[jira] [Updated] (PARQUET-1838) [C++] Expose an API that allows direct writing of RLE information for rep/def levels when writing parquet files

     [ https://issues.apache.org/jira/browse/PARQUET-1838?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Micah Kornfield updated PARQUET-1838:
-------------------------------------
    Description: When  writing data to parquet it can potentially be more efficient to have a direct interface to write RLE values, instead of passing the exploded int16_t* values.  (was: When reading data from parquet it can potentially be more efficient to have a direct interface to read back RLE values, instead of exploding them to int16_t)
