Can you create custom jinja template to load all filters by using 1 query?

Can you create custom jinja template to load all filters by using 1 query? For example, every filter i use is calling the same dataset and i have more than 10 queries that loading at same time and 5 diagrammas so bcs of that i have very bad performance. I am looking for way to reduce the problem with performance. How can i do that? Can i load all filters by using 1 query or mb i can use jinja template? Or how can i fix my performance issues. Bcs my queries are kinda easy, but bcs of amount queries of same time my dashboard can load like 30 seconds

To address performance issues in Apache Superset when multiple filters are applied, you can consider the following approaches:

1. Consolidate Queries: While there isn't a direct method to consolidate all filter queries into a single query using Jinja templates, you can optimize your queries by creating a view in your database that pre-aggregates or pre-filters the data. This way, you can reduce the number of queries executed simultaneously.

2. Use Jinja Templates for Optimization: You can use Jinja templates to dynamically construct queries based on filter values. This can help in reducing redundancy and improving performance. For example, you can define a Jinja template that constructs a query with all necessary filters applied at once.

3. Enable Caching: Implement caching mechanisms to store query results temporarily. This can significantly reduce load times for dashboards with repeated queries.

4. Optimize Database Performance: Ensure that your database is optimized with appropriate indexes and that it can handle the load efficiently. This includes tuning your data warehouse for better performance.

5. Limit Group By Operations: Avoid using GROUP BY in your views if possible, as Superset will perform its own GROUP BY operations, which can lead to redundant processing and slow down performance ^[1][2].

By implementing these strategies, you can improve the performance of your Superset dashboards.
