Thank you for the contribution @Syleechan . I think we can avoid the new dependency but otherwise this looks great

I think we can avoid this new dependency by either reusing our existing implementation (see below)
# Conflicts: # datafusion/proto/proto/datafusion.proto # datafusion/proto/src/generated/pbjson.rs # datafusion/proto/src/generated/prost.rs # datafusion/proto/src/logical_plan/from_proto.rs

@alamb thanks, I have changed to use exsiting implementation. But the code checks maybe something wrong, I have used the checking command to run local all have passed. |

I believe the failures are due to some logical conflicts since fixed in #8187 Updating to the latest main should work I think |

@alamb thanks, it works. And wait for your code review. |
