+/**
+ * An unbounded sink for Splunk's Http Event Collector (HEC).
+ *
+ * <p>For more information, see the online documentation at <a
+ *
href="https://dev.splunk.com/enterprise/docs/dataapps/httpeventcollector/";>Splunk
HEC</a>.
+ *
+ * <h3>Writing to Splunk's HEC</h3>
+ *
+ * <p>The {@link SplunkIO} class provides a {@link PTransform} that allows
writing {@link
+ * SplunkEvent} messages into a Splunk HEC end point.
+ *
+ * <p>It takes as an input a {@link PCollection
PCollection<SplunkEvent>}, where each {@link
+ * SplunkEvent} represents an event to be published to HEC.
+ *
+ * <p>To configure a {@link SplunkIO}, you must provide at a minimum:
+ *
+ * <ul>
+ * <li>url - HEC endpoint URL.
+ * <li>token - HEC endpoint token.
+ * </ul>
+ *
+ * <p>The {@link SplunkIO} transform can be customized further by optionally
specifying:
+ *
+ * <ul>
+ * <li>parallelism - Number of parallel requests to the HEC.
+ * <li>batchCount - Number of events in a single batch.
+ * <li>disableCertificateValidation - Whether to disable ssl validation
(useful for self-signed
+ * certificates)
+ * </ul>
+ *
+ * <p>This transform will return any non-transient write failures via a {@link
PCollection
+ * PCollection<SplunkWriteError>}, where each {@link SplunkWriteError}
captures the error that
+ * occurred while attempting to write to HEC. These can be published to a
dead-letter sink or
+ * reprocessed.
+ *
+ * <p>For example:
+ *
+ * <pre>{@code
+ * PCollection<SplunkEvent> events = ...;
+ *
+ * PCollection<SplunkWriteError> errors =
+ * events.apply("WriteToSplunk",
+ * SplunkIO.writeBuilder()
Review comment:
Thanks for that input! Switched to a fluent factory pattern for the
SplunkIO transform.
