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 AWS Timestream and DataBend so you can quickly see how they compare against each other.
The primary purpose of this article is to compare how AWS Timestream and DataBend 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.

Additionally, Timestream supports SQL-like querying and integrates with popular analytics tools, making it easy for users to gain insights from their time series data.
DataBend for Time Series Data
DataBend’s architecture and processing capabilities make it a suitable choice for working with time series data. Its support for both batch and streaming data processing allows users to ingest, store, and analyze time series data at scale. Additionally, DataBend’s integration with Apache Arrow and its powerful query execution framework enable efficient querying and analytics on time series data, making it a versatile choice for applications that require real-time insights and analytics.
AWS Timestream Key Concepts
- Memory Store: In AWS Timestream, the Memory Store is a component that stores recent, mutable time series data in memory for fast querying and analysis.
- Magnetic Store: The Magnetic Store in AWS Timestream is responsible for storing historical, immutable time series data on disk for cost-efficient, long-term storage.
- Time-to-Live (TTL): AWS Timestream allows users to set a TTL on their time series data, which determines how long data is retained in the Memory Store before being moved to the Magnetic Store or deleted.
DataBend Key Concepts
- DataFusion: DataFusion is a core component of DataBend, providing an extensible query execution framework that supports both SQL and DataFrame-based query APIs.
- Ballista: Ballista is a distributed compute platform within DataBend, built on top of DataFusion, that allows for efficient and scalable execution of large-scale data processing tasks.
- Arrow: DataBend leverages Apache Arrow, an in-memory columnar data format, to enable efficient data exchange between components and optimize query performance.
AWS Timestream Architecture
Timestream is built on a serverless, distributed architecture that supports SQL-like querying capabilities. Its data model is specifically tailored for time series data, using time-stamped records and a flexible schema that can accommodate varying data granularities and dimensions. The core components of Timestream’s architecture include the Memory Store and the Magnetic Store, which together manage data retention, storage, and querying. The Memory Store is optimized for fast querying of recent data, while the Magnetic Store provides cost-efficient, long-term storage for historical data.
DataBend is built on a cloud-native, distributed architecture that supports both NoSQL and SQL-like querying capabilities. Its modular design allows users to choose and combine components based on their specific use case and requirements. The core components of DataBend’s architecture include DataFusion, Ballista, and the storage layer. DataFusion is responsible for query execution and optimization, while Ballista enables distributed computing for large-scale data processing tasks. The storage layer in DataBend can be configured to work with various storage backends, such as object storage or distributed file systems.
