Aaron McCurry commented on BLUR-221:
------------------------------------
So this might be a little bit complex for just plain args into the command.
tablename is required
family is required (except for when the column a user wants is a built-in
column like rowid or recordid)
column name is required
starts with could be empty or blank or null and it would start at the beginning
size should probably be fixed internally to something like 100 or 1000
>From a usability stand point I think that a user should be able to minimize
>the amount of typing they have to do to make the call.
For example I think that this should be a couple of examples of how to use the
command:
#then this starts displaying all the row ids in the system
terms testtable rowid
#This command starts displaying all the terms for column "col1" in family
"fam0"in the system
terms testtable fam0.col1
#This command starts displaying all the terms for column "col1" in family
"fam0"in the system starting at "value1"
terms testtable fam0.col1 -s value1
#This command starts displaying all the terms for column "col1" in family
"fam0"in the system starting at "value1" fetch 100 then exit
terms testtable fam0.col1 -s value1 -n 100
So obviously you are going to have to do some parsing of the column name to
break it up into family and column name. Also I would suggest using the
commons-cli to parse the commands, for an example look at the create table
command.
The last bit of the command will be a bit more complex, if you use the "query"
command you will notice a paging mechanism that displays a page at a time and
allows the user to quit or exit the commands output. So if the output is
greater than a single page of results you should page, hopefully the code
that's there can guide you.
Let me know if you have more questions.
