Described are a system, method, and computer program product for reconfiguring a data table for processing on a server cluster. The method includes extracting a data table from a relational database and determining whether the data table includes a column having a range of values with a uniform distribution. The method also includes, in response to determining that the data table includes the column, classifying the column as a candidate column for splitting the data table. The method further includes, in response to determining that the data table does not include the column, inserting an index column into the data table and classifying the index column as the candidate column. The method further includes splitting the data table based on the candidate column and distributing each subdivision to a node of the server cluster so as to cause the server cluster to collectively process the data table.
