Wes McKinney commented on PARQUET-1636: --------------------------------------- I just created https://issues.apache.org/jira/browse/ARROW-6180, that might be a solution if your problem results from multithreading > [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 > Priority: Major > > 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, theĀ > {{::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. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
