Swap Space Requirements
Vertica requires at least 2 GB swap partition regardless of the amount of RAM installed on your system. The installer reports this issue with identifier S0180.
For typical installations Vertica recommends that you partition your system with a 2GB primary partition for swap regardless of the amount of installed RAM. Larger swap space is acceptable, but unnecessary.
Do not place a swap file on a disk containing the Vertica data files. If a host has only two disks (boot and data), put the swap file on the boot disk.
If you do not have at least a 2 GB swap partition then you may experience performance issues when running Vertica.
You typically define the swap partition when you install Linux. See your platform’s documentation for details on configuring the swap partition.
