Cache Messages with Singleton Pipes and Using Pipes for Persistent Messaging

On Autonomous Database the DBMS_PIPE package includes support for Singleton Pipes and Persistent Messaging Pipes.

• Singleton Pipes allow you to cache and retrieve a custom message and share the message across multiple database sessions with concurrent reads.

• Persistent Messaging Pipes allow you to store messages in Cloud Object Storage. Using persistent messages you can send and receive messages within a single database or between multiple databases in the same or in different regions, without message size limitations.

• Cache Messages with Singleton Pipes
  Singleton Pipe is an addition to the DBMS_PIPE package that allows you to cache and retrieve a custom message and share the message across multiple database sessions with concurrent reads.
• Use Persistent Messaging with Messages Stored in Cloud Object Store
  The DBMS_PIPE package has extended functionality on Autonomous Database to support persistent messaging, where messages are stored in Cloud Object Store.
