[Deepak Majeti](https://issues.apache.org/jira/browse/PARQUET-474?#comment-15339582) / @majetideepak: ORC C++ does IO in a synchronous fashion. It's framework works in a batch manner. If I understand your requirement correctly, you want parquet-cpp to have `synchronized` IO API (eg: `ReadAt()` must be threadsafe), so that multiple client threads can share the same IO resource with internal state. In other words, you are looking at a code with a pipeline/streaming like framework. This JIRA makes sense for these cases. Some applications work in a batch manner by creating multiple instances of the IO resource. My concern is that introducing `synchronized` IO API can cause overheads for such applications. For this JIRA, can you use `if-defs` to enable/disable the synchronization ? -- This is an automated message from the Apache Git Service.
