Adapter for RDBMS to support multiple rows with same "Timestamp" colum as IndexColumn

As of version 1.x, with the IndexColumn being specified in the dataselection, the Adapter will require that each row in the source Database to have its own unique timestamp. If there are multiple rows with the same timestamp, first value with the timestamp will be processed but subsequent values would be skipped.

Removing IndexColumn, and let the Adapter timestamp the data, Adapter will be able to process all the rows retrieved. However, this is not an ideal workaround as the data's timestamp will not be as per the source Database.

Interface is able to process these rows and send to PI Data Archive depending on the configuration set (for example, append/replace/do nothing if value is the same).

This enhancement request is such that the Adapter is able to process multiple rows with same the timestamp and send the data.

    Would it be possible to add additional context to this enhancement request?

    My current understanding is that you would like multiple rows to be associated with a singular timestamp. Are these multiple rows associated with different data streams, or the same data stream?


    Would you be able to provide a brief example of the data you're trying to ingress?
