There are two ways to change the heap size in Elasticsearch. The easiest is to set an environment variable called ES_HEAP_SIZE. When the server process starts, it will read this environment variable and set the heap accordingly. As an example, you can set it via the command line as follows: export ES_HEAP_SIZE=10g
Alternatively, you can pass in the heap size via a command-line argument when starting the process, if that is easier for your setup: ./bin/elasticsearch -Xmx=10g -Xms=10g
Ensure that the min (Xms) and max (Xmx) sizes are the same to prevent the heap from resizing at runtime, a very costly process.
Generally, setting the ES_HEAP_SIZE environment variable is preferred over setting explicit -Xmx and -Xms values.
