Migrating data from one table to other in cassandra -
i need migrate data 1 table other.
create table asses ( id uuid, toid text, name text, fbid text, primary key (id) ) coments = ''; create table basses ( id text, canid uuid, primary key (id) ) comment= '';
i need move data asses basses. data coulmns name , fbid should go id , data id should go canid.
i know joins not work here.
how make work?
the following copy commands should trick:
copy asses (name, id) 'file1.csv'; copy asses (fbid, id) 'file2.csv'; copy basses (id, canid) 'file1.csv'; copy basses (id, canid) 'file2.csv';
you can delete rows original table:
truncate asses;
hope helps.
