With logstash 2.3.1 jdbc input plugin, the column names in the result are converted to lowercase.
For e.g - column callDistributorTimeOfCall was appearing same in logstash-2.1.1 where as with logstash-2.3.1 it appears as calldistributortimeofcall.
This is resulting in unnecessary extra fields, apart from the ones defined in index template, and the reporting is going for a toss.
Also when I reconfigured the whole stuff, by converting the ES index fields to lower case, the field types and other parameters like "index": "not_analyzed" are not respected.
Any one has experienced this problem?
