Hi Shelton, Thanks for your reply, but INVALIDATE METADATA didn't work for me. I still have the same error. My option was to recreate the table with a CREATE TABLE as SELECT from the previous table. Thanks again

Hi, @zhxj, do you found some way to treat this issue? I have the same issue to convert timestamp data to Parquet. I try this in the schema, but do not work. { "name": "dat_timestamp", "type": { "type":"int64", "logicalType":"timestamp-millis", "isAdjustedToUTC" : "false"} }, Thanks,

Maybe do you are looking for SSoT (Single Source of Thruth). Kafka may be the best option to achieve this concept. The link bellow may help you: https://www.confluent.io/blog/messaging-single-source-truth/

After read the content of the link below a made some changes in both nifi.properties e boostrap.conf files.
