Re: XOR encoding for floating point

Hi Jacky Li, XOR Encoding mainly works on timeseries data as discussed in the paper. We looked into the classes suggested by you and found out that we will be having min and max values for our data, firstly we need to identify whether the data is in time series or not only then XOR encoding can be

Re: XOR encoding for floating point

+1 Feel free to contribute :) To implement this feature, I think you need to break this feature into following sub tasks. 1. You can extend ColumnPageCodec to implement XOR encoding. 2. Come up with the criteria of how to select this encoding and change behavior of DefaultEncodingStrategy 3. SQL

XOR encoding for floating point

Hi Community, I was looking into CARBONDATA-1128 . The document attached with the Jira describes about compression of timestamp and decimal values. The decimal values are compressed using XOR. So I would like to contribute to one of its subtas
