Description

Can we support parquet files as source? Maybe we can base on this mod https://github.com/xitongsys/parquet-go or https://github.com/parquet-go/parquet-go

Contributor guide

Research direction
Investigate how the existing CSV reader is implemented in the codebase. Then study one of the suggested Parquet libraries (e.g., https://github.com/parquet go/parquet go) to read Parquet files and map their schema to Nebula Graph's schema. Implement a new reader similar to the CSV reader but for Parquet.
