-------------------------------------
Resolution: Fixed
> Select default buffer size for mini-batch preprocessor

> Key: MADLIB-1224
> URL: https://issues.apache.org/jira/browse/MADLIB-1224
> Project: Apache MADlib
> Issue Type: Improvement
> Components: Module: Utilities
> Reporter: Jingyi Mei
> Assignee: Jingyi Mei
> Priority: Major
> Fix For: v1.14

> As a follow up of https://issues.apache.org/jira/browse/MADLIB-1200
>
> In minibatch_preprocessor, we made buffer_size as an optional parameter. If
> it is not set, some default value will be assigned. Current considerations
> are:
> # Within segment, each cell has 1GB limit so that we can't put too many rows
> into one super row to exceed the limit
> # Among segments, data should be distributed as equally as possible to avoid
> data skew so that GPDB can work more efficiently.
