Method Detail

withMaxNumRecords

public SqsIO.Read withMaxNumRecords(long maxNumRecords)

Define the max number of records received by the SqsIO.Read. When the max number of records is lower than Long.MAX_VALUE, the SqsIO.Read will provide a bounded PCollection.

withMaxReadTime

public SqsIO.Read withMaxReadTime(org.joda.time.Duration maxReadTime)

Define the max read time (duration) while the SqsIO.Read will receive messages. When this max read time is not null, the SqsIO.Read will provide a bounded PCollection.

withQueueUrl

public SqsIO.Read withQueueUrl(java.lang.String queueUrl)

Define the queueUrl used by the SqsIO.Read to receive messages from SQS.

withClientConfiguration

public SqsIO.Read withClientConfiguration(ClientConfiguration config)

Configuration of SQS client.
