Hey when I use Java API to get info request it return value for the request but it not include value for the “memory_data_bytes”

The memory_data_bytes metric indicates the amount of record data that is stored in memory (does not include the index entry). So I suspect this namespace isn’t data-in-memory.

There isn’t a metric for either cumulative or index memory usage at the set level. They can be accessed at the namespace level, see memory_used_bytes.
