Compund/Composite column names
Hi All,
I am trying to use compound primary key column name and i am referring to:
http://www.datastax.com/dev/blog/whats-new-in-cql-3-0
As mentioned on this example, i tried to create a column family containing compound primary key (one or more) as:
CREATE TABLE altercations (
instigator text,
started_at timestamp,
ships_destroyed int,
energy_used float,
alliance_involvement boolean,
PRIMARY KEY (instigator,started_at,ships_destroyed)
);
And i am getting:
**********************************************************************
TSocket read 0 bytes
cqlsh:testcomp>
**********************************************************************
Then followed by insert and select statements giving me following errors:
********************************************************************************************************************************************
cqlsh:testcomp> INSERT INTO altercations (instigator, started_at, ships_destroyed,
... energy_used, alliance_involvement)
... VALUES ('Jayne Cobb', '2012-07-23', 2, 4.6, 'false');
TSocket read 0 bytes
cqlsh:testcomp> select * from altercations;

Any idea?

Just verified, basically column family itself is not getting created on very first place, as reconnecting cql client again does not show it.

Nothing on server log. Only difference is i tried to create a compound key using 3 composite columns, whereas example on website is with 2.
When i try to connect via cassandra-cli, i am able to connect but this column family is not available.
So i guess, this might be an issue with CQL3, not with cassandra server?

Feel free to open a ticket with steps to reproduce. We can certainly throw a

Feel free to open a ticket with steps to reproduce. We can certainly throw a

Re: Compund/Composite column names
Posted by Jonathan Ellis <jb...@gmail.com>.
You are confusing client-side and server-side validation. The server
should validate thrift inserts against cql3 table to prevent
egregiously malformed data, per the discussion on [1]. (Of course
even on the server we're limited to "this bunch of bytes here could
probably be an int" but that should be enough to prevent AIOBE.)
So if rc1 has validation problems, we should be able to fix that. (An
example with the cli would be easiest to address.)
[1] https://issues.apache.org/jira/browse/CASSANDRA-4377?focusedCommentId=13446499&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13446499

Re: Compund/Composite column names
Posted by Edward Capriolo <ed...@gmail.com>.
This was discussed in one of the tickets. The problem is that CQL3's sparse
tables is it has different metadata that has NOT been added to thrift's
CFMetaData. Thus thrift is unaware of exactly how to verify the insert.
Originally it was made impossible for thrift to see a sparse table (but
that restriction has been lifted) it seems. It is probably a bad idea to
thrift insert into a sparse table until Cassandra does not have two
distinct sources of meta information.

FYI -- I'm still seeing this on 1.2-beta1.
If you create a table via CQL, then insert into it (via Java API) with
an incorrect number of components. The insert works, but select *
from CQL results in a TSocket read error.
I showed this in the webinar last week, just in case people ran into
it. It would be great to translate the ArrayIndexOutofBoundsException
from the server side into something meaningful in cqlsh to help people
diagnose the problem. (a regular user probably doesn't have access to
the server-side logs)

FYI -- I'm still seeing this on 1.2-beta1.
If you create a table via CQL, then insert into it (via Java API) with
an incorrect number of components. The insert works, but select *
from CQL results in a TSocket read error.
I showed this in the webinar last week, just in case people ran into
it. It would be great to translate the ArrayIndexOutofBoundsException
from the server side into something meaningful in cqlsh to help people
diagnose the problem. (a regular user probably doesn't have access to
the server-side logs)
You can see it at minute 41 in the video from the webinar:

Re: Compund/Composite column names
Posted by Jonathan Ellis <jb...@gmail.com>.
Sounds like you're running into the keyspace drop bug. It's "mostly" fixed
in 1.1.5 but you might need the latest from 1.1 branch. 1.1.6 will be
released soon with the final fix.

Re: Compund/Composite column names
Posted by Vivek Mishra <vi...@yahoo.com>.
Ok. I am able to understand the problem now. Issue is:
If i create a column family altercations as:
**********************************************************************************************************8
CREATE TABLE altercations (
instigator text,
started_at timestamp,
ships_destroyed int,
energy_used float,
alliance_involvement boolean,
PRIMARY KEY (instigator,started_at,ships_destroyed)
);
/
INSERT INTO altercations (instigator, started_at, ships_destroyed,
energy_used, alliance_involvement)
VALUES ('Jayne Cobb', '2012-07-23', 2, 4.6, 'false');
*********************************************************************************************************************
It works!
But if i create a column family with compound primary key with 2 composite column as:
*********************************************************************************************************************
CREATE TABLE altercations (
instigator text,
started_at timestamp,
ships_destroyed int,
energy_used float,
alliance_involvement boolean,
PRIMARY KEY (instigator,started_at)
);
*********************************************************************************************************************
and Then drop this column family:
*********************************************************************************************************************
drop columnfamily altercations;
*********************************************************************************************************************
and then try to create same one with primary compound key with 3 composite column:
*********************************************************************************************************************
CREATE TABLE altercations (
instigator text,
started_at timestamp,
ships_destroyed int,
energy_used float,
alliance_involvement boolean,
PRIMARY KEY (instigator,started_at,ships_destroyed)
);
*********************************************************************************************************************
it gives me error: "TSocket read 0 bytes"
Rest, as no column family is created, so nothing onwards will work.
Is this an issue?
