Introduction
Open Source BI Helical Insight version 6.2 introduces a major architectural enhancement with support for Streaming Response along with the implementation of an optimized Stream Cache Strategy.
If you plan to view multi pager data, then this configuration can give immense performance boost. Since page wise data we mainly see in canned report, in interactive report (hreport) also when we see the report in table format and you can easily see a performance improvement by more than 85-90%.
Further this version also helps with performance improvement of interactive charts/ dashboards also by nearly 50%.
Steps to Enable Streaming Response Configuration:
In our future versions, we will have this setting by default enable. But if you are using 6.2 or upgrading from older version to this version you will have to manually enable this setting.
1. Update cache.xml
Open the cache.xml file which is present at the location:
Change value of cacheStrategy from default to stream i.e. from:
<cacheStrategy>default</cacheStrategy>
To:
<cacheStrategy>stream</cacheStrategy>
Also change:
<enableParallelReportGeneration>false</enableParallelReportGeneration>
To:
<enableParallelReportGeneration>true</enableParallelReportGeneration>
2. Update setting.xml
Open the setting.xml file present at the below location:
Change:
<streamResponse>false</streamResponse>
To:
<streamResponse>true</streamResponse>
3. Save all configuration changes and clear the application cache from the Helical Insight home page.
Note:
Cache files will be generated in the below server path:
