Should we change this in Loc 880?

The line 320 in the parquet.rst doc should also be changed.

public abstract class ConversionPatterns {

  static final String MAP_REPEATED_NAME = "key_value";
  private static final String ELEMENT_NAME = "element";

Go through the Java code, seems that it also uses "element". LGTM

In C++, code shows force. But when I go through code in arrow-rs, it doesn't say is force. And though parquet-format use "element" in description, it doesn't says it's forced. Maybe we should ask the parquet maillist later?

The rules were laid out earlier here:

https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#backward-compatibility-rules

Before this PR I did work to make sure that the Arrow C++ implementation (1) didn't care about the field names in equality comparison (PR) and (2) could cheaply cast between types that differed only in field names (PR).

Thanks! So, this flag could make converting and reading a bit cheaper?

[BUG] Raise error when Ray Data tensor cannot be pickled and disable …
b7e6e41 
…compliant nested types (#2428)

This solves some of our flaky unit tests that try to read a Ray dataset
tensor type under a Pyarrow version that does not properly serialize it.
Adds a new exception when we detect this issue, and also updates our
pyarrow dependencies to 13.0.0.

I also found a separate bug upon upgrading to pyarrow, where versions >=
13.0.0 will use compliant Parquet nested type names by default (see
apache/arrow#35146), which would then cause a
discrepancy between the Parquet and Arrow schemas for extension types.
This would lead to incorrect conversion from Parquet to Arrow when we
would read a file. This PR disables that explicitly.

Finally I also added a `coerce_temporal_nanoseconds` parameter to
`to_pandas` to revert it to its pre pyarrow>=13.0.0 behavior, which
makes the sql integration tests pass again

Confirmed to raise proper error in local testing
