Valcache for Datomic On-Prem

09 October 2018

Note

Datomic On-Prem is now called Datomic Pro. This post uses the original name.

Everything gets better when data moves closer to processing. Datomic can extensively cache its immutable data without concern for coordination or invalidation. With the 'valcache' feature in today’s Datomic On-Prem release you can use your local SSDs as large, durable per-process caches, on both transactors and peers. Valcache can improve performance, reduce the read load on storage and stay hot across process restarts.
