Hi All, I have a problem when writing streaming data to cassandra. Or existing product is on Oracle DB in which while wrtiting data, locks are maintained such that duplicates in the DB are avoided.
But as spark has parallel processing architecture, if more than 1 thread is trying to write same data i.e with same primary key, is there as any scope to created duplicates? If yes, how to address this problem either from spark or from cassandra side ? Thanks, Padma Ch
