Description

Currently, exception stacktrace is logged at warn level if an offset index is missing. Also a warn level log happens if a column index is missing which is required for column-index based filtering. Both cases are properly valid scenarios if the file is written by older libraries (where no column/offset indexes are written at all) or the sorting order is undefined for the related column type (e.g. INT96).
These logs shall be kept at INFO level and no stacktrace shall be provided.
