'default_time_to_live' is used to set the default expiration time (“TTL”) in seconds for a table.
Example
CREATE TABLE IF NOT EXISTS cassandratutorial.employee (
id INT PRIMARY KEY,
firstName VARCHAR,
lastName VARCHAR,
age int,
) WITH default_time_to_live=3600;
cqlsh> CREATE TABLE IF NOT EXISTS cassandratutorial.employee (
... id INT PRIMARY KEY,
... firstName VARCHAR,
... lastName VARCHAR,
... age int,
... ) WITH default_time_to_live=3600;
cqlsh>
cqlsh> DESCRIBE cassandratutorial.employee;
CREATE TABLE cassandratutorial.employee (
id int PRIMARY KEY,
age int,
firstname text,
lastname 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', 'max_threshold': '32', 'min_threshold': '4'}
AND compression = {'chunk_length_in_kb': '64', 'class': 'org.apache.cassandra.io.compress.LZ4Compressor'}
AND crc_check_chance = 1.0
AND dclocal_read_repair_chance = 0.1
AND default_time_to_live = 3600
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 = '99PERCENTILE';
