Abstract: The present disclosure relates to example table connection methods, devices, and systems. In one example method, data that is sent by a coordinator node and that is in a first target column in a first data table is stored by a data node in a local memory. The data node receives a table connection request. When first data in the first target column is the same as second data in a second target column, the data node connects data in a row in which the first data is located to data in a row in which the second data is located. The data node sends a connection result to the coordinator node.
