I am 100% new to Yugabyte but it seems incredibly promising. I have some questions I cannot quite find the answer to. Does Yugabyte separate the YCQL databases from the YSQL built databases? Can I access the NoSQL YCQL built keyspaces and tables using YSQL?

I am a novice. It seems like the keyspace=database and the table would live in the public schema if so but I cannot seem to find the table.

Thanks.

Hi @asevans48

The layers are separate and you cannot read data from each other. You need YSQL client for YSQL data and YCQL client for YCQL data.

You can subscribe to [[YSQL] Access YCQL tables via the YSQL API · Issue #830 · yugabyte/yugabyte-db · GitHub](https://github.com/yugabyte/yugabyte-db/issues/830) to be notified on changes.
