High availability Solr refers to the ability of a Solr cluster to provide uninterrupted service and access to data even in the face of hardware or software failures.
High availability Solr achieves this by distributing data and processing across multiple nodes in a cluster, so that if one node fails, other nodes can take over its workload seamlessly. In addition, high availability Solr involves configuring redundant hardware, such as multiple servers, power supplies, and network switches, to ensure that the failure of any one component does not bring down the entire system.
