+/**
+ * <i>Experimental</i>

+ * <p>Wraps the {@link PubsubIO} with JSON messages into {@link BeamSqlTable}.
+ *
+ * <p>This enables {@link PubsubIO} registration in Beam SQL environment as a
table, including DDL
+ * support.
+ *
+ * <p>For example:
+ * <pre>
+ *
+ * CREATE TABLE topic (name VARCHAR, age INTEGER)
+ * TYPE 'pubsub'
+ * LOCATION projects/<GCP project id>/topics/<topic name>
+ * TBLPROPERTIES '{ \"timestampAttributeKey\" : <timestamp
attribute> }';
Review comment:
<!--new_thread; commit:464b72bb1ce835937c456f661d5d90e86ae76c94;

As a next generalization, it would be nice if the meta-format of JSON could
be specified in the TBLPROPERTIES. That would leave a natural hook for other
formats, or eventually some sort of UDF hook.
