Class LocalDateTimeCodec

java.lang.Object

com.datastax.driver.core.TypeCodec<LocalDateTime>

com.datastax.driver.extras.codecs.jdk8.LocalDateTimeCodec

public class LocalDateTimeCodec
extends TypeCodec<LocalDateTime>

TypeCodec that maps LocalDateTime to CQL timestamp, allowing the setting and retrieval of timestamp columns as LocalDateTime instances.

IMPORTANT

1) The default timestamp formatter used by this codec produces CQL literals that may include milliseconds. This literal format is incompatible with Cassandra < 2.0.9.

2) Even if the ISO-8601 standard accepts timestamps with nanosecond precision, Cassandra timestamps have millisecond precision; therefore, any sub-millisecond value set on a LocalDateTime will be lost when persisted to Cassandra.
