6 Cons of Google BigQuery

• Steep learning curve: While BigQuery offers powerful capabilities, it can have a steep learning curve for users who are not familiar with cloud-based data analytics platforms. Users may need to invest time in understanding the query syntax and optimizing queries for performance.
• Complex data modeling: BigQuery is a schema-less data warehouse, which means managing complex data models and relationships can be challenging. Designing efficient data models requires careful planning and understanding of the data structure.
• Data movement costs: If you need to move data from external sources to BigQuery, there might be additional costs associated with data transfer. This can be a consideration if you have large volumes of data or frequent data updates.
• Data size limitations: While BigQuery can handle massive amounts of data, there are certain limitations on individual table and query sizes. For example, a single query cannot process more than 100 TB of data, and a single table cannot exceed 20,000 columns.
• Limited support for transactional operations: BigQuery is optimized for analytics workloads and doesn’t provide full support for transactional operations like traditional relational databases. It may not be suitable for use cases that require complex transaction processing or real-time data updates.
• Dependency on internet connectivity: As a cloud-based service, BigQuery relies on a stable internet connection for access and data transfer. In case of network disruptions or limited connectivity, it can impact the availability and performance of your queries.

Cases when Google BigQuery does not work

1. Insufficient Data: Google BigQuery is designed to handle large volumes of data efficiently. However, if you have a very small dataset with just a few rows or a low volume of data, BigQuery may not be the most cost-effective or efficient solution for your needs. In such cases, using a traditional database or other data processing tools might be more appropriate.
2. Complex Transactional Workloads: BigQuery is primarily built for analytical workloads rather than handling complex transactional operations. If your use case involves frequent updates, inserts, or deletes on individual rows, you might find that a traditional relational database management system (RDBMS) like MySQL or PostgreSQL is better suited for your requirements.
3. Real-Time Data Processing: Although BigQuery offers high-speed querying capabilities, it is not designed for real-time data processing. If your use case demands immediate or near-real-time analysis of streaming data, you might want to explore other technologies like Apache Kafka, Apache Flink, or Google Cloud Dataflow.
4. High Latency Tolerance: While BigQuery provides impressive scalability and parallelism for processing large datasets, it is not optimized for low-latency queries. If your application requires sub-second response times, consider using an in-memory database or a caching layer to improve query performance.
5. Strict Data Consistency Requirements: BigQuery is a distributed system that uses eventual consistency, which means it does not guarantee strong data consistency at all times. If your use case relies heavily on strict data consistency, consider using a traditional RDBMS that provides ACID (Atomicity, Consistency, Isolation, Durability) guarantees.
6. Limited Control Over Infrastructure: BigQuery is a fully managed service offered by Google Cloud, which means you have limited control over the underlying infrastructure. If your use case requires fine-grained control over hardware configurations, operating systems, or network settings, you might prefer managing your own infrastructure using tools like Apache Hadoop or Apache Spark.
7. High Cost for Small Workloads: While BigQuery is cost-effective for large-scale data processing, it may not be the most economical option for small workloads or sporadic queries. If you have a low volume of data or infrequent analytical needs, consider using on-demand pricing or exploring alternative solutions like Google Cloud Dataprep or Google Sheets.
8. Data Privacy and Compliance: If your data has strict privacy or compliance requirements, such as HIPAA or GDPR, you need to ensure that BigQuery meets all the necessary security and compliance standards. While Google Cloud provides robust security measures, you should carefully evaluate the specific data protection requirements for your use case.
