fmcquillan99 edited a comment on issue #422: Correlation: Process deconstruction in chunks for grouping URL: https://github.com/apache/madlib/pull/422#issuecomment-510581269 ``` n_groups_per_run (optional) <dd>INTEGER, default: 10. Number of groups to deconstruct at a time. This parameter value is ignored if grouping_cols is not specified. Processing large number of groups together may have memory/stack/execution time issues. This parameter should be used with caution. The number of groups that can be processed together is a function of various database settings.</dd> </dl> ``` This is hard to understand. Can we give guidance on when to change it from the default? Need to make the trade off clear. E.g., increasing does x at the expense of y decreasing does a at the expense of b Also I don't know what to call it yet since I'm not 100% sure what it does.
