srilman opened a new pull request, #1832:
URL: https://github.com/apache/iceberg-python/pull/1832
Closes #1778.
# Rationale for this change
Current, filters that are applied to the top-level struct column do not
work. For example, given a table of schema:
```
table {
2: id: optional int
1: data: required string
3: location: struct<5: latitude: optional float, 6: longitude: optional
float>
}
```
We want to support applying filters to field `location`, such as `location
is not null`. Note that filters like `location == {"latitude": ...,
"longitude": ...}` wont work right now, but can be equivalently rewritten to
`location.latitude == ... and location.longitude == ...`.
# Are these changes tested?
Yes, tests were added at both the schema level and table reads.
# Are there any user-facing changes?
Support some basic filters on struct columns at the top-level.
