Jason Brown commented on CASSANDRA-4924:
----------------------------------------
My two cents: The initial impact of trying out the new feature (cql3), and not
being to compare it with something I already know (cassandra-cli) is a little
confusing. I think Sylvain is onto something when, in the other ticket, he
mentions this may be a documentation issue, but where would a new cql3 user
(experienced with the old-school way) go to figure out what happened to their
shiny new cql3 data?
While it's a little bit more work of supporting thrift, it might be worth it to
ensure a smoother on-ramp for cql3. Perhaps Aaron's idea of a config help lower
the barrier to exit from thrift for users.
Personally, I'd just want the cli, and clients like astyanax/hector, to be able
to describe_keyspace to show me the cql3 table exists, and reads would be nice,
too, so I could confirm the cql3 data. Anything else is a freebie when trying
to on-ramp to cql3.
> Make CQL 3 data accessible via thrift.
> --------------------------------------
>
> Key: CASSANDRA-4924
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4924
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 1.2.0
> Reporter: amorton
>
> Following the changes from CASSANDRA-4377 data created using CQL 3 is not
> visible via the thrift interface.
> This goes against the spirit of many comments by the project that "the thrift
> API is not going away". These statements and ones such as "Internally, both
> CQL3 and thrift use the same storage engine, so all future improvements to
> this engine will impact both of them equally."
> (http://www.datastax.com/dev/blog/thrift-to-cql3) and the CQL3 and thrift
> examples given here
> http://www.datastax.com/dev/blog/cql3-for-cassandra-experts gave the
> impression CQL 3 was a layer on top of the core storage engine. It now
> appears to be an incompatible format change.
> It makes it impossible to explain to existing using users how CQL 3 stores
> it's data.
> It also creates an all or nothing approach to trying CQL 3.
> My request is to make all data written by CQL 3 readable via the thrift API.
> An example of using the current 1.2 trunk is below:
> {noformat}
> cqlsh:cass_college> CREATE TABLE UserTweets
> ... (
> ... tweet_id bigint,
> ... user_name text,
> ... body text,
> ... timestamp timestamp,
> ... PRIMARY KEY (user_name, tweet_id)
> ... );
> cqlsh:cass_college> INSERT INTO
> ... UserTweets
> ... (tweet_id, body, user_name, timestamp)
> ... VALUES
> ... (1, 'The Tweet', 'fred', 1352150816917);
> cqlsh:cass_college>
> cqlsh:cass_college>
> cqlsh:cass_college> select * from UserTweets;
> user_name | tweet_id | body | timestamp
> -----------+----------+-----------+--------------------------
> fred | 1 | The Tweet | 2012-11-06 10:26:56+1300
> {noformat}
> and in the CLI
> {noformat}
> [default@cass_college] show schema;
> create keyspace cass_college
> with placement_strategy = 'SimpleStrategy'
> and strategy_options = {replication_factor : 3}
> and durable_writes = true;
> use cass_college;
> [default@cass_college] list UserTweets;
> UserTweets not found in current keyspace.
> [default@cass_college]
> {noformat}
