Documentation/Examples for DataStax java-driver
Are there any documentation/examples available for DataStax java-driver besides what's in the GitHub repo?

@Edward. I completely agree. I was just explaining my original rationale in posting to this mailing list.
Maybe it's time to start a dedicated DataStax java-driver mailing list.

@Drew
This list is for cassandra users. Since the DataStax java-driver is
not actually part of Cassandra. If every user comes here to talk about
their driver/orm/problems they are having with code that is not part
of cassandra this list will get noisy.
IMHO client-dev is the right place for these type of topics.
Occasionally a cross post makes sense.

As mentioned previously the code comes with some detailed Javadoc. But
you're right as well that Javadoc isn't enough. At DataStax we're currently
working on a documentation for our drivers that will be as detailed as the
one we provide for Apache Cassandra.
Meanwhile we'll also add more code samples to make it easier for newcomers.

That's kinda what I was thinking to, just wanted to see if there's a built-in way.

Re: Documentation/Examples for DataStax java-driver

The API allows to build your own batch through building a query I do not
use that, neither counter columns. I do not build a query, I create a CQL
like:
String batchInsert = "BEGIN BATCH " +
"INSERT INTO xyz( a, b, c, " +
" VALUES ( ?, ?, ?) " +
"INSERT INTO def(a, b, ,c," +
" VALUES ( ?, ?, ?) " +
"APPLY BATCH";
PreparedStatement prBatchInsert = session.prepare(batchInsert);
statement.setConsistencyLevel(ConsistencyLevel.QUORUM);
BoundStatement query = prBatchInsert.bind(1,2,3, 1,2,3);
session.execute(query);
I got session through this:
cluster =
Cluster.builder().addContactPoint(getInitParameter("cassandraCluster"))
.withRetryPolicy(DowngradingConsistencyRetryPolicy.INSTANCE ).build();
session = cluster.connect(getInitParameter("keyspace"));
I have queries that i have begin unlogged batch instead of begin batch
Hopefully it helps

@Shahryar/Gabriel
I know the source code is nicely documented, but I couldn't find much info on:
1. Creating/submitting atomic/non-atomic batches.
2. Handling Counter columns
Do you have any examples for that?
@Edward
I was under impression that client-dev mailing list was to be used by the developers/committers of the client libs and each client has their own mailing list such as hector, but I'm not sure there exist a mailing list for DataStax's java-driver.

Just an FYI. More appropriate for the client-dev list.

Code has good documentation and also the example module has enough

Source code has enough documentation in it, apparently this is how they do
it with new stuff. Start with Custer class, it tells you how to write. If
you still had problem let me know, I can give you sample code.
