Cannot use Snappy decompression

[mdrach]

Apologies if this is a silly question; if so point me to the docs that have the answer. I'm trying to run the example that reads a parquet file with snappy decompression. I get the following error.

Error: External("", General("Compression Snappy is not installed"))

I'm on OSX 11.6.1 and I've installed snappy though I'm not sure this is even necessary given that parquet2 uses snap.

I've attached a minimal project that produces this error: test_parquet_snappy.zip

Any pointers here? Thanks.

Hi, you need to use the feature io_parquet_compression - essentially we offer the possibility to not drag dependencies if the user does not want them and these are some of them. Note that you do not need snappy installed on your machine.

Perhaps the error message could be more actionable? Like something along the lines of Feature compression Snappy is not enabled

I agree. This requires a small surgery to parquet2: jorgecarleitao/parquet2#69 so that we can match the error and propagate it on our end.

Ok, there is now a PR to fix this :)
