Description
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.
