(upbeat music) >> Okay, we're back. I'm Dave Vellante with The Cube and you're watching Evolving InfluxDB into the smart data platform made possible by influx data. Anais Dotis-Georgiou is here. She's a developer advocate for influx data and we're going to dig into the rationale and value contribution behind several open source technologies that InfluxDB is leveraging to increase the granularity of time series analysis and bring the world of data into realtime analytics. Anais welcome to the program. Thanks for coming on. >> Hi, thank you so much. It's a pleasure to be here. >> Oh, you're very welcome. Okay, so IOx is being touted as this next gen open source core for InfluxDB. And my understanding is that it leverages in memory, of course for speed. It's a kilometer store, so it gives you compression efficiency it's going to give you faster query speeds, it's going to see you store files and object storages so you got very cost effective approach. Are these the salient points on the platform? I know there are probably dozens of other features but what are the high level value points that people should understand? >> Sure, that's a great question. So some of the main requirements that IOx is trying to achieve and some of the most impressive ones to me the first one is that it aims to have no limits on cardinality and also allow you to write any kind of event data that you want whether that's lift tag or a field. It also wants to deliver the best in class performance on analytics queries. In addition to our already well served metric queries we also want to have operator control over memory usage. So you should be able to define how much memory is used for buffering caching and query processing. Some other really important parts is the ability to have bulk data export and import, super useful. Also, broader ecosystem compatibility where possible we aim to use and embrace emerging standards in the data analytics ecosystem and have compatibility with things like SQL, Python and maybe even Pandas in the future. >> Okay, so a lot there. Now we talked to Brian about how you're using Rust and which is not a new programming language and of course we had some drama around Rust during the pandemic with the Mozilla layoffs but the formation of the Rust Foundation really addressed any of those concerns and you got big guns like Amazon and Google and Microsoft throwing their collective weights behind it. It's really adoption is really starting to get steep on the S-curve. So lots of platforms, lots of adoption with Rust but why Rust as an alternative to say C++ for example? >> Sure, that's a great question. So Rust was chosen because of his exceptional performance and reliability. So while Rust is syntactically similar to C++ and it has similar performance it also compiles to a native code like C++ But unlike C++ it also has much better memory safety. So memory safety is protection against bugs or security vulnerabilities that lead to excessive memory usage or memory leaks. And Rust achieves this memory safety due to its like innovative type system. Additionally, it doesn't allow for dangling pointers and dangling pointers are the main classes of errors that lead to exploitable security vulnerabilities in languages like C++. So Rust like helps meet that requirement of having no limits on cardinality, for example, because it's we're also using the Rust implementation of Apache Arrow and this control over memory and also Rust's packaging system called Crates IO offers everything that you need out of the box to have features like async and await to fix race conditions to protect against buffering overflows and to ensure thread safe async caching structures as well. So essentially it's just like has all the control all the fine grain control, you need to take advantage of memory and all your resources as well as possible so that you can handle those really, really high cardinality use cases. >> Yeah, and the more I learn about the new engine and the platform IOx et cetera, you see things like the old days not even to even today you do a lot of garbage collection in these systems and there's an inverse, impact relative to performance. So it looks like you're really, the community is modernizing the platform but I want to talk about Apache Arrow for a moment. It's designed to address the constraints that are associated with analyzing large data sets. We know that, but please explain why, what is Arrow and what does it bring to InfluxDB? >> Sure. Yeah. So Arrow is a a framework for defining in memory column data. And so much of the efficiency and performance of IOx comes from taking advantage of column data structures. And I will, if you don't mind, take a moment to kind of illustrate why column data structures are so valuable. Let's pretend that we are gathering field data about the temperature in our room and also maybe the temperature of our store. And in our table we have those two temperature values as well as maybe a measurement value, timestamp value maybe some other tag values that describe what room and what house, et cetera we're getting this data from. And so you can picture this table where we have like two rows with the two temperature values for both our room and the store. Well, usually our room temperature is regulated so those values don't change very often. So when you have calm oriented storage essentially you take each row each column and group it together. And so if that's the case and you're just taking temperature values from the room and a lot of those temperature values are the same then you'll, you might be able to imagine how equal values will then enable each other and when they neighbor each other in the storage format this provides a really perfect opportunity for cheap compression. And then this cheap compression enables high cardinality use cases. It also enables for faster scan rates. So if you want to define like the min and max value of the temperature in the room across a thousand different