE caching policy for automatic query acceleration. We also wrapped up Marcelo Altmann's MySQL replication internals series, published new performance and engineering deep dives, and shared recaps from Percona Live and Web Summit.
