"Just Send Us the File": The Two-Sided Data Sharing Problem Between ISVs and Their Customers, and the One Engine That Solves Both
J
18:10Jeanne GlassHOST
Can you talk a little bit, Vince, about what Zafin built and what's running today and then share any other customer examples you want to weave in there as well?
V
18:20Vince ReGUEST
Yeah, well, and I think Zafin actually is a great example of everything that I've talked about.
V
18:26Vince ReGUEST
You know, they had exactly that case where customers would send huge amounts of data.
V
18:34Vince ReGUEST
And, you know, what Zafin had done was gone down the path of, you know, custom ingestion per customer because of the differences from customer A to customer B and, you know, so on and so on.
V
18:50Vince ReGUEST
You know, I think that the ultimate issue they got into with that is just the processing time got to be, you know, relatively enormous there.
V
19:04Vince ReGUEST
You know, the customer could change something and all of a sudden, you know, Zavin might not even know it.

How does Propels help the mainframe team who's already got these tens of extract programs and a line out the door?
PropelZ Multiplexer: Moving a Million Mainframe Data Sets from z/OS to the Cloud in Parallel
V
7:20Vince ReGUEST
mean, just to cover propels from a high level for anyone who might not be familiar with the core technology.
V
7:38Vince ReGUEST
At the core is a series of things like data filtering and transformations and so on and so on.
V
7:49Vince ReGUEST
We know how to take complicated binary objects, let's say a record from a VSAM file, and we know how to transform that into a lot of different things.
V
8:01Vince ReGUEST
It could be a JSON object, an XML object, but certainly the most common thing would be a format that can be inserted directly into some type of database.
V
8:15Vince ReGUEST
Database could be on-prem, it could be in the cloud, doesn't really matter too much to us.

Why ETL and Change Data Capture Break at Mainframe Scale — and What Replaces Them
V
2:38Vince ReGUEST
Yeah, well, and just to build on your example, I think the customer you're referencing had actually been through all of these three.
V
2:53Vince ReGUEST
I mean, something we see a lot of folks do is they'll go down the path of ETL, extract, transform, and load.
V
3:04Vince ReGUEST
And the idea there is that, you know, you have to know the structure of your data and you do something, you know, you use, you know, utility from one of our competitors, maybe you write custom COBOL programs, you know, whatever you want to do, you create, you know, data dependent scripts that can transform your data into something useful.

8:11Marc SokolHOST
Why don't you talk a little bit about what the actual setup was and how we accomplish this?
