![]() According to the project’s readme, the best practice is to “delegate high-volume, data-intensive tasks to an external service that specializes in that type of work”. Airflow is not built to move large quantities of data from one task/transformation to the next. There are plenty of instances when data versioning isn’t important for some projects. It is a good fit when there’s already a strong handle on data management for ML and tools in place for versioning, lineage, etc. Also workers/machines can be used to run tasks concurrently.īatch only, not recommended for streaming data sources.īatch and streaming data sources supported.ĬLI, GUI, gRPC, Python, Golang, and Javascript client.Īirflow works best with workflows that are mostly static and slowly changing (days and weeks and not hours or minutes). ![]() However, users can scale the number of workers to run multiple tasks concurrently.Įach task or transformation can be distributed or sharded across multiple workers/machines and then reassembled. Parallelization or distributed processingĮach task is managed by one worker/machine. Identifies what data was changed and only processes the diff. Incremental data processing (reduces processing time and costs) Data versions are stored in any cloud or on-prem object store.ĭata storage deduplication (reduces processing time, storage, and costs)ĭoes not capture any data lineage, metadata, or data versioning informationĭata lineage captured with complete versioning of data, pipeline and transformation code. Versions data, pipelines and provides data lineage natively. DAGs are versioned with a source code management system such as GitHub. Transformations or code runs inside Docker containers.ĭata-Driven Pipelines (triggers when data is changed or added)ĭAGs can be chained together but changing or adding data will not automatically trigger a pipeline run.Ĭan automatically trigger a pipeline run when data is added or changed.ĭata Versioning (used to reproduce a particular outcome) There’s no easy way to plug in different languages. Self-managed or hosted through Astronomer, Google, and AWS. Users can shard their data and elastically spin up workers to distribute the data processing of an individual task/transformation across multiple machines. Unlike many machine learning operations (ML Ops) solutions, Pachyderm supports structured and unstructured data. At its core, Pachyderm is data-centric with auto triggering of pipelines, data and pipeline versioning, data deduplication, parallelization, and incremental data processing. Pachyderm is a data pipelining and ML operations solution written in Go. Fundamentally a data pipeline tool, Airflow excels at scheduling and executing a series of tasks and their associated dependencies. Airflow then schedules and executes the workflow, which is composed of tasks, based on a time interval or event. Users define a workflow or directed acyclic graphs (DAGs) in Python scripts. It originated at Airbnb to help the company manage complex workflows. Data Pipelines: Airflow and PachydermĪpache Airflow is an open-source, batch-oriented data pipeline solution written in Python. Let’s examine the critical differences between both solutions and identify which use cases favor one over the other. Because of this, MLOps practitioners often find themselves comparing Airflow and Pachyderm. Both Pachyderm and Airflow are popular solutions in this category because they eliminate manual bottlenecks and accelerate time to data insights. As a data engineer, there are many tools to choose from that create and automate data pipelines.
