Hi bharat, you are talking about Cassandra 1.2.5 Does it fit Cassandra 2.1? Were there any significant changes to SSTable format and layout? Thank you, article is interesting.
Hi jacob <jacob.rho...@me.com>, HBase does it for example. http://hbase.apache.org/book.html#_hfile_format_2 It would be great to give general ideas. It could help to understand schema design problems. You start to understand better how Cassandra scans data how you can utilize its power. 2015-04-01 5:39 GMT+02:00 Bharatendra Boddu <bharatend...@gmail.com>: > Some time back I created a blog article about the SSTable storage format > with some code references. > > Cassandra: SSTable Storage Format > <http://distributeddatastore.blogspot.com/2013/08/cassandra-sstable-storage-format.html> > > - bharat > > On Mon, Mar 30, 2015 at 5:24 PM, Jacob Rhoden <jacob.rho...@me.com> wrote: > >> Yes updating code and documentation can sometimes be annoying, you would >> only ever maintain both if it were important.
