Update 2

As of August 28th, 2025, Expert LSP has been released: https://github.com/elixir-lang/expert

Although still a work in progress, the plan is for the other three LS implementations to be archived. I may try to come up with a new way to track Expert's featureset, but I would probably contribute that back to Expert as documentation.

Update

As of August 15, 2024, it's been announced that the three projects bein compared here will soon merge! See the official Elixir blog post for more details: https://elixir-lang.org/blog/2024/08/15/welcome-elixir-language-server-team/

Big-O Time Complexities for Elixir data structures

Map [1]

Operation	Time Complexity
Access	`O(log n)`
Search	`O(log n)`
Insertion	`O(n)` for <= 32 elements, `O(log n)` for > 32 elements [2]
Deletion	`O(n)` for <= 32 elements, `O(log n)` for > 32 elements

Pretende usar `UUID` como PK em vez de `Int/BigInt` no seu banco de dados? Pense novamente...

TL;TD

Não use UUID como PK nas tabelas do seu banco de dados.

Um pouco mais de detalhes

Get boot2docker working with nfs instead of vboxsf.

Tested on:

- Boot2Docker-cli version: v1.6.0
