Apache Druid features and specs

• Real-Time Data Ingestion
  Apache Druid supports real-time data ingestion, which allows users to immediately query and analyze freshly ingested data, making it ideal for applications that require up-to-the-minute insights.
• High Performance
  Druid is designed to provide fast query performance, especially for OLAP (Online Analytical Processing) queries. Its architecture leverages techniques like indexing, compression, and shard-based parallel processing to deliver quick results, even on large data sets.
• Scalability
  Druid's architecture allows it to scale horizontally, supporting both large amounts of data and numerous concurrent queries. This makes it suitable for systems that need to handle high scalability requirements.
• Flexible Data Exploration
  It supports complex queries, including group-bys, filters, and aggregations, which are essential for exploratory data analysis. Users can perform a wide range of data slicing and dicing operations.
• Rich Multi-Tenancy Support
  Druid supports multi-tenancy, enabling different user groups to access and query the database simultaneously without performance degradation, thus accommodating diverse data analytics requirements within the same system.

Possible disadvantages of Apache Druid

• Complex Setup and Configuration
  Setting up and configuring Apache Druid can be complex and resource-intensive. It requires a good understanding of its architecture and components, which may pose a steep learning curve for beginners.
• Resource Heavy
  Druid can be resource-intensive, often requiring significant CPU, memory, and disk resources, especially when handling large scale data and high query loads. This can result in increased infrastructure costs.
• Limited Transactional Support
  Druid is not designed for transactional workloads and lacks full ACID compliance. It is optimized for read-heavy analytical queries rather than write-heavy transactional operations.
• Complexity in Handling Updates
  Updating or deleting existing records in Druid is not straightforward and often involves re-indexing data. This can complicate use cases where mutable data is a common requirement.
• Limited Tooling and Ecosystem
  Compared to more established databases and analytical engines, Druid's ecosystem and available tooling for development, monitoring, and management might be less extensive, potentially requiring custom solutions.
