PipelineDB vs TimescaleDB: What are the differences?
Introduction
In the world of time-series data management, two popular options are PipelineDB and TimescaleDB. Both solutions offer different features and functionality, making them suitable for specific use cases. In this article, we will explore the key differences between PipelineDB and TimescaleDB to help you understand their unique offerings.
Data Processing Approach: PipelineDB is designed to process data in real-time, providing continuous analytics on streaming data. It allows for high-speed ingestion and queries, making it suitable for use cases that require immediate data analysis. On the other hand, TimescaleDB focuses on scalability and storage efficiency, offering greater flexibility for historical data analysis. It allows for storing and querying large amounts of time-series data efficiently.
Continuous Views vs. Hypertables: PipelineDB introduces the concept of continuous views, which are essentially continuously updated materialized views that provide efficient query capabilities on streaming data. Continuous views in PipelineDB can update as data flows into the system, allowing for real-time analytics. In contrast, TimescaleDB uses hypertables, an extension of PostgreSQL tables that efficiently store and manage time-series data. Hypertables in TimescaleDB can be partitioned and distributed, allowing for efficient data organization and query performance.
Data Storage Model: PipelineDB stores data primarily in memory, utilizing a combination of row and columnar storage formats for efficient data processing. This enables quick data ingestion and low-latency query performance. Conversely, TimescaleDB stores data on disk, leveraging a combination of traditional row-based and columnar storage techniques. This storage model optimizes data compression, allowing for efficient disk utilization and cost-effective storage of large amounts of time-series data.
Optimized for Different Workloads: PipelineDB is designed for use cases that require real-time analytics on streaming data, such as monitoring and IoT applications. It provides capabilities for continuous queries and aggregations, enabling immediate insights into data as it arrives. In contrast, TimescaleDB is optimized for historical data analysis and handling large-scale time-series workloads. Its focus on scalability and efficient storage makes it suitable for applications involving long-term data retention and complex analytics.
Open Source Ecosystem: Both PipelineDB and TimescaleDB are built on top of PostgreSQL, a powerful and extensible open-source database. However, PipelineDB is available as a separate project and requires installation and configuration alongside PostgreSQL. TimescaleDB, on the other hand, is available as an extension to PostgreSQL, making it easier to integrate into existing PostgreSQL deployments. This seamless integration allows users to leverage the vast PostgreSQL ecosystem, including tools, libraries, and community support.
Maturity and Community Support: TimescaleDB has been in development for several years and has gained a significant user base and community support. Its maturity is demonstrated by its inclusion as a recommended extension in the PostgreSQL ecosystem. PipelineDB, although a promising project, is relatively newer and may have a smaller community and ecosystem. Users considering these solutions should evaluate their requirements and consider the maturity and support available for their specific use case.
In Summary, PipelineDB and TimescaleDB differ in their data processing approach, storage model, and optimized workloads, making them suitable for specific use cases such as real-time analytics and historical data analysis, respectively. Both solutions leverage PostgreSQL, although TimescaleDB offers a more integrated experience as a PostgreSQL extension. Users should assess their requirements and consider factors like data ingestion speed, query latency, and community support when choosing between PipelineDB and TimescaleDB.
We are building an IOT service with heavy write throughput and fewer reads (we need downsampling records). We prefer to have good reliability when comes to data and prefer to have data retention based on policies.
So, we are looking for what is the best underlying DB for ingesting a lot of data and do queries easily
We had a similar challenge. We started with DynamoDB, Timescale, and even InfluxDB and Mongo - to eventually settle with PostgreSQL. Assuming the inbound data pipeline in queued (for example, Kinesis/Kafka -> S3 -> and some Lambda functions), PostgreSQL gave us a We had a similar challenge. We started with DynamoDB, Timescale and even InfluxDB and Mongo - to eventually settle with PostgreSQL. Assuming the inbound data pipeline in queued (for example, Kinesis/Kafka -> S3 -> and some Lambda functions), PostgreSQL gave us better performance by far.
Druid is amazing for this use case and is a cloud-native solution that can be deployed on any cloud infrastructure or on Kubernetes. - Easy to scale horizontally - Column Oriented Database - SQL to query data - Streaming and Batch Ingestion - Native search indexes It has feature to work as TimeSeriesDB, Datawarehouse, and has Time-optimized partitioning.
if you want to find a serverless solution with capability of a lot of storage and SQL kind of capability then google bigquery is the best solution for that.
I chose TimescaleDB because to be the backend system of our production monitoring system. We needed to be able to keep track of multiple high cardinality dimensions.
The drawbacks of this decision are our monitoring system is a bit more ad hoc than it used to (New Relic Insights)
We are combining this with Grafana for display and Telegraf for data collection
