# Betfair Data
Betfair Data is a very fast, Rust based, Betfair historical data parsing library for python. It supports both the official [Betfair's historic data](https://historicdata.betfair.com/#/home) and self recorded stream files.
## Installation
```
pip install betfair_data
```
Note: requires Python >= 3.7.
## Example
```python
import betfair_data as bfd
paths = [
"data/2021_12_DecRacingAUPro.tar",
"data/2021_10_OctRacingAUPro.tar",
"data/2021_11_NovRacingAUPro.tar",
]
market_count = 0
update_count = 0
for file in bfd.Files(paths):
market_count += 1
for market in file:
update_count += 1
print(f"Markets {market_count} Updates {update_count}", end='\r')
print(f"Markets {market_count} Updates {update_count}")
```
## Loading Files
You can read in files quickly in a worker thread using the provided ```Files``` utility. It supports reading in bz2, gzip or uncompressed (.json) stream files or .tar or .zip archives containing such files.
```python
paths = [
"data/2021_10_OctRacingAUPro.tar",
"data/2021_11_NovRacingAUPro.zip",
"data/self_recorded_market.gz",
"data/uncompressed_market.json",
]
files = bfd.Files(paths)
```
Or you can use the glob library to find and select all the paths automatically.
```python
import glob
paths = glob.glob("data/betfair_official/*.tar") + glob.glob("data/self_recorded/*.gz")
files = bfd.Files(paths)
```
You can also load the file through any other means and pass the raw bytes and name into the File object constructor.
```python
# generator to read in files
def load_files(paths: str):
for path in glob.glob(paths, recursive=True):
with open(path, "rb") as file:
yield bfd.File(path, file.read())
for file in load_files("markets/*.json"):
for market in file:
pass
```
## Benchmarks
Running over 3 months of Australian racing data on a 2021 M1 Macbook Pro.
| betfair_data (mutable) | betfair_data (immutable/bflw compat) | betfairlightweight lightweight=True | betfairlightweight lightweight=False|
| -----------------------|--------------------------------------|-------------------------------------|-------------------------------------|
| 5m 12sec | 6m 50sec | 1hour 1min 45sec | 3hours 46mins 39sec |
| ~70 markets/sec | ~53.5 markets/sec | ~6 markets/sec | ~1.62 markets/sec |
| ~534,200 updates/sec | ~406,500 updates/sec | ~45,500 updates/sec | ~12,250 updates/sec |
## Types
IDE's should automatically detect the types and provide checking and auto complete. See the [pyi stub file](betfair_data/betfair_data.pyi) for a comprehensive view of the types and method available.
## Betfairlightweight
We also support a format that is a drop in replacement for ```betfairlightweight``` objects. We have rigorously tested it against betfairlightweight to ensure a complete match of its structure, any differences should be submitted as issues with the corresponding differences and the data used to create them.
```py
from betfair_data import bflw
files = bflw.Files(paths)
```
```py
from betfair_data import bflw
file_bytes = ...
file = bflw.File("file_name", file_bytes)
```
## Logging
Logging can be enabled and warnings are emitted for IO and JSON errors.
```python
import logging
logging.basicConfig(level=logging.WARN, format='%(levelname)s %(name)s %(message)s')
```
Example logged errors
```log
