# ClickHouse Parquet reader doesn't support such complex types, so I didn't burrow into the issue.

# Strange behaviour for repeated_no_annotation.parquet around __buitin_expect, so this file was disabled:

# release:
#   Code: 349. DB::Ex---tion: Can not insert NULL data into non-nullable column "phoneNumbers": data for INSERT was parsed from stdin
