Description
I will like to have following features in in cqlsh, I have made a patch to enable them as well.
1. Aliases.
2. Safe mode (prompt on delete,update,truncate,drop if safe_mode is true).
3. Press q to exit.
Its also shared here -> https://github.com/vineet01/cassandra/blob/trunk/new_features.txt
Example for aliases :-
cassandra@cqlsh> show
; <enter> ALIASES HOST SESSION VERSION
cassandra@cqlsh> show ALIASES ;
Aliases :>
now if you type dk and press <tab> it will auto complete it to "desc keyspace".
Adding an alias from shell :-
cassandra@cqlsh> alias slu=select * from login.user ;
Alias added successfully - sle:select * login.user ;
cassandra@cqlsh> show ALIASES ;
Aliases :>
cassandra@cqlsh> sle
Expanded alias to> select * from login.user ;
username | blacklisted | lastlogin | password
Adding an alias directly in file :-
aliases will be kept in same cqlshrc file.
[aliases]
dk = desc keyspaces;
sl = select * from
sle = select * from login.user ;
now if we type just "sle" it will autocomplete rest of it and show next options.
Example of safe mode :-
cassandra@cqlsh> truncate login.user ;
Are you sure you want to do this? (y/n) > n
Not performing any action.
cassandra@cqlsh> updatee login.user set password=null;
Are you sure you want to do this? (y/n) >
Not performing any action.
