[jira] [Commented] (PARQUET-494) Implement PLAIN_DICTIONARY encoding and decoding

    [ https://issues.apache.org/jira/browse/PARQUET-494?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15138158#comment-15138158 ] 

Wes McKinney commented on PARQUET-494:
--------------------------------------

Doing this will be somewhat difficult without first adding a {{DictEncoder}} (e.g. PARQUET-493). Can you let me know before you start working on this so we can coordinate? Thank you

> parquet-cpp currently only supports {{Encoding::RLE_DICTIONARY}}. Some implementations of Parquet still use {{Encoding::PLAIN_DICTIONARY}} (the dictionary indices are not RLE-encoded).
