Hi! I get this error on select query from table (partition by day) with partitions located on s3:

Received exception from server (version 21.12.3):
Code: 33. DB::Exception: Received from localhost:9000. DB::Exception: Received from chi-tesseract-01-tesseract-3-0:9000. DB::Exception: Cannot read all data. Bytes read: 0. Bytes expected: 8.: (while reading column ContainerName): (while reading from part /var/lib/clickhouse/disks/s3/data/flamedb/%2Einner%2Esamples_1day_local/20211230_0_139593_10/ from mark 32039 with max_rows_to_read = 8192): While executing MergeTreeThread. (CANNOT_READ_ALL_DATA)

column ContainerName is LowCardinality, so my question is my issue relevant to this bugfix?

Absolutely, this fix is exactly for your issue.
