Alternative solution to a materialized view

Hi,

I need to create a view with some joins but I cannot create a materialized view because I haven't any aggregations (no group by).

The view performances are important and I'd like to engage a minimum administrative effort.

So, does it exist an alternative solution to a materialized view?

Thanks

    Create suitable indexes on the base tables for the JOIN conditions; much better then a materilized (indexed) view.

    @pmscorca

    Thanks for reaching out to Microsoft Q&A.

    In the context of Azure Synapse Analytics, managing indexes does require some administrative effort, but it’s often considered minimal compared to the performance benefits it can provide.

    Here’s why:

    Index Creation: The initial setup of creating indexes requires understanding of the data and the queries that will be run against it. This involves some effort.

    Index Maintenance: Over time, as data changes, indexes can become fragmented and less effective. Therefore, they need to be periodically rebuilt or reorganized. Azure Synapse Analytics provides automatic index maintenance, but you may still want to manually tune and maintain your indexes depending on your specific workload.

    Storage Considerations: Indexes take up storage space. This is an important consideration especially if you are working with large volumes of data.

    Update Overhead: While indexes can speed up read operations, they can slow down write operations (INSERT, UPDATE, DELETE) because each write operation must also update the index.

    So, while there is some administrative effort involved in managing indexes, the potential performance gains often make it a worthwhile investment. Plus, with the tools and automation provided by Azure Synapse Analytics, much of the routine maintenance can be handled for you, minimizing the administrative burden.

    Remember, the key to effective indexing is understanding your data and how it’s queried. Regular monitoring and tuning can help ensure your indexes continue to improve performance over time.

    Hope this helps. Do let us know if you any further queries.
