Redis redis-check-rdb should parse rdb part by part instead of loafing entire file in memory

If I have a large RDB file, say 20GB, which I want to check using redis-check-rdb then it would require me to have a server with memory more than the size of the file as redis-check-rdb loads the entire file in memory. Instead, it would be great if the redis-check-rdb utility can parse the RDB file in chunks and display the results or use some other smarter way than loading the entire file in memory.
