In the previous article, we discussed cluster composition, node discovery, Master election, error detection, cluster scaling, and so on. This article focuses on analyzing consistency issues with meta updates in ES based on the previous section. To enhance our understanding, it also describes Master methods for cluster management, meta composition, storage, and other information. We will be discussing the following topics:
- How Master manages the cluster.
- Meta composition, storage, and recovery.
- ClusterState update process.
- Resolving current consistency issues.
- Summary
How Does Master Manage the Cluster
In the previous article, we introduced the ES cluster composition, how to discover the node, and Master election. So, how does the Master manage the cluster after it is successfully elected? There are several questions that need to be addressed, such as:
