Subject MAX_FIELD_LENGTH Validation doesn't allow queries over large strings
Date Wed, 30 Aug 2017 01:27:20 GMT
Hi,


We are working with a dataset with columns of large Strings on it, and we
are having the error "UNSUPPORTED_OPERATION ERROR: Trying to write
something big in a column columnIndex 0 Limit 65536 Failure while reading
file ..."


There is a validation on FieldVarCharOutput.java
<https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/store/easy/text/compliant/FieldVarCharOutput.java>
using
MAX_FIELD_LENGTH

Why this validation use this specific value MAX_FIELD_LENGTH = 1024 * 64?
Is possible to handle large Strings like as used to represent wkt
Geometries?

Regards!
