[DISCUSSION] Should Carbon prohibit to use reserved words in database\table\col name

[Lion.X]

Ref: https://issues.apache.org/jira/browse/CARBONDATA-332

I agree with Harmeet's opinion that it is not a recommended and good approach for using system reserved words in creating data structures like database, tables or columns.

In hive and Oracle, using reserved words is prohibited.

pls give your opinions.

thx

agree.  reserved words should be prohibited in carbon.


regards
Jay

I think this is an issue of upper query processing layer instead of
Carbon. For example, Flink/Spark may have a different set of keywords, and
Carbon can't take a side.
