  Key Concepts: 
  A hot standby database is a type of database replication that allows for a secondary database to be kept in sync with the primary database. This ensures that if the primary database fails, the secondary database can be used as a backup. The hot standby database is kept up-to-date with the primary database by continuously replicating changes from the primary to the secondary. 
  
  How to use it: 
  In order to use a hot standby database, you must first configure the primary and secondary databases. This involves setting up replication between the two databases and ensuring that all changes made to the primary are replicated to the secondary. Once this is done, you can then use the hot standby database as a backup in case of failure of the primary. 
  
  Tips & Tricks: 
  When configuring a hot standby database, it is important to ensure that all changes made to the primary are replicated to the secondary. This can be done by setting up replication between the two databases and ensuring that all changes are replicated in real-time. Additionally, it is important to regularly test the hot standby database to ensure that it is working properly and that all changes are being replicated correctly.
