Datafusion integration assumes table's data files are local

9

The Datafusion integration passes a list of file paths representing a table's actual data to Datafusion's ParquetExec, but if the Delta table's StorageBackend is anything other than the FileStorageBackend then...

tonic-health: check in generated code instead of requiring tonic-build

3

## Feature Request As the author of a library/SDK that provides convenience wrappers over gRPC definitions, it'd be great if tonic-health didn't require `protoc` to compile, by checking in the...

CallResource: don't set Content-Type header if status is 204

3

Grafana's HTTPServer ensures that the Content-Type header is always set in the response to a CallResource call, but when the status code is 204 No Content this shouldn't be done;...

Allow columns to be selected using regular expressions

12

This allows a selector such as r'a[bc]?' to be used, which would select columns 'a', 'ab', 'ac' but not 'ad'. This can be used in the 'xsv select' command as...

Select columns based on regex

4

I have a pretty unwieldy CSV file with a ton of columns (~300000) all with quite long column names. I'd really like to be able to select the columns using...

Feature: reshape data

5

I think it'd great to be able to reshape data in a similar fashion to: - the [`reshape` verb of Miller](https://johnkerl.org/miller/doc/reference-verbs.html#reshape) - the [`dcast.data.table`](https://www.rdocumentation.org/packages/data.table/versions/1.12.2/topics/dcast.data.table) and [`melt.data.table`](https://www.rdocumentation.org/packages/data.table/versions/1.12.2/topics/melt.data.table) functions of R's `data.table`...

Custom collector for multiple metrics

Hi! I've been looking at implementing a Prometheus collector for the recently announced [tokio-metrics](https://docs.rs/tokio-metrics/latest/tokio_metrics/index.html) crate. Every scrape, I'd like to gather runtime metrics for the currently Tokio runtime. The problem...

It looks like this is being bashed around by the code generation: it was removed in #200, re-added in #266, then removed again by #325. I'm not sure how the...

`sink_parquet` doesn't work on LazyFrames created by `scan_ndjson`

4

### Problem description The following code gives a (slightly confusing) error: ```python pl.scan_ndjson(input_file).sink_parquet(output_file) # thread '' panicked at /Users/ben/repos/rust/polars/crates/polars-lazy/src/physical_plan/planner/lp.rs:153:28: # sink_parquet not yet supported in standard engine. Use 'collect().write_parquet()' #...

The polls over time graph currently just shows the latest value of the 'polls' field, which is effectively a counter, so it just increases forever. It would be much more...
