By default, the DIH converts incoming DREADD
index actions, which contain a reference location of the file to index, to DREADDDATA
index actions, which send the data directly. You can use the PreserveDREADD
configuration parameter if you want DIH to forward the DREADD
action directly.
In this case, all the child servers must be able to access the file system that contains the original IDX file, using the file path specified in the DREADD
index action. This option can reduce network load, because DIH sends only the path to the IDX file, rather than streaming all the data.
You can use this parameter only in simple mirror or non-mirror mode.
