Hi, I'm currently saving JSON in pure String format in the value cell and depends on HBase' block compression to reduce the overhead of JSON.
I'm wondering if there's a more space efficient way to store JSON? (there're lots of 0s and 1s, JSON String actually is an OK format) I want to keep the value as a Map since the schema of source data might change over time. Also is there a DIFF based encoding for values? Since I'm storing historical data (snapshot data) and changes between adjacent value cells are relatively small.
