Introducing Hindsight Memlake: serving 100M Memories at <100ms p99 on object storage

Hindsight released version 1.0 along with Memlake, a new storage engine that keeps agent memory in an object storage bucket the user controls and is built for a billion memories and more. Memlake is part of Hindsight Enterprise and already runs most of Hindsight Cloud, while open-source Hindsight keeps Postgres as the default. Hindsight says recall on Postgres slowed as banks grew, from 7.0 queries per second at 33,000 memories to 1.9 at 164,000 on a 4-vCPU primary. With Memlake, write cost no longer grows with bank size, p99 recall drops to 74 milliseconds once fully cached, and retrieval quality held steady.
