arrow-datafusion VS alacritty

Python's Substrait seems like the biggest/most-used competitor-ish out there. I'd love some compare & contrast; my sense is that Substrait has a smaller ambition, and more wants to be a language for talking about execution rather than a full on execution engine. https://github.com/substrait-io/substrait

We can also see from the DataFusion discussion that they too see themselves as a bit of a Velox competitor. https://github.com/apache/arrow-datafusion/discussions/6441

Agree, substrait is a really cool project! Related: if you like substrait you might want to check out datafusion too. The project is a query execution engine built on top of Apache Arrow (with SQL parser, query planner & optimizer, execution engine, extensible user defined functions, among others) and it implements a substrait provider and consumer: https://github.com/apache/arrow-datafusion/tree/main/datafus...

The draft contains some preliminary benchmark results, comparing it to DuckDB.

https://github.com/apache/arrow-datafusion/issues/6782

Apache Arrow is a pretty common memory structure these days. Datafusion is an open query engine built in Rust started by Andy Grove.

DuckDB is a great piece of software if you are

If you are looking for a query engine implemented in a safe language (Rust) I definitely suggest checking out DataFusion. It is comparable to DuckDB in performance, has all the standard built in SQL functionality, and is extensible in pretty much all areas (query language, data formats, catalogs, user defined functions, etc)

Disclaimer I am a maintainer of DataFusion

Problem comes when you want to do this inside an async context since we couldn't block an async task. https://users.rust-lang.org/t/sync-function-invoking-async/43364/6 You might need to do it in another runtime/thread. It is not recommended to do this, but sometimes it is unavoidable while implementing a third-party trait. https://github.com/apache/arrow-datafusion/issues/3777 However, I believe this isn't a problem particular to tokio, or any specific runtime.

It's opinionated, which comes with upsides and downsides. I won't blame the maintainer to keep things focused, feature creep (even for worthy features) can kill a FOSS project.

Another example is sixel support, there's a fork where it all works but is not sufficiently "proven" (code quality just as well as sixel being the best fit for the problem)

It may be annoying but I get the reasoning, and there are other terminals.

alacritty (Linux, Macos & Windows)

> Ligatures: ok, nice, possible in terms too (hopefully Alacritty one day)

I wouldn't hold my breath. Seems like its getting the iPad calculator treatment[0]. Which is to say rather than ship something working that can be improved, they're leaving a UX void.

IME, this is like the golden age of terminal apps in general and macOS-compatible ones in particular. There are several really good terminals for macOS:

[iTerm2 app](https://iterm2.com/)

[Kitty terminal](https://sw.kovidgoyal.net/kitty/)

[WezTerm terminal](https://wezfurlong.org/wezterm/index.html)

[Alacritty](https://github.com/alacritty/alacritty)

My daily driver is WezTerm…

- Runs on Linux, macOS, Windows 10 and FreeBSD

- [Multiplex terminal panes, tabs and windows on local and remote hosts, with native mouse and scrollback](https://wezfurlong.org/wezterm/multiplexing.html)

- [Ligatures](https://github.com/tonsky/FiraCode#fira-code-monospaced-font...), Color Emoji and font fallback, with true color and [dynamic color schemes](https://wezfurlong.org/wezterm/config/appearance.html#colors).

- [Hyperlinks](https://wezfurlong.org/wezterm/hyperlinks.html)

- [Searchable Scrollback](https://wezfurlong.org/wezterm/scrollback.html) (use mouse wheel and `Shift-PageUp` and `Shift PageDown` to navigate, Ctrl-Shift-F to activate search mode)

- xterm style selection of text with mouse; paste selection via `Shift-Insert` (bracketed paste is supported!)

- SGR style mouse reporting (works in vim and tmux)

- Render underline, double-underline, italic, bold, strikethrough (most other terminal emulators do not support as many render attributes)

- Configuration via a [configuration file](https://wezfurlong.org/wezterm/config/files.html) with hot reloading

- Multiple Windows (Hotkey: `Super-N`)

- Splits/Panes (Split horizontally/vertically: `Ctrl-Shift-Alt-%` and `Ctrl-Shift-Alt-"`, move between panes: `Ctrl-Shift-ArrowKey`)

- Tabs (Hotkey: `Super-T`, next/prev: `Super-Shift-[` and `Super-Shift-]`, go-to: `Super-[1-9]`)

- [SSH client with native tabs](https://wezfurlong.org/wezterm/ssh.html)

- [Connect to serial ports for embedded/Arduino work](https://wezfurlong.org/wezterm/serial.html)

- Connect to a local multiplexer server over unix domain sockets

- Connect to a remote multiplexer using SSH or TLS over TCP/IP

- iTerm2 compatible image protocol support, and built-in [imgcat command](https://wezfurlong.org/wezterm/imgcat.html)

- Kitty graphics support

- Sixel graphics support (experimental: starting in `20200620-160318-e00b076c`)

# We use Alacritty's default Linux config directory as our storage location here. mkdir -p ~/.config/alacritty/themes git clone https://github.com/alacritty/alacritty-theme ~/.config/alacritty/themes

if by 'in the terminal' you mean 'in a program emulating an ascii terminal' then no, because ascii terminals don't support anything that looks better than ascii art. they don't support sixel either. there are a variety of proposals for how to add graphics to ascii terminal emulators in a backwards-compatible way, such as mgr and notty https://github.com/alacritty/alacritty/issues/51

but the 'terminal' that a terminal emulator is emulating is a device which provides a user access to a remote computer. normally nowadays this is a laptop or cellphone. in that case, yes, you can use x-windows, xpra, vnc, or a web browser

A decent terminal application (i.e: iterm2, alacritty, etc.)

I have been having random input lags with Alacritty. Initially I thought it was my custom neovim config. After some investigation, I have found an Alacritty github issue where users are reporting the same issue: https://github.com/alacritty/alacritty/issues/6844

Thank you for your suggestions. I have now narrow it down to my terminal emulator. Alacritty. More precisely this issue: https://github.com/alacritty/alacritty/issues/6844
