[Xuwei Fu](https://issues.apache.org/jira/browse/PARQUET-2222?#comment-17730992) / @mapleFU: @gszadovszky Hi Gabor maybe I'm misleading. 1. RLE for Boolean is just implemented a few month ago by me. I guess Legacy writer cannot write use RLE. 2. For RL/DL, in parquet-cpp, only RLE can be used. In arrow-rs, I found the code below ```Java /// RLE/Bit-Packing hybrid encoding for values. /// Currently is used only for data pages v2 and supports boolean types. pub struct RleValueEncoder<T: DataType> { // Buffer with raw values that we collect, // when flushing buffer they are encoded using RLE encoder encoder: Option<RleEncoder>, _phantom: PhantomData<T>, } ``` I guess it only supports Page V2 and format V2. @tustvold am I right? -- This is an automated message from the Apache Git Service.
