When users schedule EXPORT PARTITION with output_format_parquet_row_group_size_bytes (for example to avoid the default 512 MiB cap), this manifest only captures output_format_parquet_row_group_size; the background export context is rebuilt from the manifest, and getFormatSettings consumes both output_format_parquet_row_group_size and output_format_parquet_row_group_size_bytes (src/Formats/FormatFactory.cpp:202-203). Any worker replica will therefore fall back to its default byte limit and produce different row groups than the initiating query. Please persist and restore output_format_parquet_row_group_size_bytes alongside this field.
