I don’t think it is. The configuration reference specifies when a directive can be used multiple times. This is not the case with
Configuration reference doc: http://www.aerospike.com/docs/reference/configuration/#storage-engine
I just tried a config with two
storage-engine directives in a single namespace, and it seems to completely ignore the first one. I didn’t spot an error, but when inspecting the configuration using
asadm it displayed that the device is used as storage engine and
data-in-memory is false.
Why would you need both engines at the same time? Is the
data-in-memory setting not what you want?
