> Tempura: extending Calcite into an incremental query optimizer
> --------------------------------------------------------------
>
> Key: CALCITE-4568
> URL: https://issues.apache.org/jira/browse/CALCITE-4568
> Project: Calcite
> Issue Type: New Feature
> Reporter: Botong Huang
> Priority: Major
>
> As discussed in the email thread, this is an attempt to extend the Calcite
> optimizer into a general incremental query optimizer, based on our research
> paper published in VLDB 2021:
> Tempura: a general cost-based optimizer framework for incremental data
> processing
> To our best knowledge, this is the first general cost-based incremental
> optimizer that can find the best plan across multiple families of incremental
> computing methods, including IVM, Streaming, DBToaster, etc. Experiments (in
> the paper) shows that the generated best plan is consistently much better
> than the plans from each individual method alone.
> In general, incremental query planning is central to database view
> maintenance and stream processing systems, and are being adopted in active
> databases, resumable query execution, approximate query processing, etc. We
> are hoping that this feature can help widening the spectrum of Calcite,
> solicit more use cases and adoption of Calcite.
