Do we any web link that gives details about all the possibile configurations 
and properties ?



Thanks

Subject: [EXTERNAL] Re: How to Change memory setting for a unifier?

Hi Raja,

To set the memory for the unifier you would use the port to identify the 
unifier, so something like

dt.operator.oper1.port.port1.unifier.MEMORY_MB

or use the setUnifierAttribute in DAG if setting it from java.

Thanks

Hi,

Can someone please help me with configuration property on how to increase 
memory setting for Unifier?

I am using the below way, to increase the memory for Application Master and 
opertors of a DAG:

<property>
    <name>dt.attr.MASTER_MEMORY_MB</name>
    <value>10240</value>
</property>

<property>
    <name>dt.operator.*.attr.MEMORY_MB</name>
    <value>10240</value>
</property>


UseCase/Scenario:

I am having an apex application that reads from Kafka in 3 partitions with the 
setting “ONE_TO_MANY”, and sends the messages to following operators. But, the 
problem is, even though the messages are being read thru multiple parititons, 
but I see a unifier operation happening after the messages read in multiple 
kafka partitions. Which is becoming a bottle nect with the number of increase 
in the number of messages being floated.

I have configured the memory all the operators to 10GB, with above given 
setting, but, the unifier which has been cropped up, was taking only 2GB by 
default, and failing with heap space problems.

Hence I wish to increase the memory for the unifier.

Thanks a lot in advance.


Regards,
Raja.
