(I'm taking bets that I can build this based on SQLite if I set my mind to it I learned a lot of creative database stunts at meetups and now from and I'm telling you folks a database is a framework to be used to build platforms not to just passively sit there in a corner hidden behind a cache databases aren't some mimimi :)

Great to see more people catching on to ClickHouseDB. We’re using ClickHouse at
@honeybadger to power our upcoming logging/observability tool (Honeybadger Insights).

We’re also benchmarking a replacement backend for . Looks like quite a performance gain so far!

Will hopefully have more to share soon, but in the meantime we discussed this on the latest episode of @FounderQuest. Give it a listen:

Building your own observability stack with and just got much easier. https://clickhouse.com/blog/clickhouse-grafana-plugin-4-0

Apparently, quickly becomes slower once you reach a dozen of million records and search through them. Even with indexes.
So I looked into . The same query on the same dataset only takes about 1/10 of the time. Impressive! 😯

Next week @cloudhiker will get a serious speed boost!

directly in the database!

With you can train a ML model (stochasticLinearRegression or stochasticLogisticRegression) and then use it to perform predictions!

The flow below also uses the s3 function to read the data from a bucket

Until a truly performant (= fast, low memory footprint) two dimensional storage ("table") type (*) emerges, what are the options for managing big data in ?

  1. DBI into a performant DBMS (/ column store/ )
  2. shell over #R's data.table or 's / data.table packages, use files to get data in and some form of IPC to get data out
  3. , others ?
    (*) this a list of things one could encapsulate as objects for

julioj,

@ChristosArgyrop @Perl Hey Christos, I’m partial to as you can see from my bio. In my security work I use it for network traffic metrics and observability. I mainly use JavaScript, Python, and Common Lisp to interact with ClickHouse. For R there’s https://github.com/IMSMWU/RClickHouse

Also, feel free to join our Slack where you can ask any and all questions from our community of users https://clickhousedb.slack.com

@julioj @Perl Thanks Julio. Looking at various 2D solutions to utilize and is definitely among those considered for a SQL form of solution (bonus there is a R interface - many analytics stuff are written in R).
Will take a look!

Hey people, do you have any good talks or articles to share on schema design for generic tagged metrics storage? Most discussion of schema design is around analytics of a specific type of data, but what if you're building, say, a metrics platform?

I learned A LOT about distributed databasing and querying from these three () webinars by altinity - if you're unfamiliar with the topic they are great intros, super motivating to learn more https://altinity.com/deep-dive-on-clickhouse-sharding-and-replication-webinar https://altinity.com/webinarspage/size-matters-best-practices-for-trillion-row-datasets-on-clickhouse https://altinity.com/webinarspage/all-about-zookeeper-and-clickhouse-keeper-too cc/ @janl great addition to the SQL stuff!!
