"It includes solid established open source components (Presto, Elasticsearch, Lucene, Netty) and extends those with added core functionalities like read/write support, a SQL interface, a dashboard and a query console."

This makes no sense. Presto is already a SQL query engine, so what does it mean to "extend" it with a SQL interface? Furthermore, the crate.io SQL is even more limited than Presto SQL! Presto allows operations that are not in crate SQL, like joins and "create table as select".
