|[trunk|https://github.com/apache/cassandra/compare/trunk...blerer:11207-trunk]|[utest|http://cassci.datastax.com/view/Dev/view/blerer/job/blerer-11207-trunk-testall/1/]|[dtest|http://cassci.datastax.com/view/Dev/view/blerer/job/blerer-11207-trunk-dtest/2/]|

The patch move the handling of the {{default_time_to_live}} in the {{Arguments}} class for CQL queries and in {{CassandraServer}} for Thrift. The patch also unify the behavior for Thrift and CQL ttl (Thrift use to reject ttl equals to zero).

The DTest PR is [here|https://github.com/riptano/cassandra-dtest/pull/831].

> I've created a table with a default TTL:

> CREATE TABLE testmna.ndr (
>     device_id text,
>     event_year text,
>     event_time timestamp,
>     active boolean,

>     AND compression = {'sstable_compression': 'org.apache.cassandra.io.compress.LZ4Compressor'}
>     AND dclocal_read_repair_chance = 0.1
>     AND default_time_to_live = 600
>     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';
> {code}
> When I insert data with a "runtime TTL" (INSERT ... USING TTL 86400) everything works as expected (ttl is set to 86400).
> But I can't insert data without TTL at runtime: INSERT ... USING TTL 0; does not work.
> Tested on C* 2.2.4, CentOS 7
