------------------------------------
Summary: Support CarbonCli tool for data summary
Key: CARBONDATA-2916
URL: https://issues.apache.org/jira/browse/CARBONDATA-2916
Project: CarbonData
Issue Type: New Feature
Reporter: Jacky Li
When I am tuning carbon performance, very often that I want to check the
metadata in carbon files without launching spark shell or sql. In order to do
that, I am writing a tool to print metadata information of a given data folder.
Currently, I am planning to do like this:
usage: CarbonCli
-a,--all print all information
-b,--tblProperties print table properties
-c,--column <column name> column to print statistics
-cmd <command name> command to execute, supported commands are:
summary
-d,--detailSize print each blocklet size
-h,--help print this message
-m,--showSegment print segment information
-p,--path <path> the path which contains carbondata files,
nested folder is supported
-s,--schema print the schema
In first phase, I think “summary” command is high priority, and developers can
add more command in the future.
