Automating CSV to Parquet Conversion with Hugging Face Buckets, Webhooks, and Jobs
ORIGINAL / Automate CSV to Parquet with Hugging Face Buckets, Webhooks & Jobs
The video demonstrates setting up a webhook on Hugging Face Storage Buckets to automatically trigger a Job that runs a uv script converting CSV to Parquet and writing to another bucket. The novelty is processing files without downloading, useful for data engineers automating pipelines.
01 ABSTRACT
The video shows an automated workflow: a webhook on a Hugging Face bucket triggers a Job that runs optimize-parquet.py to convert newly uploaded CSV to Parquet and write to an output bucket. A 10,000-row slice of NYC taxi data was uploaded, and the triggered Job completed in about 8 seconds. The author's view is that this suits data engineers already using Buckets to automate subsequent processing.
02 KEY FINDINGS
- Use hf CLI to manage Hugging Face buckets and set up a webhook to trigger a Job when a file arrives.
- The Job runs the uv script optimize-parquet.py to convert CSV to optimized Parquet format.
- A 10,000-row NYC taxi CSV was uploaded, triggering a Job that completed in about 8 seconds and output to a second bucket.
