Heimdall Data:自動 Cache RDBMS 資料增加效能

看到 AWS 的「Automating SQL Caching for Amazon ElastiCache and Amazon RDS」這篇裡面介紹了 Heimdall Data – SQL caching and performance optimization 這個產品。

從官網的介紹也可以看出來是另外疊一層 proxy,但自動幫你處理 cache invalidation 的問題:

But what makes Heimdall Data unique in industry is its auto-cache AND auto-invalidation capability. Our machine learning algorithms determine what queries to cache while invalidating to ensure maximum performance and data integrity.

看起來支援了四個蠻常見的 RDBMS:

Heimdall Data supports most all relational database (e.g. MySQL, Postgres, Amazon RDS, Oracle, SQL Server, MariaDB).

看起來是一個花錢直接買效能的方案... 不過 cache invalidation 的部分不知道要怎麼跨機器做,在 FAQ 沒看到 cluster 情況下會怎麼解決。
