cldellow / hash-matcher

Implementation of http://pzemtsov.github.io/2016/10/16/custom-hash-function.html in Scala

I like all things data. I've worked with data my whole career, from things that would fit in a Tweet all the way up to multi-petabyte data warehouses running in the cloud.

Currently, I'm a founder at SyncWith. We want anyone to be able to get their data into Google Sheets and Looker Studio.

As a hobby, I'm dabbling with making small datasets much more accessible via SQLite and Datasette plugins.

You can find me on the web at cldellow.com or as @cldellow on Hachyderm.

hash-matcher's Issues

Emit matcher code

Right now the only way to use this is to generate the function on demand. That involves a potentially costly search.

For my use case, this is OK since I'm generating the matcher and then running it in a long-running process. It might be nice to include a mode where you tell it the factor, it validates the factor is sane, and life continues.

Or, perhaps better, it can emit the relevant code. This might generate better bytecode, too, since things will be constants instead of variables.

Extend to longs

This idea can be extended to longs very easily. I haven't done it yet as my needs don't permit 8-character strings as inputs.
