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.
