Subject Re: one column family but lots of tables
Date Thu, 22 Aug 2013 16:31:31 GMT
i suspect i might be misunderstanding some things. i thought column
families were related to packing things together physically. i do not yet
have any particular needs in that respect. and hearing about how hbase can
only have a few column families i figured i would just stick to 1 for now.

i do have many different datasets. to avoid namespace clashes i figured i
would put them in different tables. but now i suspect that approach was
wrong and i should use column qualifiers to keep them apart (within one
table and one column family).
