Data Volume

Tags: [, CSV file, database, delimited file]

Dear Team,  
I have to export bulk data (approx 1 billion) from Cassandra 2.0.14 via Talend. While I am using CQL (SELECT or COPY ) on cqlsh, it gets timeout or Cassandra is not properly response.   Can it be exported via Talend BD ? I have tested it for 50,000 records and it is working fine.  but I am not sure about  bulk extraction.  Can anyone suggest  ?

Thanks,
Sunil

Re: Data Volume

I am using Talend Big Data community version  6.2.1 and DSE  Cassandra 2.0.14 . Actually Biz is looking full data of Cassandra table in CSV files. but it is not possible using CQL (Select * from tablename) or COPY  command due huge data in Cassandra table.
