----------------------------------
Summary: SQL processors may generate Avro-incompatible column names
Key: NIFI-5563
URL: https://issues.apache.org/jira/browse/NIFI-5563
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Reporter: Matt Burgess
Although the "Convert Names for Avro" property in such processors as ExecuteQL
replaces non-Avro characters with underscores, it doesn't validate/alter the
names to ensure they are Avro compatible. For example, SELECT 1 may give a
column name of 1, but Avro names have to start with one of [A-Za-z_]. We need
to check for that and prefix an underscore if the name doesn't start with one
of those characters.
