Show HN: Interactive map for architecting big data pipelines

This is very useful.

I wish it had some information about supported languages. Most of the processing systems are JVM-based and require that you write your program in a JVM language. Some have Python support. But I have yet to encounter one that allows you write your pipelines in Go, Rust or JavaScript, for example. One notable exception is Storm, which supports pluggable runners, including one that talks to an external program over standard I/O. My impression that aside from Python, today's pipelines require a large amount of JVM buy-in, something I'm personally not interested in.

I'd also love some kind of metric for "aliveness". For example, my impression is that Storm was hot for about a week, and then Spark and Flink happened, and now nobody is talking about it, and Twitter itself has apparently replaced it with Heron.

Storm is very much alive. Many of its users are simply running it reliably in production now. At my company, we are well past our trillionth production tuple running through Storm.

Also note that unlike Spark, Storm is a pure open source project that does not have a major commercial entity marketing its use cases. Hortonworks has put a little marketing effort behind it, but otherwise, it's just a mature & active Apache infrastructure project. Storm 2.0 is coming out soon and features a slew of performance- and reliability-improving enhancements.

But as for marketing buzz, Google has commercial reasons for you to use Beam and Dataflow, for example. And likewise Databricks for Spark.

It's probably a good idea to pick production large-scale data infrastructure on a metric other than recency of marketing buzz.

Thanks, that's helpful. Is building a pipeline with Java, consisting entirely of shell spouts, a viable option? Are there downsides to not using the Java API?

I agree, though the storm IRC channel is a bit of a ghost town the google group is fairly active.

If you're looking for something that doesn't constrain you to a particular language take a look at Pachyderm. It's built around containers so you can run any code you want. I designed it with JVM-phobes like you (and me) in mind.

Cool, thanks! I haven't looked closely at it, but the "version controlled" part is something I don't need/want. Does it get in the way at all? I'm mostly looking for incremental, semi-real-time streaming processing, not something where you shoot off a big job on a dataset and get back results.

jdoliner 8 years ago | | |

The version control semantics of the system are pretty crucial for some of the features you describe wanting. Pachyderm supports incremental operations on stream-like datasets. But what's going on under the hood is that the dataset is being version controlled and thus the system can tell which data has changed and only process the new data. Hope that helps, I'd be happy to chat more about your specific use case. Shoot me an email at jdoliner@pachyderm.io

You can also use Spark's pipe to call external programs.

lobster_johnson 8 years ago | | |

Ergonomically speaking, how practical is that? Do you get all the benefits and performance of an equivalent Java pipeline?

swah 8 years ago | |

Do you see any reason Golang would be less suited for those tasks?

Wow, this is awesome. What a simple yet useful idea.

This format lends itself to data processing, but I think it would be really nice to apply it a variety of workflows. For example, you could model the software deployment process across different languages and frameworks. It could be a good complement to StackShare.

A bit of constructive feedback: I'm not a stickler for UX or design, but maybe spruce up the gray boxes a bit. I've never been a designer though, so take that for what you will.

If you're aiming to be comprehensive, then you may want to add Onyx under streaming processors. It's not as popular as the options you've listed though, so I understand why it might be left off.

Thanks, we've included it in the Unified Batch processing because of its ability to have large window sizes that enable batch processing.

This is awesome. Great aggregating of so many buzzwords and brand names that I've heard over the years. Nice job!

Keep it simple and hierarchical. I suggest additional filters for each component of the data engineering flow that can discern unique features or commonalities.

ddrum001 8 years ago | |

Thanks, we tried to keep it simple and streamlined. If you know of any features or common patterns that would be helpful, let us know.

Interesting that Microsoft's only showing in this map is for Azure Blob Storage.

theatraine 8 years ago | |

Batch processing: Azure Data Lake(https://azure.microsoft.com/en-us/solutions/data-lake/)

Stream processing: Azure Stream Analytics (https://azure.microsoft.com/en-us/services/stream-analytics/)

SQL server is mentioned, but Azure Cosmos DB should also be mentioned (https://azure.microsoft.com/en-us/services/cosmos-db/)

ddrum001 8 years ago | | |

Fair point - the set of technologies is based off the teams we work closest with, which admittedly have a bias towards open source and Linux. So far, our map is far from comprehensive, so appreciate the suggestions (exactly what we're looking for by show HN).

To that point, just added CosmosDB, and plan to add others soon.

greggyb 8 years ago | | |

Email me if you want to talk architectural patterns or Microsoft products or both.

Details are in my profile.

SQL DW / APS

Analysis Services

Event Hub

IoT Hub

And hosting for a lot of the open source items in the original post.

It seems more a survey of tools the author knows or likes.

jnatkins 8 years ago |

StreamSets Data Collector is another useful open-source ingest tool. I'm biased, but people seem to like it.

Strange that Apache Flink and Google Dataflow don't figure in the Stream Processing list

ddrum001 8 years ago | |

We put Dataflow and Flink in the "Unified Processing" since they can handle batch and streaming (as opposed to tools that only handle steaming).

We might add them explicitly to Streaming as well though.

rahilb 8 years ago |

Storm also has a Scala api, but is filtered when selecting Stream Processing and Scala.

Aegeaner 8 years ago |

Why is there no Flink in Streaming processing framework?

drfloob 8 years ago | |

Flink is listed under `Unified Processing` as it supports both batch and streaming (Kappa Architecture)

What do you think of Arctic for the Data point ?

rjbwork 8 years ago |

Kind of cool, but only 2 entries from Azure that aren't on other places.

Kind of useless for us on Azure.

Citus DB is missing.
