JVM heap size
editJVM heap size
editECE uses default JVM heap sizes for services that work for testing. When you install ECE
specify the recommended JVM heap sizes with --memory-settings JVM_SETTINGS parameter.
For any topology, we recommend:
| Service | JVM Heap Size (Xms and Xmx) |
|---|---|
|
1 GB |
|
4 GB |
|
4 GB |
|
1 GB |
|
4 GB |
|
4 GB |
Other JVM heap sizes can be left at their defaults. For the OpenJDK 8 in use by ECE this means processes will have 1/4 of the host machines memory as the maximum heap size.