points you only have to get those a thousand different points in order to answer that question and you have those immediately available to you. But let's contrast this with a row oriented storage solution instead so that we can understand better the benefits of column oriented storage. So if you had a row oriented storage, you'd first have to look at every field like the temperature in the room and the temperature of the store. You'd have to go across every tag value that maybe describes where the room is located or what model the store is. And every timestamp you then have to pluck out that one temperature value that you want at that one time stamp and do that for every single row. So you're scanning across a ton more data and that's why row oriented doesn't provide the same efficiency as column and Apache Arrow is in memory column data column data fit framework. So that's where a lot of the advantages come from. >> Okay. So you've basically described like a traditional database a row approach, but I've seen like a lot of traditional databases say, okay, now we've got we can handle Column format versus what you're talking about is really kind of native is it not as effective as the former not as effective because it's largely a bolt on? Can you like elucidate on that front? >> Yeah, it's not as effective because you have more expensive compression and because you can't scan across the values as quickly. And so those are, that's pretty much the main reasons why row oriented storage isn't as efficient as column oriented storage. >> Yeah. Got it. So let's talk about Arrow data fusion. What is data fusion? I know it's written in Rust but what does it bring to to the table here? >> Sure. So it's an extensible query execution framework and it uses Arrow as its in memory format. So the way that it helps InfluxDB IOx is that okay it's great if you can write unlimited amount of cardinality into InfluxDB, but if you don't have a query engine that can successfully query that data then I don't know how much value it is for you. So data fusion helps enable the query process and transformation of that data. It also has a Pandas API so that you could take advantage of Pandas data frames as well and all of the machine learning tools associated with Pandas. >> Okay. You're also leveraging Par-K in the platform course. We heard a lot about Par-K in the middle of the last decade cuz as a storage format to improve on Hadoop column stores. What are you doing with Par-K and why is it important? >> Sure. So Par-K is the column oriented durable file format. So it's important because it'll enable bulk import and bulk export. It has compatibility with Python and Pandas so it supports a broader ecosystem. Par-K files also take very little disc space and they're faster to scan because again they're column oriented, in particular I think Par-K files are like 16 times cheaper than CSV files, just as kind of a point of reference. And so that's essentially a lot of the benefits of Par-K. >> Got it. Very popular. So and these, what exactly is Influx data focusing on as a committer to these projects? What is your focus? What's the value that you're bringing to the community? >> Sure. So InfluxDB first has contributed a lot of different things to the Apache ecosystem. For example, they contribute an implementation of Apache Arrow and go and that will support clearing Influx. Also, there has been a quite a few contributions to data fusion for things like memory optimization and supportive additional SQL features like support for timestamp, arithmetic and support for exist clauses and support for memory control. So yeah, Influx has contributed a lot to the Apache ecosystem and continues to do so. And I think kind of the idea here is that if you can improve these upstream projects and then the long term strategy here is that the more you contribute and build those up then the more you will perpetuate that cycle of improvement and the more we will invest in our own project as well. So it's just that kind of symbiotic relationship and appreciation of the open source community. >> Yeah. Got it. You got that virtuous cycle going people call it the flywheel. Give us your last thoughts and kind of summarize, what the big takeaways are from your perspective. >> So I think the big takeaway is that, Influx data is doing a lot of really exciting things with InfluxDB IOx and I really encourage if you are interested in learning more about the technologies that Influx is leveraging to produce IOx the challenges associated with it and all of the hard work questions and I just want to learn more then I would encourage you to go to the monthly Tech talks and community office hours and they are on every second Wednesday of the month at 8:30 AM Pacific time. There's also a community forums and a community Slack channel. Look for the InfluxDB underscore IOx channel specifically to learn more about how to join those office hours and those monthly tech talks as well as ask any questions they have about IOx what to expect and what you'd like to learn more about. I as a developer advocate, I want to answer your questions. So if there's a particular technology or stack that you want to dive deeper into and want more explanation about how InfluxDB leverages it to build IOx, I will be really excited to produce content on that topic for you. >> Yeah, that's awesome. You guys have a really rich community collaborate with your peers, solve problems and you guys super responsive, so really appreciate that. All right, thank you so much Anais for explaining all this open source stuff to the audience and why it's important to the future of data. >> Thank you. I really appreciate it. >> All right, you're very welcome. Okay, stay right there and in a moment I'll be back with Tim Yoakam. He's the director of engineering for Influx Data and we're going to talk about how you update a SaaS engine while the plane is flying at 30,000 feet. You don't want to miss this. (upbeat music)
