Pavan Kumar commented on GIRAPH-906:
------------------------------------

ah, sorry I was talking about bigdataio
giraph.useBigDataIOForMessages=true

as can be seen in ByteArrayVertexIdMessages#writeCurrentMessageBytes

that way all your messages can still be stored in memory.

but seems that you need out-of-core to persist to disk. I will leave it for some one else
to answer. Thanks.

> i was working with pregel and i noticed that when the jobs finish, They don't deallocate
memory. so i searched and knew that the latest version "Version: 1.1.0-SNAPSHOT" doesn't have
this problem so i  downloaded the latest version of giraph from apache giraph. the number
of produced message is a lot in my algorithm and because all of them are in memory, my ram
becomes full. so i searched the problem and found the out-of-core message config. i want to
set "giraph.useOutOfCoreMessages=true" but this config doesn't exixt in the latest version.
What;s the problem?
> Thanks.
