Zed can't read Parquet output from DuckDB

[philrz]

Repro is with Zed commit 0a375f8. The test data originally came from a community user that reported brimdata/zui#2751 and brimdata/zui#2754.

Start with the attached test data imdb.csv.

$ zq -version
Version: v1.7.0-28-g0a375f88

$ zq -z 'count()' imdb.csv 
347(uint64)

A user imports it into DuckDB as a table and then exports that table as Parquet.

$ duckdb
v0.7.1 b00b93f0b1
Enter ".help" for usage hints.
Connected to a transient in-memory database.
Use ".open FILENAME" to reopen on a persistent database.

D create table imdb as select * from 'imdb.csv';
D copy imdb to 'output.parquet' (FORMAT PARQUET);

Zed cannot read the Parquet that was produced.

$ zq -i parquet output.parquet 
output.parquet: *parquet.PageHeader field 15 read error: don't know what type: 13

However, tools like https://parquetreader.com seem able to read it without complaint.

I know we've suspected that following through on #4278 may allow us to cover more Parquet dialects, so I'll mark this issue as dependent on that one just in case that alone fixes it.

Verified in Zed commit deea4a4.

The Parquet format that's output by DuckDB is now readable.

$ zq -version

$ zq -i parquet output.parquet
