Wes McKinney created PARQUET-1798: ------------------------------------- Summary: [C++] Review logic around automatic assignment of field_id's Key: PARQUET-1798 URL: https://issues.apache.org/jira/browse/PARQUET-1798 Project: Parquet Issue Type: Improvement Components: parquet-cpp Reporter: Wes McKinney Fix For: cpp-1.6.0
At schema deserialization (from Thrift) time, we are assigning a default field_id to the Schema node based on a depth-first ordering of notes. This means that a round trip (load, then write) will cause field_id's to be written that weren't there before. I'm not sure this is the desired behavior. We should examine this in more detail and possible change it. See also discussion in ARROW-7080 https://github.com/apache/arrow/pull/6408 -- This message was sent by Atlassian Jira (v8.3.4#803005)
