Apache Kudu features and specs

• Fast Analytics on Fresh Data
  Kudu is designed for fast analytical processing on up-to-date data. It allows for efficient columnar storage which enables quick read and write capabilities suitable for real-time analytics.
• Hybrid Workloads
  Supports hybrid workloads of both analytical and transactional processing, making it versatile for use cases that require both types of operations.
• Seamless Integration
  Integrates well with the Apache ecosystem, particularly with Apache Hadoop, Apache Impala, and Apache Spark, enabling a cohesive environment for data processing and management.
• Fine-grained Updates
  Allows for efficient updates to individual columns and rows, which is useful for applications that require frequent updates alongside analytic capabilities.
• Schema Evolution
  Supports schema evolution, which allows for adding, dropping, and renaming columns without costly table rewrites.

Possible disadvantages of Apache Kudu

• Complexity in Installation and Configuration
  The setup and configuration of Kudu can be complex, requiring a good understanding of its architecture and dependencies.
• Limited SQL Support
  While Kudu is optimized for analytical tasks, its SQL capabilities are limited compared to some traditional RDBMS systems, which might require additional tools for more complex queries.
• Community and Ecosystem
  Although growing, the community and ecosystem around Kudu are smaller compared to more established systems, which may result in less available resources and third-party tools.
• Memory Intensive
  Kudu can be memory-intensive, which might require more hardware resources compared to other systems, especially as data volumes grow.
• Write Performance Limitations
  While Kudu offers fast reads, its write performance can be slower compared to systems specifically optimized for high-speed transactional processing.
