如何在Java的rocksDB中写入列数据？

Question

How do you write data in column format in rocksdb.

Example of columns can be Id, state, URL, fieldNames, query ;

I should be able to read all data giving Id .

Answer 1

RocksDB is a key value store, so it doesn't have the concept of columns. What you can do, is to store a serialized object as value, which in your example would contain eg state, url, fieldnames and query, and use the id as key.
