[jira] [Created] (PHOENIX-3887) Bulk export of large query result set

Chaitanya created PHOENIX-3887:
----------------------------------

             Summary: Bulk export of large query result set
                 Key: PHOENIX-3887
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3887
             Project: Phoenix
          Issue Type: Improvement
    Affects Versions: 4.8.0
            Reporter: Chaitanya
            Priority: Minor


Query results with large number of rows can not be consumed by a single JDBC connection.

To export these results as a CSV file either on a local filesystem or HDFS, we can connect by Spark / Hive to Phoenix but there can be a tool (or MR job) which can be implemented just like CsvBulkLoadTool or ./psql.py. This is a very common use case for big results. 

Similar functionality exists in Postgres via COPY command and in Redshift via UNLOAD command.
