withMaxNumRecords
Define the max number of records received by theSqsIO.Read
. When the max number of records is lower thanLong.MAX_VALUE
, theSqsIO.Read
will provide a boundedPCollection
. -
withMaxReadTime
Define the max read time (duration) while theSqsIO.Read
will receive messages. When this max read time is not null, theSqsIO.Read
will provide a boundedPCollection
. -
withQueueUrl
Define the queueUrl used by theSqsIO.Read
to receive messages from SQS. -
withClientConfiguration
Configuration of SQS client. -
expand
Description copied from class:PTransform
Override this method to specify how thisPTransform
should be expanded on the givenInputT
.NOTE: This method should not be called directly. Instead apply the
PTransform
should be applied to theInputT
using theapply
method.Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
