2 Steps to download BVZ file: 

1. Open the dashboard in designer.
   
2. Top Right corner click Save to local disk.
   

Script for Background Highlight Style.
·        This is to be written on component Script.
·        This script changes the color on click of the respective component.

There are a number of ways to enhance the performance of BDB  pipelines:
 

• Optimize data storage and access: Ensuring that data is stored and accessed efficiently can help to improve the performance of BDB pipelines. This may involve using optimized data storage formats, such as columnar formats, and minimizing the amount of data that needs to be processed or accessed at any given time.
  
• Use parallel processing: BDB pipelines can often benefit from the use of parallel processing, which involves dividing the work of the pipeline into smaller chunks and processing them in parallel. This can help to improve the performance of the pipeline by taking advantage of the processing power of multiple machines or cores.
  
• Optimize data transformations: Data transformations can be resource-intensive, and optimizing the way they are performed can help to improve the performance of BDB pipelines. This may involve minimizing the amount of data that needs to be transformed, using optimized algorithms and libraries, or parallelizing the transformation process.
  
• Monitor and optimize resource usage: Monitoring resource usage and identifying bottlenecks can help to identify areas where the performance of BDB pipelines can be improved. This may involve optimizing the use of resources such as memory, CPU, or network bandwidth.
