Apache Pig features and specs

• Simplicity
  Apache Pig provides a high-level scripting language called Pig Latin that is much easier to write and understand than complex MapReduce code, enabling faster development time.
• Abstracts Hadoop Complexity
  Pig abstracts the complexity of Hadoop, allowing developers to focus on data processing rather than worrying about the intricacies of Hadoop’s underlying mechanisms.
• Extensibility
  Pig allows user-defined functions (UDFs) to process various types of data, giving users the flexibility to extend its functionality according to their specific requirements.
• Optimized Query Execution
  Pig includes a rich set of optimization techniques that automatically optimize the execution of scripts, thereby improving performance without needing manual tuning.
• Error Handling and Debugging
  The platform has an extensive error handling mechanism and provides the ability to make debugging easier through logging and stack traces, making it simpler to troubleshoot issues.

Possible disadvantages of Apache Pig

• Performance Limitations
  While Pig simplifies writing MapReduce operations, it may not always offer the same level of performance as hand-optimized, low-level MapReduce code.
• Limited Real-Time Processing
  Pig is primarily designed for batch processing and may not be the best choice for real-time data processing requirements.
• Steeper Learning Curve for SQL Users
  Developers who are already familiar with SQL might find Pig Latin to be less intuitive at first, resulting in a steeper learning curve for building complex data transformations.
• Maintenance Overhead
  As Pig scripts grow in complexity and number, maintaining and managing these scripts can become challenging, particularly in large-scale production environments.
• Growing Obsolescence
  With the rise of more versatile and performant Big Data tools like Apache Spark and Hive, Pig’s relevance and community support have been on the decline.

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.
