Subject Re: Max Buffer Size Reached
Date Sat, 06 Feb 2016 02:28:22 GMT
Excuse my basic questions, when you say we are you reference Drill coders?
So what is Integer.MAX_VALUE bytes? Is that a query time setting? Drillbit
setting? Is it editable?  How does that value get interpreted for complex
data types (objects and arrays).

Not only would the column be helpful, but the source file as well.  ( if
this is an individual record issue....or is this a cumulative error where
the max size of the sum of the length of multiple records of a column is at
issue).


Thoughts on how as a user I could address this in my dataset?

Thanks!
