# ecto_struct_cachex [](https://hex.pm/packages/ecto_struct_cachex) [](https://hexdocs.pm/ecto_struct_cachex/)
in-memory cache for ecto struct.
## Installation
Add ecto_struct_cachex to your list of dependencies in `mix.exs`:
```elixir
def deps do
[{:ecto_struct_cachex, "~> 0.2.0"}]
end
```
run `mix deps.get`.
## Sample
This Sample Project is the basis for ecto_struct_cachex, help you use well.
Download via [Gitee](https://gitee.com/lizhaochao/ecto_struct_cachex_sample) or [Github](https://github.com/lizhaochao/ecto_struct_cachex_sample).
## Problems Solving
- **Support get struct by keyword from cache.**
```elixir
defmodule API do
@decorate cache_object(User)
def get_user(conds) do
...
{:ok, user}
end
end
# pass keyword to get object.
API.get_user([name: "name", addr: "addr"])
```
- **Delete dirty structs when its deep nested struct updated/deleted.**
```elixir
%User{
id: 1,
user_name: "u_name",
role: %Role{id: 2, role_name: "r_name"}
}
```
For above sample struct, role struct deleted/upadted, user struct will be deleted too.
## Benchmark
```bash
mix bench
## LRUBench
benchmark name iterations average time
only put 100000000 0.09 µs/op
get - empty cond 10000000 0.15 µs/op
put - should remove 10000000 0.23 µs/op
get - by id - obj at top 10000000 0.27 µs/op
get - by conds - obj at top 10000000 0.58 µs/op
get - by conds - obj at mid 1000000 1.71 µs/op
get - by conds - obj at bottom 1000000 2.21 µs/op
```
