Hello, I would like to propose the following presentation for a meetup.
Thank you, Mihai Budiu ----------------- Building a streaming incremental view maintenance engine with Calcite Speaker: Mihai Budiu - VMware Research Duration: 20-40 minutes The DBSP open-source project (https://github.com/vmware/database-stream-processor) is a Rust runtime that unifies seamlessly streaming queries and incremental view maintenance (IVM). The SQL to DBSP compiler is an open-source (https://github.com/vmware/sql-to-dbsp-compiler) SQL compiler, based on Calcite, that targets the DBSP runtime. The compiler has passed more than 7 million SQL tests from SQLLogicTest (with 3 tests failing). We will present the core design of the IVM engine and the way we use Calcite to compile SQL to streaming computations. We discuss a few syntactic and sematic differences between SQL dialects that we have identified. Should Calcite support a notion of an "input SQL dialect", that would allow it to emulate behaviors that differ between other established SQL engines? > -----Original Message----- > From: Alessandro Solimando <alessandro.solima...@gmail.com> > Sent: Monday, February 6, 2023 12:00 AM > To: dev@calcite.apache.org > Subject: Re: [DISCUSS] Apache Calcite Meetup March 2023 > > !!
