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.
