Choosing the right database is a critical choice when building any software application. All databases have different strengths and weaknesses when it comes to performance, so deciding which database has the most benefits and the most minor downsides for your specific use case and data model is an important decision. Below you will find an overview of the key concepts, architecture, features, use cases, and pricing models of Google BigQuery and Datadog so you can quickly see how they compare against each other.

The primary purpose of this article is to compare how Google BigQuery and Datadog perform for workloads involving time series data, not for all possible use cases. Time series data typically presents a unique challenge in terms of database performance. This is due to the high volume of data being written and the query patterns to access that data. This article doesn’t intend to make the case for which database is better; it simply provides an overview of each database so you can make an informed decision.

Google BigQuery Overview

Google BigQuery is a fully-managed, serverless data warehouse and analytics platform developed by Google Cloud. Launched in 2011, BigQuery is designed to handle large-scale data processing and querying, enabling users to analyze massive datasets in real-time. With a focus on performance, scalability, and ease of use, BigQuery is suitable for a wide range of data analytics use cases, including business intelligence, log analysis, and machine learning.

Datadog Overview

Datadog is a monitoring and analytics platform that integrates and automates infrastructure monitoring, application performance monitoring (APM), and log management to provide unified, real-time observability of an organization’s entire technology stack. Founded in 2010, Datadog has rapidly become a go-to solution for cloud-scale monitoring, offering SaaS-based capabilities that enable businesses to improve agility, increase efficiency, and provide end-to-end visibility across dynamic, high-scale infrastructures.


Google BigQuery for Time Series Data

BigQuery can be used for storing and analyzing time series data, although it is more focused on traditional data warehouse use cases. BigQuery may struggle for use cases where low latency response times are required

Datadog for Time Series Data

Datadog excels in handling time series data through its metrics-based architecture. It is optimized for collecting and analyzing data points over time, such as CPU usage, memory consumption, or request latency. While Datadog is not a dedicated time series database, it integrates features like long-term data retention, aggregation, and visualization that make it well-suited for monitoring time-dependent metrics. However, it might not be the ideal choice for massive-scale, real-time analytics compared to specialized time series databases like InfluxDB.


Google BigQuery Key Concepts

Some important concepts related to Google BigQuery include:

  • Projects: A project in BigQuery represents a top-level container for resources such as datasets, tables, and views.
  • Datasets: A dataset is a container for tables, views, and other data resources in BigQuery.
  • Tables: Tables are the primary data storage structure in BigQuery and consist of rows and columns.
  • Schema: A schema defines the structure of a table, including column names, data types, and constraints.

Datadog Key Concepts

  • Datadog Agent: The Datadog Agent is a lightweight software installed on your servers, containers, or endpoints to collect and report metrics, logs, and traces. It acts as the primary bridge between your systems and the Datadog platform.
  • Dashboards: Dashboards in Datadog provide a customizable interface to visualize metrics, logs, and traces. They support various widgets, including time-series graphs, gauges, and heat maps, to present data in a meaningful way.
  • Integration : Datadog supports over 600 integrations to connect with various technologies, such as databases, cloud providers, and container orchestrators. Each integration collects relevant metrics, logs, and events and may require specific configuration via the Agent.
  • Events: Events are data that are streamed to Datadog via Agents, integrations, or custom applications. They are streamed to Datadog and can be used for filtering and correlating what is happening in your application
  • Tagging : Tags are metadata assigned to metrics, logs, and traces to group, filter, and search data. Effective use of tags, such as environment, region, or service, is crucial for organizing and analyzing data efficiently.


Google BigQuery Architecture

Google BigQuery’s architecture is built on top of Google’s distributed infrastructure and is designed for high performance and scalability. At its core, BigQuery uses a columnar storage format called Capacitor, which enables efficient data compression and fast query performance. Data is automatically partitioned and distributed across multiple storage nodes, providing high availability and fault tolerance. BigQuery’s serverless architecture automatically allocates resources for queries and data storage, eliminating the need for users to manage infrastructure or capacity planning.

Datadog Architecture

Datadog employs a SaaS (Software-as-a-Service) model with a highly distributed, cloud-based architecture. It uses agents to collect data from various sources, which are then processed and stored in Datadog’s cloud. The platform supports both structured and unstructured data, and its backend utilizes modern distributed systems principles to ensure scalability and reliability. Key components include the data ingestion pipeline, a metrics store, a logs processing system, and a query engine.

Google BigQuery Pricing Model

Google BigQuery pricing is based on a pay-as-you-go model, with costs determined by data storage, query, and streaming. There are two main components to BigQuery pricing:

  • Storage Pricing: Storage costs are based on the amount of data stored in BigQuery. Users are billed for both active and long-term storage, with long-term storage offered at a discounted rate for infrequently accessed data.
  • Query Pricing: Query costs are based on the amount of data processed during a query. Users can choose between on-demand pricing, where they pay for the data processed per query, or flat-rate pricing, which provides a fixed monthly cost for a certain amount of query capacity.

Datadog Pricing Model

Datadog uses a modular, usage-based pricing model where customers pay based on the specific products and volume of data they use. Pricing is typically divided among different products like Infrastructure Monitoring, APM, Logs, and more. Each product has its own pricing structure, often based on the number of hosts, instances, or data ingested. Datadog offers a Free tier with limited features and data caps, as well as Pro and Enterprise tiers that provide advanced features and higher limits.
