Package io.debezium.time

Class NanoTimestamp

  • public class NanoTimestamp
extends Object
    A utility for converting various Java time representations into the signed INT64 number of nanoseconds past epoch, and for defining a Kafka Connect Schema for timestamp values with no timezone information.

      • builder

        public static org.apache.kafka.connect.data.SchemaBuilder builder()
        Returns a SchemaBuilder for a NanoTimestamp. The resulting schema will describe a field with the "io.debezium.time.NanoTimestamp" as the name and INT64 for the literal type storing the number of nanoseconds past midnight.

        You can use the resulting SchemaBuilder to set or override additional schema settings such as required/optional, default value, and documentation.

        Returns:
        the schema builder

      • schema

        public static org.apache.kafka.connect.data.Schema schema()
        Returns a Schema for a NanoTimestamp but with all other default Schema settings. The schema describes a field with the "io.debezium.time.NanoTimestamp" as the name and INT64 for the literal type storing the number of nanoseconds past midnight.
        Returns:
        the schema

      • toEpochNanos

        public static long toEpochNanos​(Object value,
                                TemporalAdjuster adjuster)
        Get the number of nanoseconds past epoch of the given LocalDateTime, LocalDate, LocalTime, Date, Date, Time, or Timestamp.
        Parameters:
        value - the local or SQL date, time, or timestamp value; may not be null
        adjuster - the optional component that adjusts the local date value before obtaining the epoch day; may be null if no adjustment is necessary
        Returns:
        the epoch nanoseconds
        Throws:
        IllegalArgumentException - if the value is not an instance of the acceptable types

      • toEpochNanos

        private static long toEpochNanos​(LocalDateTime timestamp)
        Get the number of nanoseconds past epoch of the given LocalDateTime.
        Parameters:
        timestamp - the Java timestamp value
        Returns:
        the epoch nanoseconds

      • toEpochNanos

        private static long toEpochNanos​(LocalDate date)
        Get the number of nanoseconds past epoch of the given LocalDate.
        Parameters:
        date - the Java date value
        Returns:
        the epoch nanoseconds
