Abstract
The technology described herein is directed towards balancing workload between cluster nodes via redistribution of metadata data structures (e.g., memory tables corresponding to directory table partitions). Workload-related information of a node and its partitions' primary memory tables usage is measured, and if sufficiently high, causes a move of a highly-accessed memory table (corresponding to high workload on a first node) from the first node to a second node that has less workload. The second node can contain a backup (e.g., shallow) memory table to the primary node, whereby the move can be a logical move that transforms the backup memory table into a new instance of the primary memory table on the second node. The first node's primary memory table can be deflated into a backup table on the first node that backs up the new instance of the primary table on the second node.
