There is no automatic indexing in Cassandra. There are secondary indexes, but not for these cases. You could use a solution like DSE, to get data automatically indexed on solr, in each node, as soon as data comes. Then you could do such a query on solr. If the query can be slow, you could run a MR job over all rows, filtering the ones you want. []s From: user@cassandra.apache.org Subject: Re:query by column size
Greetings, I have one column family with 10 columns, one of the column we store xml/json. Is there a way I can query that column where size > 50kb ? assuming I have index on that column. thanks CV.
