Bol has plenty of other ETL pipelines for BI. What I meant is the data cooked for search is not (much) of interest to BI, yet. Though we do have other means to feed BI for search-relevant content.
But I understand now what you actually mean. I wouldn't call it ETL, as ETL is more about prepping the data for BI and not cooking data for search.
yea, I remember they used to have redwood for scheduling PL/SQL queries but I think majority of ETL jobs for BI were in hadoop/spark/flink.
Having said all these, I think it is quite some neat and cool engineering work, I hope you guys are successful implementing the solution.
