If we move stats collection into Iceberg, we could do this automatically.

Could you also add information to the documentation ?

We also need to document iceberg.extended-statistics.enabled before we document iceberg.extended-statistics.collect-on-write. Let's follow-up

Note that Delta's delta.extended-statistics.collect-on-write isn't documented either, so you may want to document it.

This doesn't seem like a safe assumption, unless I'm missing something.

You're walking the snapshot history back until you find all the columns you're looking for so you may find duplicates for the columns you did find already.

Get bytes from ByteBuffer safely
3afebac 
`ByteBuffer.array()` is a convenient and efficient way to get bytes from
a `ByteBuffer`. It has, however, numerous preconditions that should be
checked before using the returned array. The commit replaces all
`ByteBuffer.array()` usages where these preconditions are assumed to be
true.
@findepi
Improve assertions in testCleaningUpWithTableWithSpecifiedLocation
caa5ef3 
- prefer `assertThat(List).hasSize` to `assertThat(list.size())` as the
  former includes list's elements upon failure,
- drop table after test.
@findepi
Fix metadata file listing in testCleaningUpWithTableWithSpecifiedLoca…
114853e 
…tion

Before the change, the test used `getAllMetadataFilesFromTableDirectory`
utility, but it was listing all (metadata and data) files. Similar
method, `getAllMetadataFilesFromTableDirectoryForTable`, listing only
metadata files existed, but was not used in the test.

The change merges the utility methods: the correct logic comes from
`getAllMetadataFilesFromTableDirectoryForTable` (so no behavior change
for tests other than `testCleaningUpWithTableWithSpecifiedLocation`),
and the name comes from `getAllMetadataFilesFromTableDirectory`.
@findepi
Rename test class to contain more scenarios
c798729 
Iceberg connector will collect stats during writes, and it would be good
to test this together with ANALYZE. Rename class to contain all related
functionalities.

This is much nicer :) But just wanted to point out that the preferred romanization is "Kyiv". Sadly, there's no timezone "Europe/Kyiv".
