Abstract
Consistent External Table Access maintains transactional consistency for queries that access external tables stored in a DBFS. This ability is achieved by bypassing the OS. One or more database processes executing a query that access an external table stored in a DBFS access the database-file table like other database tables in the DBMS that can be accessed to execute a query. Based on metadata stored in the DBMS regarding how an external table is stored in a DBFS, a DBMS is able to marshal database processes that access database-file tables directly to execute a query.
