@prashadi I created a sample Patient model locally with three fields
@Table
public class Patient {
@PrimaryKey
private UUID id;
private String name;
private Date birthDate;
getters, setters, constructors...
and attached it to a spring data repository with cassandra configuration’s schema action set to drop all and create only known tables on application startup.
This gave me the following schema,
cqlsh> describe cassandra.patient
CREATE TABLE cassandra.patient (
id uuid PRIMARY KEY,
birthdate timestamp,
name 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 = 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 = '99PERCENTILE';
So it seems spring data cassandra treats each field as a separate column.
