Abstract
Techniques are described herein for distributing distinct portions of a database object across the volatile memories of a plurality of nodes in a clustered database system. The techniques involve establishing a single database server instance located on a node in a multi-node cluster as a load-operation master for a particular data set. The load-operation master determines how the data set may be separated into chunks using a hash function. The load-operation master then broadcasts a small payload of consistency information to other database servers, so each database server may independently execute the hash function and independently load their respectively assigned chunks of data.
