Apache ZooKeeper features and specs

• High Availability
  ZooKeeper is designed to be highly available, with built-in redundancy and failover mechanisms that ensure minimal downtime.
• Consistency
  It follows a strict consistency model, ensuring that reads reflect the most recent writes, which is crucial for coordination and configuration management.
• Scalability
  ZooKeeper can handle a high number of read operations and can be scaled horizontally by adding more nodes to the ensemble.
• Leader Election
  ZooKeeper simplifies the implementation of leader election processes, making it easier to design fault-tolerant distributed systems.
• Cluster Management
  It aids in cluster management by providing mechanisms to track the status and configuration of nodes across a distributed system.
• Watch Mechanism
  ZooKeeper provides a watch mechanism that allows clients to be notified of data changes, helping to keep state synchronized across systems.

Possible disadvantages of Apache ZooKeeper

• Complexity
  Setting up and managing a ZooKeeper ensemble can be complex, requiring careful configuration and maintenance.
• Resource Intensive
  ZooKeeper can be resource-intensive, requiring significant memory and CPU, especially in large deployments.
• Write Performance
  While read operations are very fast, write operations can be slower due to the need to achieve consensus among ZooKeeper nodes.
• Operational Overhead
  Managing ZooKeeper involves operational overhead, including monitoring, backups, and handling node failures.
• Limited Programming Language Support
  Although ZooKeeper supports many major languages, the client libraries for some languages may not be as mature or well-supported as those for others.
• Transaction Size
  ZooKeeper is not designed for very large data or complex transactions, limiting its use cases to lightweight coordination tasks.
