[jira] [Created] (ARROW-18413) [C++][Parquet] FileMetaData exposes page index metadata

Gang Wu created ARROW-18413:
-------------------------------

             Summary: [C++][Parquet] FileMetaData exposes page index metadata
                 Key: ARROW-18413
                 URL: https://issues.apache.org/jira/browse/ARROW-18413
             Project: Apache Arrow
          Issue Type: Sub-task
          Components: C++, Parquet
            Reporter: Gang Wu
            Assignee: Gang Wu


Parquet ColumnChunk thrift object has recorded metadata for page index:
{quote}struct ColumnChunk {
/** File offset of ColumnChunk's OffsetIndex **/
4: optional i64 offset_index_offset

/** Size of ColumnChunk's OffsetIndex, in bytes **/
5: optional i32 offset_index_length

/** File offset of ColumnChunk's ColumnIndex **/
6: optional i64 column_index_offset

/** Size of ColumnChunk's ColumnIndex, in bytes **/
7: optional i32 column_index_length
}
{quote}
We just need to add public API to ColumnChunkMetaData to make it ready to read.
