Abstract
The present disclosure involves systems, software, and computer implemented methods for data separation and write redirection in multi-tenancy database systems. One example method includes providing access to at least one application to a database system. A query is received from an application. A determination is made that the query is associated with a union view that provides unified access to a first read-only table in a shared database container and a first writable table in a tenant database container. A determination is made as to whether the query is a read query or a write query. In response to determining that the query is a read query, the query is processed using the union view. In response to determining that the query is a write query, the query is modified to use the first writable table and the query is processed using the writable table.
