Re: How to limit a single row being filled with millions of columus?

There are a config hbase.table.max.rowsize but only used for user get/scan. It will throw RowTooBigException when you scan a big row with millions of columns. But it doesn't work for compact. If i am not wrong, there are not a way to prevent a single row being filled with millions of columns.

HBase replication supported both of them. You can use add_peer or set_peer_tableCFs to config specific tables for specific peers.
