DataFrames & Big Data
Data and analytics skill, available on Zeplik
DataFrames & Big Data is a ready-to-run data and analytics skill on Zeplik. Fast and out-of-core dataframes — Polars (Arrow), Vaex for billion-row datasets, and Zarr chunked N-D arrays for cloud storage. Ask in plain language and Zeplik applies the skill's method for you inside the conversation, on whichever AI model you prefer.
The DataFrames & Big Data skill loads automatically when your request matches it, or you can invoke it directly by typing /dataframe-big-data in any chat. It works with attachments, connectors, and any model that supports the task, so you get the same expert method every time without setting anything up.
What the DataFrames & Big Data skill can do
- Process billion-row datasets efficiently with Vaex out-of-core dataframes
- Write fast Arrow-backed dataframe code using Polars
- Read and write chunked N-D arrays with Zarr for cloud storage
- Recommend the right library based on data size and access pattern

How the DataFrames & Big Data skill works
/dataframe-big-data
Umbrella for dataframes and big data. The user has large tabular or array data; establish the size and access pattern, pick the library, and deliver efficient processing code. For statistical modeling on the data route to statistical-ml-python.
Dispatch table
Pick the reference file(s) that match the request, read them, then answer. Read at most 2-3 files per turn.
| Topic | Read |
|---|---|
| Fast DataFrame library (Apache Arrow). | references/polars.md |
| Use this skill for processing and analyzing large tabular datasets (billions of rows) t… | references/vaex.md |
| Chunked N-D arrays for cloud storage. | references/zarr-python.md |
How to work
- Identify which leaf topic the request maps to from the dispatch table above; establish the concrete inputs (language, dataset, framework, file format) and the goal. Ask for a missing detail rather than guessing.
- Read the matching reference file(s) before answering. Read at most 2-3 per turn.
- Deliver runnable artifacts — code, configs, specs — with a short rationale, matching the user's existing conventions when they paste code.
- Confirm any decision the source flags (versions, thresholds, tradeoffs) with the user instead of guessing.
