How Data Virtualization can display the data in real time?

Latest response

Hello! I've always heard that data virtualization achieves an information response in real time and wants to know if there is a source that supports how it achieves it; If you have a link or document would appreciate it very much

Hello Cristopher

Thank you for contacting us. You can use materialization to cache and view the data. Here is the relevant chapter of the Red Hat JBoss Data Virtualization Development Guide Volume 5: Caching:

I hope this helps. If you are a Red Hat subscriber, you can contact our global support team for further advice.

Kind regards,

David Le Sage Documentation Team Leader, Red Hat

I have seen that when materializing views in other databases causes a mismatch of that view with the original source, then you are telling me that a materialized view in data virtualization allows me to view the information in real time?... Continuing with the topic of table materialization I see it very convenient since it would store the data in cache and in that way it extracts them. But, if in case I did not materialize that view the data virtualization would go to the source for every query that does or also works with cache without programming it?

Hello Cristopher,

Red Hat JBoss Data Virtualization takes data from multiple databases and datasources and generates a logical view of them. You see the results in real time. There should be no mismatch there. A materialized view caches the results for you. It would go to the source for information that has not been cached.

I hope this helps.

Can I ask how are you finding the documentation, particularly the Caching Guide (Dev Guide Volume 5)? Is it addressing most of your questions? In what ways can we improve it to further meet your needs?

Kind regards,

David Le Sage, Documentation Team Leader, Red Hat.
