Tried the “multi” inputSpec for merging N datasources into one. The ingestion worked without any errors but the result is not what I’ve expected.
I have at input 2 datasources:
- ds1 with metric clicks - value 100 after rollup
- ds2 with metric click - value 100 after rollup
After running the “multi” ingestion specifying the 2 datasources above at input and ds3 datasource at output, I have data only from the first datasource: click metric - 100.
I expected the ingestion to aggregate the data from both input datasources and have click - 200.
Did I misunderstand the usage/reason of “multi” inputSpec feature or I did something wrong?
That worked with the CombiningFirehose with 2 ingestSegment delegates.
