Applies to apps that need to provide

predefined queries and perform data statistics when there are few data changes. Applicable to applications that require data version support. For example:CRM and CMS systems. Master-master replication is very useful for multi-site deployment. Note: master-master replication is a database synchronization method that allows data to be shared among a group of computers and any member in the group to update th

Cassandra Best Application Scenario: When the write operation is used more than the read operation (record the log), if every system build must be written in Java (no one is fired because Apache software is used) For example, the banking industry, the US space, and the financial industry (although not essential for financial transactions, these industries have more database requirements than they do) write faster than read, therefore, a natural fe
