> This proposal aims to introduce a new micro benchmark “LargeRowBenchmark” to
> check Spark's support/performance on large-row dataframes. A large-row
> dataframe is the one with MB-size cells (think about online chatting
> records). Different from existing WideTableBenchmark where the dataframe has
> more-than-normal columns, this benchmark focuses on dataframes with normal
> amount of columns but larger-than-usual cells. The purpose of this proposal
> is to add large-row dataframe to future performance regression check.
