RestClient
surfaces 429 HTTP status code as error for one
or more of the items in the Response
. Users should consider that retrying might
compound the underlying problem which caused the initial failure. Users should also be aware
that once retrying is exhausted the error is surfaced to the runner which may then
opt to retry the current bundle in entirety or abort if the max number of retries of the
runner is completed. Retrying uses an exponential backoff algorithm, with minimum backoff of
5 seconds and then surfacing the error once the maximum number of retries or maximum
configuration duration is exceeded.
Example use:
ElasticsearchIO.write()
.withRetryConfiguration(ElasticsearchIO.RetryConfiguration.create(10, Duration.standardMinutes(3))

PTransform
PTransform
should be expanded on the given
InputT
.
NOTE: This method should not be called directly. Instead apply the PTransform
should
be applied to the InputT
using the apply
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).
