Table redistribution in distributed databases

A system comprising:

• computer circuitry configured to perform operations comprising:
• determining that a redistribution of a plurality of tables is required in a distributed in-memory database, the distributed in-memory database comprising a plurality of tables located on a plurality of distributed nodes;
• generating, based at least in part on a set of table redistribution parameters, a table redistribution plan comprising redistribution of a table of the plurality of tables, the set of table redistribution parameters comprising a grouping parameter indicating at least one other table with which the table should be collocated;
• and
• executing the table redistribution plan, the executing comprising moving the table from a first node of the plurality of distributed nodes to a second node of the plurality of distributed nodes.

A computer-implemented method comprising:

• and
• executing the table redistribution plan, the executing comprising moving the table from a first node of the plurality of distributed nodes to a second node of the plurality of distributed nodes.
