Dictionaries are RLE encoded in parquet, so we could theoretically preserve RLE encoding for dictionary arrays, on top of the existing logic to preserve the dictionary encoding. However, the cost and complexity of translating between the two representations is likely to negate much of the potential gains. > zlib Do you have a link for this, I'm not sure how you would reliably use the codecs internal RLE coding as it isn't guaranteed to be at a meaningful granularity for the encoded data? -- This is an automated message from the Apache Git Service.
