Abstract

In some examples, in response to a join query to join a plurality of tables, a first processing engine retrieves tuples of a first table from a subset of objects of a data store, and adds content of the retrieved tuples to an in-memory table, where the objects are range partitioned across a plurality of processing engines based on respective ranges of values of at least one join attribute in the join query. The first processing engine retrieves, from the data store, tuples of a second table of the plurality of tables based on a range of values of the at least one join attribute in the retrieved tuples of the first table. The first processing engine performs an in-memory join of the plurality of tables based on the retrieved tuples of the second table and the in-memory table.
