  • Sizing memory used to store a table in an IMDC

    To learn how much memory an IMDC occupies, use the load_into_imdc function (which reports the number of IMDC rows in each partition) or the IMDC Memory Statistics API.

  • Checking available memory in a JVM

    To check the available memory in a JVM, use the available_memory_on_jvm function. Alternatively, you can access this information through the Java API.

  • Prompting Java garbage collection

    To prompt Java garbage collection, which returns unreferenced memory to the system, use either the gc_jvm function or the Java API call System.gc().
