Class WriteTimeCodec<T>

java.lang.Object

com.datastax.oss.dsbulk.codecs.api.ConvertingCodec<T,Long>

com.datastax.oss.dsbulk.codecs.api.writetime.WriteTimeCodec<T>

Type Parameters:

T - The external type.

All Implemented Interfaces:

TypeCodec<T>

public class WriteTimeCodec<T>
extends ConvertingCodec<T,Long>

A special wrapper codec that maps write times to and from an external format.

Write times are inserted using an USING TIMESTAMP clause and can be retrieved using the WRITETIME function, as in writetime(mycol). Write times are always expressed internally as bigints representing microseconds since the Unix Epoch.
