Database Transaction Processing

Syndicate content 10 

Hi,
We recover a large amount of data from an external database (SQLServer, about 1 million rows in JDBC).
However, we have treatment time issue.
This process takes more than 30 minutes whereas on a "classic" SQL Server Management Studio type request takes less than a minute.

While searching on the internet, I came across this article: http://makejavafaster.blogspot.com/2015/06/jdbc-fetch-size-performance.html
It explains how in Java, we can tweak the FetchSize parameter of the JDBC driver to optimize this kind of process.

Is there a way to access this JDBC parameter through the EnsLib.SQL.OutboundAdapter adapter?

If not, how do you deal with this kind of situation of large volumetry

If I wanted to build a web-based dashboard that monitored various HIE transactions where would I start?

Examples of measures would be Provide & Registers by Facility, Patient Views by facility or even PHR related data.

I have a successful POC that uses nodejs, html and SQL but I think it makes more sense to use Intersystems technology all the way around, I just don't know where to begin.

CSP for the web piece I assume?  How would I access the data, for instance all P&R requests on the BUS?  Any other tips or starting points?  Maybe examples of a similar project?

 

We do not have a DeepSee license
