---------------------------------------
Summary: Write new logical types in Parquet
Key: IMPALA-7889
URL: https://issues.apache.org/jira/browse/IMPALA-7889
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Csaba Ringhofer
Assignee: Csaba Ringhofer
Parquet added LogicalTypeAnnotation as a new way to express metadata about
columns. For types that already exist, the old way (ConvertedType) should be
also written to remain compatible with older readers, but new types (like int64
nano) are only added as LogicalTypeAnnotation.
