[jira] [Commented] (PARQUET-1014) Example for multiple row group writer (cpp)

["Deepak Majeti (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PARQUET-1014?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16033781#comment-16033781 ] 

Deepak Majeti commented on PARQUET-1014:
----------------------------------------

Hi [~elderrex],
The example at {{examples/reader-writer.cc:}} adds a single rowgroup. To add another rowgroup, you just need to call {{file_writer->AppendRowGroup(NUM_ROWS_PER_ROW_GROUP)}} at {{examples/reader-writer.cc:123}} again.

You will need def/rep levels for all types including the primitive types like int64_t.

Do you have a reproducer for the crash?
Thanks!
