Deepak Majeti resolved PARQUET-576.
-----------------------------------
Resolution: Fixed
Fixed with #89
> C++: Simplify RandomAccessSource reads producing InputStream
> ------------------------------------------------------------
>
> Key: PARQUET-576
> URL: https://issues.apache.org/jira/browse/PARQUET-576
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-cpp
> Reporter: Wes McKinney
> Assignee: Deepak Majeti
>
> Presently, we have code like
> {code}
> int64_t bytes_to_read = col.meta_data.total_compressed_size;
> std::shared_ptr<Buffer> buffer = source_->ReadAt(col_start, bytes_to_read);
> if (buffer->size() < bytes_to_read) {
> throw ParquetException("Unable to read column chunk data");
> }
> std::unique_ptr<InputStream> stream(new InMemoryInputStream(buffer));
> {code}
> This seems like an leaky detail (some interfaces expect streams, not buffers)
> that could be encapsulated in the data source class. This would enable us
> later to work on "lazy" stream instances in a way that does not affect
> downstream users.
