Fetches and caches ETF data daily, from csv download or api, and saves the data to a parquet file
The code for the REST API is [github.com/NexVeridian/ark-invest-api-rust](https://github.com/NexVeridian/ark-invest-api-rust) and is hosted at [api.NexVeridian.com](https://api.NexVeridian.com)

# Install
Copy docker-compose.yml
Create data folder next to docker-compose.yml
```
├───data
│ └───parquet
├───docker-compose.yml
```
`docker compose up --pull always`
If building the parquet file from the first time use: `ARK_SOURCE=ApiFull` or `ARK_SOURCE=ArkFundsIoFull`
Afterwards use `ARK_SOURCE=ApiIncremental`
# Changing the data source
In docker-compose.yml, change the data source by changing the environment variable
```
environment:
- ARK_SOURCE=ApiIncremental
```
Env string ARK_SOURCE must be in the enum Source
```rust
pub enum Source {
// Reads Parquet file if exists
Read,
// From ARK Invest
Ark,
// From api.NexVeridian.com
#[default]
ApiIncremental,
// From api.NexVeridian.com, not usually nessisary, use ApiIncremental
ApiFull,
// From arkfunds.io/api, avoid using, use ApiIncremental instead
ArkFundsIoIncremental,
// From arkfunds.io/api, avoid using, use ApiFull instead
ArkFundsIoFull,
}
```
