    Description

      As per SQL standard. Hive currently uses `` (backticks). Default will continue being backticks, but we will support identifiers within double quotation via configuration parameter.

      This issue will also extends support for arbitrary char sequences, e.g., containing ~ ! @ # $ % ^ & * () , < >, in database and table names. Currently, special characters are only supported for column names.
