Interesting question and answer on HBase mailing list:
[…] is it feasible to use HBase table in “read-mostly” mode with trillions of rows, each contains small structured record (~200 bytes, ~15 fields). Does anybody know a successful case when tables with such number of rows are used with HBase?
My follow up questions:
- where is that data currently stored?
- how will you migrate it?
- if this is just what you estimate you’ll get, how soon will you reach these numbers?
