GitHub user dosubot[bot] added a comment to the discussion: Can you create custom jinja template to load all filters by using 1 query?
<!-- Answer --> 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 <sup>[[1]](https://github.com/apache/superset/discussions/32343)</sup><sup>[[2]](https://github.com/apache/superset/blob/master/docs/docs/faq.mdx)</sup>. By implementing these strategies, you can improve the performance of your Superset dashboards. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
