If you stick to the Utf8 datatype for `market`, the automatic dict encoding done by the parquet writer works. So assume some operation is not properly merging the dict keys. The weird thing is that this only happens with 10m rows not with 1m even if all rows in the sample file have a market set. -- This is an automated message from the Apache Git Service.
