Subject [jira] [Commented] (GIRAPH-906) out-of-core messages doesn't exist in Version: 1.1.0-SNAPSHOT.
Date Fri, 30 May 2014 14:47:02 GMT


Pavan Kumar commented on GIRAPH-906:

In GiraphConstants
  /** Enable out-of-core graph. */
  BooleanConfOption USE_OUT_OF_CORE_GRAPH =
      new BooleanConfOption("giraph.useOutOfCoreGraph", false,
          "Enable out-of-core graph.");

Is this what you are looking for?
Also if your program fails because of one message receiving excessive messages beating the
2^32 bytes limit, the error message contains helpful information of what to do next - which
is set the above option.

> 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.
