cassandra - Difference between Thrift and CQL 3 Columns/Rows -


at cassandra summit, mentioned thrift , cql 3 have subtle differences in definitions of columns , rows. google hasn't helped me understand difference. information can find metadata different, , such, shouldn't mix thrift , cql.

  1. what subtle difference (i've read bit metadata representations...)?
  2. in way break compatibility?
  3. why change better?

i'm happy read docs me, i've been unable find related topic.

here's reading path taught follow answer same question:

  1. intro apache cassandra 1.2
  2. a thrift cql3 upgrade guide
  3. cql3 cassandra experts : datastax
  4. does cql support dynamic columns / wide rows?
