Abstract
A database management system includes a cluster of nodes over which a columnar database has been sharded into shards to which the nodes are subscribed. Source nodes of the cluster store up-to-date metadata objects for the shards, and target nodes of the cluster storing out-of-date metadata objects for the shards. A coordinator node initiates a parallel batch metadata transfer update process in which the out-of-date metadata objects at the target nodes are updated in parallel from the up-to-date metadata objects at the source nodes. The coordinator node can determine pairs of source nodes and target nodes; the source node and the target node of each pair respectively store an up-to-date metadata object and an out-of-date metadata object for a same shard.
