The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 21 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Paul Dix: Nobody will ever make the Lisp programming language popular
“Lisp, we're not going to do because Paul Graham and Rich Hickey couldn't make Lisp popular, and neither will we. Nobody will.”
Why traditional databases fail at time series workloads
“And actually no
Regular database is designed with this kind of workload in mind.
Databases, for the most part, assume that you want to keep your data around for a very long time.
So, these kind of unique aspects of time series make it kind of a degenerate case…”
Flux turns InfluxDB into a serverless execution platform for time series
“It essentially turns the database into a serverless execution platform for time series data. The idea is you can define any sort of custom logic that you want, inject it into the database, and it will periodically run that logic over the data that you're writi…”
Paul Dix: Telegraf is likely on tens to hundreds of millions of servers
“This project actually is our most popular open source project by far. We don't have any sort of tracking on it right now, but I would estimate that it's probably deployed on tens of millions of servers across the world, if not hundreds of millions at this poin…”
InfluxData is building PromQL support directly into Flux
“And we also are in the middle of building in support for PromQL, the Prometheus query language.”
DevOps metrics and IoT sensor data spaces look surprisingly similar
“And those, the sensor data and the DevOps data spaces, they look surprisingly similar. Because when you think about DevOps data, and you think about the metrics that you're collecting, the sensors are just software that you have on your servers. Whereas in sen…”
Building analytics apps in 2015 resembles web development in 1998
“Building an application with an analytics component today is like building a web application in 1998. You spend months and millions of dollars building infrastructure before you get to the actual thing you want to build that's driving user value, right?”
Dix: InfluxDB operates with zero external software dependencies
“It's an open source time series database with no external dependencies.”
No open-source projects focused on time-series databases in 2013
“So we looked at the open source time series space and found that nobody was really focused on it, and it seemed like A need that was emerging.”
Go's garbage collection makes InfluxDB unsuitable for sub-millisecond trading
“This isn't, this is written in Go, so, which is a garbage collected language, so worst case response time can be worse than what you would want in that kind of setup.”
An InfluxData customer deployed Telegraf to 45,000 servers in a single day
“Our, we've had customers, like, deploy it to 45,000 servers in a single day, so.”
HFT firms use InfluxDB and atomic clocks for sub-300ns drift
“There are high frequency trading firms that use it to track latencies in their network infrastructure, and they actually have, like, atomic clocks deployed in their data centers, so they guarantee less than 300 nanoseconds of clock drift Worldwide.”
InfluxDB 2.0 unifies the TICK stack into a single database
“So, my idea was within FluxDB two dot O, we could collapse these things into one cohesive whole, and have one language that ties all of it together.”
Flux combines a query optimizer, VM, and Turing-complete scripting language
“Flux is basically a new language that we're creating for two dot O. It's a combination of a bunch of things. It's basically a query planner, it's a query optimizer, but it's also a Turing complete scripting language, which includes a virtual machine, And a que…”
Dix: InfluxDB is targeting IoT consumer and industrial sensor data
“And then the last one that we're really targeting is sensor data. So this is IOT, both consumer and industrial, right? You're thinking power generation, oil and gas wells, and then on the consumer side, you know, fitness trackers to smart home stuff, all that …”
Dix: Ship code to where data lives, not data to code
“This is the key thing that we learned from Hadoop and Google's MapReduce framework, which is You want to ship the code to where the data lives, not the other way around.”
Dix: InfluxDB pairs a time series engine with an in-memory index
“So the InfluxDB is actually, it's kind of like two databases in one. So the time, there's the time series database, and that's useful for storing both regular and irregular time series. Regular is collected on fixed intervals, like once every 10 seconds. Irreg…”
Paul Dix: InfluxDB compresses measurement names and tags into eight-byte IDs
“When you send in a measurement name and a tag set, we compress all of that down into a single ID, a single eight-byte ID.”
Paul Dix: Regular time series data summarizes irregular event data
“The thing that's interesting about irregular time series data is that you can actually induce a regular time series from irregular time series data. Basically, a regular time series is just a summary of an irregular Series.”
