tustvold opened a new issue, #1938: URL: https://github.com/apache/arrow-rs/issues/1938
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** As discussed in #1666 not all types can be represented within a parquet schema. **Describe the solution you'd like** The consensus appears to be to: * By default faithfully round-trip the source data, performing no potentially lossy type conversion * Add a coerce_types flag that will use the arrow cast kernels to coerce incompatible types prior to writing them In particular ### Date64 If not coerce_types, write as Int64 and embed logical type in arrow schema only. Otherwise case to Date32 ### Timestamp If not coerce_types, write as is, setting LogicalType / ConvertedType only where appropriate. If coerce_types, cast to a UTC timestamp with the closest supported time unit, likely needing #1936. ### Interval If not coerce_types, write as FixedSizeBinaryArray matching the arrow representation and store logical type in arrow schema. If coerce_types, convert to the relevant parquet representation. **Describe alternatives you've considered** See #1666 -- This is an automated message from the Apache Git Service.
