Abstract
The subject technology receives a set of values for a data set corresponding to a request for determining a Pearson correlation. The subject technology determines a number of rows from the data set. The subject technology determines a number of execution nodes to execute the request. The subject technology determines a set of shards of rows from the data set. The subject technology, for each shard from the set of shards, sends a particular user defined table function (UDTF), including a particular shard of rows, to a different execution node to perform a set of operations. The subject technology provides a set of output values of each particular UDTF corresponding to each shard from the set of shards in a second UDTF. The subject technology sends the second UDTF to a particular execution node to perform an aggregate operation using the set of output values of each particular UDTF.
