What data update interval is achieved using a Slave database in a Master-Slave architecture?

In a Master-Slave architecture, the Slave database is updated asynchronously relative to the Master. This means that data on the Slave is replicated with some delay, depending on the replication settings and system load. The update interval is not fixed and can vary from a few milliseconds to several seconds or even minutes. It is important to understand that the Slave may have outdated data compared to the Master, which affects read consistency.
