Tell me what types of data in java are similar to the database tables, so that you can search and sort the data in RAM. I know that there are Virtual tables Mysql and Postgresql, which is suitable as an answer, but maybe there is something more suitable in terms of processing speed.

Essence - search, sort, iterate big data (from 10,000 lines) as fast as possible

    Such types, and even collections, does not exist. Look towards embedded in-memory databases.
