dictomaton VS FusionCache

Say you want to compute all strings of length 5 that the automaton can generate. Conceptually the nicest way is to create an automaton that matches any five characters and then compute the intersection between that automaton and the regex automaton. Then you can generate all the strings in the intersection automaton. Of course, IRL, you wouldn't actually generate the intersection (you can easily do this on the fly), but you get the idea.

Automata are really a lost art in modern natural language processing. We used to do things like store a large vocabulary in an deterministic acyclic minimized automaton (nice and compact, so-called dictionary automaton). And then to find, say all words within Levenshtein distance 2 of hacker, create a Levenshtein automaton for hacker and then compute (on the fly) the intersection between the Levenshtein automaton and the dictionary automaton. The language of the automaton is then all words within the intersection automaton.

I wrote a Java package a decade ago that implements some of this stuff:

Also related: Levenshtein automata - automata for words that match every word within a given Levenshtein distance. The intersection of a Levenshtein automaton of a word and a DAWG gives you an automaton of all words within the given edit distance.

I haven't done any Java in years, but I made a Java package in 2013 that supports: DAWGs, Levenshtein automata and perfect hash automata:

Want an easy to use cache with advanced resiliency features? Look no further than FusionCache. It's built for performance, good refresh rates, better auto-setup, better logs, and more. Congrats to the team on shipping your first major and stable version 🎉 and receiving over 3.8 million downloads.

I wrote an internal nuget package for our team that does similar stuff to your work, although I called mine ICachedRequest. Unlike you I denied myself the enjoyment of exploring a custom caching solution and ended up injecting FusionCache into my mediatr behavior.

The most undervalued library from that list is FusionCache. The rest is either well-known (like FluentAssertions) or pretty specific to the guy's experience (like the WPF stuff).

The instances (using FusionCache for instance) sync over Redis pub/sub.

LazyCache is amazing. Btw I'm using FusionCache and it is good too

If you are in the .NET space I suggest you to take a look at FusionCache. It has cache stampede protection built in, plus some other nice features like a fail-safe mechanism and soft/hard timeouts https://github.com/jodydonetti/ZiggyCreatures.FusionCache
