VSCatalog : Enable Parallel Streams to fetch data from VSE

Products

• Service Virtualization

Issue/Introduction

Fetching of data from VSE will happen sequentially across all connections and across all registries. This may slow down processing.  If you have smaller size VSIs, then it is better to enable parallel processing by setting this property svcatalog.devtest.enableParallelProcessingOfVSEData to true

Environment

VSCatalog 10.8.x or newer

Resolution

Add the below property in VSCatalog  'application.yaml' file 

svcatalog.devtest.enableParallelProcessingOfVSEData: true

 

Note ***

 If you have many VSI files that are above 200 MB in size, then set this property svcatalog.devtest.enableParallelProcessingOfVSEData to false. This will disable Parallel Streams. Huge VSI files need very large heap of above 8GB if parallel streams are used. In case if there is not enough heap, them OOM errors may occur.
