Sqitch VS Apache Calcite

We use https://sqitch.org/ and we’re fairly happy with it. Sqitch manages the files to deploy which are applied fits to a local database. We use GitHub actions for deployment and database migrations are just one step of the pipeline. The step invokes sqitch deploy which runs all the pending migration files. Then, all the approval process is standard for the environment. We require approvals in pull requests... - Source: Hacker News / about 1 month ago

I'm experimenting with it right now using Squitch [1] to make maintenance easier. It still feels like a hack and I also still have my doubts about the viability of this for real-world use. It's fun though and I'm learning about all kinds of advanced Postgres features. [1] https://sqitch.org/. - Source: Hacker News / 5 months ago

How does it compare with other SQL-based migration tools like Sqitch? Source: about 1 year ago

Yup, same. Last time I set this up I used Sqitch¹ for migrations, which encourages you to write tests for each migration; caught a lot of bugs early that way, all in a local-first dev environment. Worked especially well for Postgres since plpgsql makes it easy to write tests more imperatively. ¹: https://sqitch.org/. - Source: Hacker News / over 1 year ago

> Make diff work on more than just SQLite. Another way of doing this that I've been wanting to do for a while is to implement the DIFF operator in Apache Calcite[0]. Using Calcite, DIFF could be implemented as rewrite rules to generate the appropriate SQL to be directly executed against the database or the DIFF operator can be implemented outside of the database (which the original paper shows is more efficient).... - Source: Hacker News / 10 months ago

Use a SQL Parser like sqlglot or Apache Calcite to compile user's query into an AST. Source: about 1 year ago

One parser I think deserves a mention is the one from Apache Calcite[0]. Calcite does more than parsing, there are a number of users who pick up Calcite just for the parser. While the default parser attempts to adhere strictly to the SQL standard, of interest is also the Babel parser, which aims to be as permissive as possible in accepting different dialects of SQL. Disclaimer: I am on the PMC of Apache Calcite,... - Source: Hacker News / over 1 year ago

Apache Calcite can do this, though it's not a beginner-friendly task: https://calcite.apache.org/. - Source: Hacker News / almost 2 years ago

You should look at Apache Calcite[0]. Like OctoSQL, you can join data from different data sources. It's also relatively easy to add your own data sources ("adapters" in Calcite lingo) and rules to efficiently query those sources. Calcite already has adapters that do things like read from HTML tables over HTTP, files on your file system, running processes, etc. This is in addition to connecting to a bunch of... - Source: Hacker News / almost 2 years ago
