Method Detail

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
