Would be interesting to see what you could achieve with Julia for this challenge

sounds good! 👍 i invited you to the org if you want to spearhead that or link to an existing persons repo. 🚀

I can try to set up some repos and ask some uni friends if they wanna try!

I have the original code right here.

    Extremely naive implementation of the 1BRC task.

"""
function process_data(filepath::String)
    stats = Dict{String,Dict{String,Float32}}()

    open(filepath) do f
        for row in eachline(f)
            city, temp_str = split(row, ';')
            temp = parse(Float32, temp_str)

            if haskey(stats, city)
                city_stats = stats[city]
                # ifelse is faster than min/max
                city_stats["min"] = ifelse(temp < city_stats["min"], temp, city_stats["min"])
                city_stats["max"] = ifelse(temp > city_stats["max"], temp, city_stats["max"])
                city_stats["sum"] += temp
                city_stats["count"] += 1
            else
                stats[city] = Dict("min" => temp, "max" => temp, "sum" => temp, "count" => 1)
            end
        end
    end

    return stats
end

function print_stats(stats)
    for (city, city_stats) in stats
        min_temp = city_stats["min"]
        max_temp = city_stats["max"]
        avg_temp = city_stats["sum"] / city_stats["count"]
        println("$city: min=$min_temp, max=$max_temp, avg=$avg_temp")
    end
end

if abspath(PROGRAM_FILE) == @__FILE__
    filepath = length(ARGS) < 2 ? ARGS[2] : "data.txt"
    process_data(filepath) |> print_stats
end

I have yet to complete the more optimized one, but where do I go from here. Might have missed it in the docs!

you can either add the repo as a link and host the competition/submissiosn under your username or add it to @1brc like the nodejs and bun stuff was added to this org. up to you 🤷‍♂️ do whatever you want lol

Indeed! I too have been playing with a Julia implementation last couple of weeks. I came here looking to open an issue, and found that you already beat me to it! 😄

I think we can share some notes in this discussion. I will also go through the Julia Discourse to gather more feedback.
