location on a separate server.replicas can be kept in sync with the source data continuously or at scheduled intervals. One-way synchronization and bidirectional synchronization are possible. Replication can even be used to keep several datasets in sync with each other. at the first level, I'll cover basic replication components and describe how they work together to replicate data and change data. We'll also look at a detailed example of setting up a simple replication scenario. Replication

available CPUs, so you can feel the concurrency attribute regardless of the number of worker threads configured.
If the number of worker threads is configured to be greater than the default, it will almost always reverse and degrade performance due to scheduling and resource overhead problems. This should be done only in very special circumstances, and when rigorous systematic testing shows that this setting is helpful.

There are many reasons for slow query speed. The following are common causes:
1. No index or no index is used (this is the most common problem of slow query and is a defect in programming)
2. Low I/O throughput, resulting in a bottleneck effect.
3. the query is not optimized because no computing column is created.
