Check a table

Using cqlsh, the DESCRIBE TABLE command outputs the full details of a table, including all database objects the table contains. Use the output from the DESCRIBE command to recreate the table and all its components.

This command requires a keyspace. Ideally, you have also created a table, but it isn’t required.

DESCRIBE TABLE cycling.birthday_list;

If the table exists, the output includes all settings for tables and other objects including the default settings. If you use this output to recreate a table in another environment, verify that the settings are compatible.

CREATE TABLE cycling.birthday_list (
    cyclist_name text PRIMARY KEY,
    blist map<text, text>
) WITH additional_write_policy = '99PERCENTILE'
    AND 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 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 nodesync = {'enabled': 'true', 'incremental': 'true'}
    AND read_repair = 'BLOCKING'
    AND speculative_retry = '99PERCENTILE';
