Abstract
A method includes: obtaining, by an inner table node that stores a portion of an inner table, a portion of an outer table from each of outer table nodes, and wherein a size of the outer table is less than a size of the inner table; reading, by the inner table node, the outer table by table joining threads or table joining processes of the inner table node; matching, by the table joining threads or the table joining processes, the outer table with the portion of the inner table stored at the inner table node; and outputting, by the inner table node, data from the outer table and the portion of the inner table that matches with each other.
