    • type

      public final ShardIteratorType type()

      You can set the starting position to one of the following values:

      AT_SEQUENCE_NUMBER: Start streaming from the position denoted by the sequence number specified in the SequenceNumber field.

      AFTER_SEQUENCE_NUMBER: Start streaming right after the position denoted by the sequence number specified in the SequenceNumber field.

      AT_TIMESTAMP: Start streaming from the position denoted by the time stamp specified in the Timestamp field.

      TRIM_HORIZON: Start streaming at the last untrimmed record in the shard, which is the oldest data record in the shard.

      LATEST: Start streaming just after the most recent record in the shard, so that you always read the most recent data in the shard.

      If the service returns an enum value that is not available in the current SDK version, type will return ShardIteratorType.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from typeAsString().

      Returns:

      See Also:

    • sequenceNumber

      public final String sequenceNumber()

      The sequence number of the data record in the shard from which to start streaming. To specify a sequence number, set StartingPosition to AT_SEQUENCE_NUMBER or AFTER_SEQUENCE_NUMBER.

      Returns:
      The sequence number of the data record in the shard from which to start streaming. To specify a sequence number, set StartingPosition to AT_SEQUENCE_NUMBER or AFTER_SEQUENCE_NUMBER.

    • timestamp

      public final Instant timestamp()

      The time stamp of the data record from which to start reading. To specify a time stamp, set StartingPosition to Type AT_TIMESTAMP. A time stamp is the Unix epoch date with precision in milliseconds. For example, 2016-04-04T19:58:46.480-00:00 or 1459799926.480 . If a record with this exact time stamp does not exist, records will be streamed from the next (later) record. If the time stamp is older than the current trim horizon, records will be streamed from the oldest untrimmed data record (TRIM_HORIZON).

      Returns:
      The time stamp of the data record from which to start reading. To specify a time stamp, set StartingPosition to Type AT_TIMESTAMP. A time stamp is the Unix epoch date with precision in milliseconds. For example, 2016-04-04T19:58:46.480-00:00 or 1459799926.480.
