Abstract
Automatic clustering of a database table is disclosed. A method for automatic clustering of a database table includes receiving an indication that a data modification task has been executed on a table and determining whether the table is sufficiently clustered. The method includes, in response to determining the table is not sufficiently clustered, selecting one or more micro-partitions of the table to be reclustered. The method includes assigning each of the one or more micro-partitions to an execution node to be reclustered.
