Tuning the Blaze Engine

Tune the Blaze engine to adhere to big data processing requirements on the Blaze engine. When you tune the Blaze engine, the autotune command configures the Blaze advanced properties in the Hadoop connection.

The following table describes the Blaze properties that are tuned:

Property	Description	Value
infagrid.orch.scheduler.oop.container.pref.memory	The amount of memory that the Blaze engine uses to run tasklets.	5120
infagrid.orch.scheduler.oop.container.pref.vcore	The number of DTM instances that run on the Blaze engine.	4
infagrid.tasklet.dtm.buffer.block.size	The amount of buffer memory that a DTM instance uses to move a block of data in a tasklet.	6553600
* The tuned properties do not depend on the deployment type.
