FAQs
Why is delivery via S3 important?
- With data in S3, our customers can bulk download historical data in an analytics friendly format. This allows them to dig deep into the data and perform their own proprietary research and test trading strategies without being limited by our REST API throughput.
How does a customer get access to these datasets?
- Customers will need to have their own AWS credentials in which we will provision for S3 access. If you are interested in downloading data via S3, please contact your Account Executive.
Why Parquet format instead of a GZIP compressed JSON file?
- Parquet is a columnar storage format for structured data that is optimized for querying and analysis. In Parquet format, data is stored in columns rather than rows, allowing for more efficient compression and encoding of data. This can result in significant performance improvements for analytical workloads that involve large datasets and complex queries. Parquet is widely used in big data environments for data warehousing, analytics, and machine learning applications and can be easily integrated into existing data pipelines.
How do I download a parquet sample file and open it to see which fields are returned?
- If you only want to see the fields, simply download the sample parquet file, load it as a pandas dataframe in Python and use dataframe.dtypes, that'll give you a quick output of the field types. Here is the code available for you to try out:
#Import the pandas library
import pandas as pd
# Replace 'your_parquet_file.parquet' with the path to your Parquet file
parquet_file = 'your_parquet_file.parquet'
# Load the Parquet file as a pandas DataFrame
df = pd.read_parquet(parquet_file)
# Display the data types of the DataFrame
print(df.dtypes)
- Now if you wanted to actually read the parquet data, once you've downloaded the sample parquet file, you can run the following Python code:
#Import the pandas library
import pandas as pd
# Replace 'your_parquet_file.parquet' with the path to your Parquet file
parquet_file = 'your_parquet_file.parquet'
pd.read_parquet(parquet_file, engine='pyarrow')
