Post: Memory

Sep 23, 2010

I understand that VoltDB will be limited to the available memory .. but what happen if my server has 4GB of memory but 8GB worth of data (or more) that needs to be loaded ? do I need to bring another server online or will it write some of the data on the disk ?

You need to have enough available RAM in your cluster to hold all of your data and indexes. VoltDB is in-memory and will not use disk to store data/index.
Keep in mind that some of the 4GB in your existing server will be consumed by the operating system and some must be set aside for Java.
