BigQuery is a serverless, scalable cloud-based data warehouse provided by Google Cloud Platform. It is a fully managed warehouse that allows users to perform ETL on the data with the help of SQL queries. You can unleash the power of SQL and the performance and scalability feature of Google Cloud Platform to perform ad-hoc analytics on your data. BigQuery can load a massive amount of data in near real-time.

Key Features of BigQuery

Some of the key features of Google BigQuery are listed below:

  1. Scalable Architecture: BigQuery offers a petabyte scalable architecture, and is straightforward to scale as per needs. 
  2. Faster Processing: BigQuery can execute SQL queries over petabytes of data in seconds. You can run analysis over millions of rows without worrying about scalability.
  3. Fully Managed: BigQuery is a fully managed and serverless architecture. It automatically manages the up-scale or down-scale of the cluster.
  4. Security: BigQuery provides the safety of sensitive data when data is in in-flight as well as at rest. The tables and the data are compressed and encrypted to ensure the utmost security.
  5. Real-time data ingestion: BigQuery can perform real-time data analysis, thereby making it famous across all the IoT and Transaction platforms.
  6. Fault Tolerance: BigQuery offers replication that replicates data across multiple zones or multiple regions. It ensures consistent data availability when the region/zones go down.

What is ETL?

ETL is an abbreviation for Extract, Transform, and Loading. With the introduction of cloud technologies, many organizations are trying to perform ETL to migrate their data. They often have data storage as an RDBMS or legacy system which lacks performance, scalability, and fault-tolerant systems. Hence, to get all these features, organizations are migrating data to cloud technologies, like the Google cloud platform.

As the ability of businesses to collect data explodes, data teams have a crucial role to play in fueling data-driven decisions. Yet, they struggle to consolidate the data scattered across sources into their warehouse to build a single source of truth. Broken pipelines, data quality issues, bugs and errors, and lack of control and visibility over the data flow make data integration a nightmare.

1000+ data teams rely on Hevo’s Data Pipeline Platform to integrate data from over 150+ sources in a matter of minutes. Billions of data events from sources as varied as SaaS apps, Databases, File Storage and Streaming sources can be replicated in near real-time with Hevo’s fault-tolerant architecture.

What’s more – Hevo puts complete control in the hands of data teams with intuitive dashboards for pipeline monitoring, auto-schema management, and custom ingestion/loading schedules.
