  • PostgreSQL Logical Replication Explained
    4 projects | news.ycombinator.com | 18 Mar 2023
    For C there should be good options.

    For Rust it doesn't appear that well-supported.

    A very simple approach is to poll for changes using `pg_logical_slot_get_changes()` - that should work with any driver. That's what I used for my initial experimentation, before switching over to the streaming replication protocol for better performance.

    The streaming replication protocol is not that complicated, but currently you'll have to handle some of the low-level protocol yourself, or work with some very experimental implementations. There's a project to help get you started at [1], and some more discussion at [2].

    For the logical decoder, wal2json is quite nice to experiment with, but I've found pgoutput is not that complicated and gives you something closer to the raw data.

  • Reviews of the Diesel ORM, are there better alternatives?
    11 projects | /r/rust | 15 May 2022
    I can understand that this can be frustrating and I know that the situation there is not ideal for diesel. There are certainly things to improve there by either providing a bundling support which builds the native library as part of the normal build process or by implementing a pure rust connection implementation. Both is possible with diesel, but requires some work. At least the pure rust connection implementation is something that can be provided by a third party crate now with upcoming diesel 2.0 release. If you are interested in that checkout this and this issue. As for the bundling support: This requires changes in the mysqlclient-sys and pq-sys crates. Again help there is welcome. In the end it makes me sad that some people have repeating decided that a solution to this problem is to write just another crate instead of helping to fix these issues. This just results in everyone have more work to do, as there are now two non-perfect solutions instead of having one slightly improved solution.
  • GitHub - tzConnectBerlin/rust-pg_bigdecimal: A Rust native datatype for Postgres' Numeric type, to be used with Rust's "Postgres" library.

    We created this little library to have a fully native type for Postgres Numerics with the rust-postgres (https://github.com/sfackler/rust-postgres) library.
  • pigeon-rs: Open source email automation written in Rust
    5 projects | /r/rust | 20 Nov 2021
    The problem with a crate like postgres is that you have to define the types of the query at compile-time. And if you use the simple query protocol in postgres, you just get a bunch of strings, i.e. no proper typing at all. However, for maximal flexibility arbitrary queries should work in pigeon, without knowing the database schema.
  • Announcing Usual -- a small nORM wrapper to make dealing with SQL easier (like tokio-postgres)
    2 projects | /r/rust | 25 Aug 2021
    Some nifty things about usual: - It's a generic wrapper over any SQL "row" object. The first implementation that's provided is for tokio-postgres, but traits are available to implement over whatever you'd like. - It provides static typing for partial queries. That is, it supports fetching a subset of fields from a row and makes a unique type for the return value. This gives you some neat-o type safety like this:
