Apache Kylin features and specs

• High Query Performance
  Apache Kylin is designed for high-performance, low-latency analytics on large datasets. Its OLAP engine pre-computes and stores aggregated queries, which speeds up query responses significantly.
• Scalability
  Kylin can handle massive volumes of data, making it suitable for large scale data warehousing needs. It is designed to scale out by distributing the workload across a cluster of servers.
• Integration with Hadoop Ecosystem
  Kylin integrates seamlessly with the Hadoop ecosystem, leveraging tools like Hive, HBase, and Spark to facilitate data processing and storage, thereby enhancing its functionality and compatibility.
• Support for Multi-dimensional Analysis
  It provides strong multidimensional analysis capabilities, allowing for complex queries using well-known BI tools like Tableau and Power BI.

Possible disadvantages of Apache Kylin

• Complex Setup
  Setting up and configuring Apache Kylin can be complex and time-consuming, requiring a deep understanding of the Hadoop ecosystem and its components.
• Resource Intensity
  The pre-computation of data cubes and their storage can be resource-intensive, consuming significant memory and storage capacity.
• Limited Flexibility in Querying
  Pre-aggregated cube-based analysis may not cover all ad-hoc queries. Kylin's strength lies in pre-aggregated queries but may fall short in handling highly dynamic, on-the-fly queries.
• Maintenance Overhead
  Maintaining Kylin’s precomputed cubes can become cumbersome, particularly as data evolves or changes frequently, requiring updates or recalculations of cubes.

Google BigQuery features and specs

• Scalability
  BigQuery can effortlessly scale to handle large volumes of data due to its serverless architecture, thereby reducing the operational overhead of managing infrastructure.
• Speed
  It leverages Google's infrastructure to provide high-speed data processing, making it possible to run complex queries on massive datasets in a matter of seconds.
• Integrations
  BigQuery easily integrates with various Google Cloud Platform services, as well as other popular data tools like Looker, Tableau, and Power BI.
• Automatic Optimization
  Features like automatic data partitioning and clustering help to optimize query performance without requiring manual tuning.
• Security
  BigQuery provides robust security features including IAM roles, customer-managed encryption keys, and detailed audit logging.
• Cost Efficiency
  The pricing model is based on the amount of data processed, which can be cost-effective for many use cases when compared to traditional data warehouses.
• Managed Service
  Being fully managed, BigQuery takes care of database administration tasks such as scaling, backups, and patch management, allowing users to focus on their data and queries.

Possible disadvantages of Google BigQuery

• Cost Predictability
  While the pay-per-use model can be cost-efficient, it can also make cost forecasting difficult. Unexpected large queries could lead to higher-than-anticipated costs.
• Complexity
  The learning curve can be steep for those who are not already familiar with SQL or Google Cloud Platform, potentially requiring training and education.
• Limited Updates
  BigQuery is optimized for read-heavy operations, and it can be less efficient for scenarios that require frequent updates or deletions of data.
• Query Pricing
  Costs are based on the amount of data processed by each query, which may not be suitable for use cases that require frequent analysis of large datasets.
• Data Transfer Costs
  While internal data movement within Google Cloud can be cost-effective, transferring data to or from other services or on-premises systems can incur additional costs.
• Dependency on Google Cloud
  Organizations heavily invested in multi-cloud or hybrid-cloud strategies may find the dependency on Google Cloud limiting.
• Cold Data Performance
  Query performance might be slower for so-called 'cold data,' or data that has not been queried recently, affecting the responsiveness for some workloads.
