Hi all,
Recently I notice my current cluster data memory size is growing. But when I perform checking size for each table (show table status), they don't really match the size that the data memory consuming (retrieve the info from memoryusage table in ndbinfo database).
For example, my total table size are only 3GB but the data memory show 4GB. I knew there are some overhead for the datamemory, but can someone show me how to calculate this overhead as I need to calculate memory needed for the incoming table to be added. Just afraid my current datamemory are unable to support.
Many thanks for helping
