Tuning graphloader JVM options
How to tune graphloader JVM options.
The DSE Graph Loader is written in Java and has some configurable JVM tuning in the
graphloader
script.
The default maximum heap size is 10G, generally a good heap size for appropriately sized
machine used with graphloader
. Two environment variables,
MAX_HEAP_SIZE
and HEAP_NEWSIZE
were added in DSE 5.0.5 and
later. graphloader
now calculates the values of these two environment
variables in the same manner
as the DSE database. If a particular
value is desired for either variable, the value can be set directly in the
graphloader
script.
