Review Comment:
Yeah didn't want to introduce an unwanted regression that would be hard to
roll back, can make this the static/default behavior if performance is good

> GobblinORCWriter self tune uses a number of metrics to determine how large
> their buffers should be for both its own internal buffer used for conversion
> and the native ORC writer buffer. However when there are very large record
> sizes (100s of kb) the buffers default max size (e.g. 1000) can still hold a
> very large amount of data. Observed performance would be hundreds of
> megabytes to even a gigabyte depending on the configured batch size maximums.
> We want a configuration to impose a maximum buffer max size so that large
> records in the buffer do not exceed the size of a stripe, so when it is added
> to the native ORC Writer, the native orc writer should be flushing its
> records and freeing the memory.
