Hello,

try to run with debug=3 in kamailio.cfg and see if you get more hints why the cass_retrieve() is returning negative code.

Cheers,
Daniel

Greetings Lists. 

I am having hard time trying to use ndb_cassandra with kamailio. I have successfully complied the module and kamailio runs without any error. 

Below is relevant snippet. 

loadmodule "ndb_cassandra.so"

modparam("ndb_cassandra", "host", "192.168.0.103")

modparam("ndb_cassandra", "port", 9160)

        $var(keyspace) = 'kamailio';

        $var(column_family) = 'numbers_directory';

        $var(key) = 15;

        $var(column) = 'number';

        xlog("L_INFO", "Valus to fetch are $var(keyspace), $var(column_family), $var(key), $var(column) \n");

        if (cass_retrieve("$var(keyspace)", "$var(column_family)", "$var(key)", "prefix", "$var(val_read)") > 0) {

                xlog("L_INFO", " ===== ndb_cassandra. Sucess while reading from Cassandra. val_read: \"$var(val_read)\"\n");

        } else {

                xlog("L_INFO", " ===== ndb_cassandra. Error while reading from Cassandra \n");

        }

Cassandra Table Structure. 

cqlsh:kamailio> describe numbers_directory;

CREATE TABLE kamailio.numbers_directory (

    id int PRIMARY KEY,

    description text,

    number text

) WITH bloom_filter_fp_chance = 0.01

    AND caching = '{"keys":"ALL", "rows_per_partition":"NONE"}'

    AND comment = ''

    AND compaction = {'class': 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy'}

    AND compression = {'sstable_compression': 'org.apache.cassandra.io.compress.LZ4Compressor'}

    AND dclocal_read_repair_chance = 0.1

    AND default_time_to_live = 0

    AND gc_grace_seconds = 864000

    AND max_index_interval = 2048

    AND memtable_flush_period_in_ms = 0

    AND min_index_interval = 128

    AND read_repair_chance = 0.0

    AND speculative_retry = '99.0PERCENTILE';

cqlsh:kamailio> select * from numbers_directory;

 id | description | number

----+-------------+-----------

 15 |        null | 212456789

When i make a call i get this in logs. 

Jul  1 19:10:42 debian ./kamailio[8142]: INFO: <script>: Valus to fetch are kamailio, numbers_directory, 15, number

Jul  1 19:10:42 debian ./kamailio[8142]: INFO: <script>:  ===== ndb_cassandra. Error while reading from Cassandra

I am stuck at this. Does anybody able to use kamailio with cassandra or can share their configuration?

Any pointer on this is much appreciated. 

Best Regards, 

Aqs Younas
