Subject 1 vs. N CFs, dense vs. sparse CFs, flushing
Date Wed, 07 Jan 2015 17:10:04 GMT
Hi,

I recently came across this good thread about 1 vs. N ColumnFamilies, the
max recommended number of CFs, dense vs. sparse structure, etc. --
http://search-hadoop.com/m/TozMw1jqh262

This thread is from 2013. Even though people say HBase should handle more
than 3 CFs, the docs still recommend to stick to 2-3 CFs.  Is that still
the case?

See http://hbase.apache.org/book.html#number.of.cfs

Also, the thread talks about lumpy CFs and the fact that all CFs would have
to be flushed whenever any one of them triggers compaction..... but I
remember something being changed in this space a while back.  No?

Thanks,
Otis
