--------------------------------------
Summary: [C++] Incompatibility due to moving from Parquet to Arrow
IO interfaces
Key: PARQUET-1636
URL: https://issues.apache.org/jira/browse/PARQUET-1636
Project: Parquet
Issue Type: Improvement
Components: parquet-cpp
Reporter: Deepak Majeti
Assignee: Wes McKinney
We moved to the Arrow IO interfaces as part of
https://issues.apache.org/jira/browse/PARQUET-1422
However, the BufferedInputStream implementations between Parquet and Arrow are
different.
Parquet's BufferedInputStream used to takes a RandomAccessSource. Arrow's
implementation takes an InputStream. As a result, the
{{::arrow::io::BufferedInputStream::Peek(which invokes Read())}} implementation
causes the raw source (input to {{BufferedInputStream}}) to change its offset
on Peek(). This did not happen in the Parquet's BufferedInputStream
implementation.
