  • What I Talk About When I Talk About Query Optimizer (Part 1): IR Design
    7 projects | news.ycombinator.com | 29 Jan 2024
    We implemented a query optimizer with a flexible intermediate representation in pure Go:

    https://github.com/dolthub/go-mysql-server

    Getting the IR correct so that it's both easy to use and flexible enough to be useful is a really interesting design challenge. Our primary abstraction in the query plan is called a Node, and is way more general than the IR type described in the article from OP. This has probably hurt us: we only recently separated the responsibility to fetch rows into its own part of the runtime, out of the IR -- originally row fetching was coupled to the Node type directly.

    This is also the query engine that Dolt uses:

    https://github.com/dolthub/dolt

    But it has a plug-in architecture, so you can use the engine on any data source that implements a handful of Go interface.

    At the moment, it does not exist for DoltgreSQL as it is in pre-alpha. Dolt (https://github.com/dolthub/dolt), however, may be a better fit for your use case.

    > Do you have a clear position on which PostgreSQL features not to support? I suppose there are more than just some things that won't make the cut because of the architectural decisions.

    While I unnderstand the decision, I'm not sure it's the best way to go about it. If you only emulate a subset of PostgreSQL's syntax and features, few people will be compelled to switch because they might be afraid.

    Eventually, we'd like to support the entirety of PostgreSQL's feature set, even including features like extensions. Dolt (https://github.com/dolthub/dolt), our first product, is the same to MySQL and DoltgreSQL is to Postgres, and we're taking a no-compromises approach to what we support. That, of course, means that there are a lot of features that need to be implemented, but Dolt is already almost there. For the majority of customers, Dolt has implemented everything they need from MySQL.

    I'd definitely recommended checking out how Dolt compares with MySQL to see how we're approaching compatibility. All behavior, implicit and explicit, is something that we aim to model, and any deviations are considered bugs that we need to fix. There are exceptions, but those are only used when we feel it's for good reason (an example being how MySQL handles collation cascading in some circumstances).

    > Have you guys already encountered some things in the PostgreSQL engine that just behave a bit differently from Dolt's engine? If so, what was your approach to mitigate it?

    With DoltgreSQL, it's at an extremely early stage. We're still working on getting the basic functionality working before we rigorously start testing to make sure that we match PostgreSQL's behavior. However, we can point to our approach with Dolt and MySQL for how we plan to handle DoltgreSQL and PostgreSQL. For every feature we implement, we compare the functionality with what is written in MySQL's documentation as a baseline. From there, we move on to comparing the output across a range of input statements. Sometimes the documentation differs from MySQL's own results, and we then try to find out why that's the case (Configuration? Out of date documentation? Bug? etc.).

    We also use external benchmarks to measure our correctness versus MySQL. In one such benchmark, containing around 6 million tests, Dolt recently reached 99.99% compared to MySQL (https://www.dolthub.com/blog/2023-10-11-four-9s-correctness/).

    I hope this answered your questions! Let me know if you have any more :)

    Just want to point out that we're announcing development on the project. It's absolutely not ready for mainstream use yet! We have Dolt (https://github.com/dolthub/dolt) which is production-ready and widely in use, but it uses MySQL's syntax and wire protocol. We are building the Dolt equivalent for PostgreSQL, which is DoltgreSQL, but it's only pre-alpha.

    The engine is free and open-source. You can buy support, but these are free products.

    In fact, we've got a blog post about Dolt and Wordpress.

    We don't really compete with Flyway and Bytebase. Schema migrations are but one aspect of a versioned database. We version everything, from the schema to the data. You can read more here:

    https://www.dolthub.com/blog/2022-08-04-database-versioning/

    A lot of products have come out that attempt to tackle schema versioning, but none have tackled data versioning before Dolt (https://github.com/dolthub/dolt). In addition, our database isn't forked, it's a full, bespoke solution that can operate as a drop-in replacement for MySQL (Dolt) or PostgreSQL (DoltgreSQL). It's honestly quite exciting technology, so definitely feel free to ask any more questions if you're curious to learn more!

    Here is a link to a few use cases as well:

  • Pg_branch: Pre-alpha Postgres extension brings Neon-like branching
    6 projects | news.ycombinator.com | 1 Oct 2023
    Interesting that branching is now better supported and almost free. I wonder if merging can be simplified or whether it already is as simple and as fast as it can be?

    I guess I am inspired by Dolt’s ability to branch and merge: https://github.com/dolthub/dolt

    #. SQLite WAL mode

    From https://www.sqlite.org/isolation.html https://news.ycombinator.com/item?id=32247085 :

    > [sqlite] WAL mode permits simultaneous readers and writers. It can do this because changes do not overwrite the original database file, but rather go into the separate write-ahead log file. That means that readers can continue to read the old, original, unaltered content from the original database file at the same time that the writer is appending to the write-ahead log

    > Dolt can be set up as a replica of your existing MySQL or MariaDB database using standard MySQL binlog replication. Every write becomes a Dolt commit. This is a great way to get the version control benefits of Dolt and keep an existing MySQL or MariaDB database.

    > ibis strives to provide a consistent interface for interacting with a multitude of different analytical execution engines, most of which (but not all) speak some dialect of SQL.

    > Today, Ibis accomplishes this with a lot of help from `sqlalchemy` and `sqlglot` to handle differences in dialect, or we interact directly with available Python bindings (for instance with the pandas, datafusion, and polars backends).

    > [...] `Substrait` is a new cross-language serialization format for communicating (among other things) query plans. It's still in its early days, but there is already nascent support for Substrait in Apache Arrow, DuckDB, and Velox.

    > postlite is a network proxy to allow access to remote SQLite databases over the Postgres wire protocol. This allows GUI tools to be used on remote SQLite databases which can make administration easier.

    > The proxy works by translating Postgres frontend wire messages into SQLite transactions and converting results back into Postgres response wire messages. Many Postgres clients also inspect the pg_catalog to determine system information so Postlite mirrors this catalog by using an attached in-memory database with virtual tables. The proxy also performs minor rewriting on these system queries to convert them to usable SQLite syntax.

    > Note: This software is in alpha. Please report bugs. Postlite doesn't alter your database unless you issue INSERT, UPDATE, DELETE commands so it's probably safe. If anything, the Postlite process may die but it shouldn't affect your database.

    If you are just looking for data versioning there is Dolt:

    https://github.com/dolthub/dolt

    And that has a user-friendly UI in DoltHub:

    You wouldn't store the images themselves in Dolt, those would likely be links to S3 but al the labels and surrounding metadata could be stored in Dolt?
