Another great video but I'm curious when would I prefer to use this over a materialized view? The materialized columns seem just like a materialized view except you have more granular control of columns?
👍
How do you handle a sequential flat file with fixed length records and fixed length fields?
The audio is really rough :(
Would be interesting to list the use cases of this, is it just to get faster queries because querying the json isn’t as efficient ?
Nice! Was looking for this functionality a while ago. Keep the videos coming!
The audio on these are terrible.
Why I can't see the link you mentioned at the end of video :|
Because I foolishly forgot to include it. Here it is clickhouse.com/blog/working-with-time-series-data-and-functions-ClickHouse [Mark]
@@ClickHouseDB Thanks a lot!
Horrible ….
What language does he speak??
English. Apologies for the low quality audio.
Thank you so much for deep explanations. You have saved my days.. :)
CIDR /ˈsaɪdər, ˈsɪ-/
Great content :) Thank you very much
Have had similar experiences, it currently seems like more trouble than it's worth. One project that looks pretty interesting and just went open source is Dataherald.
Very cool! Can you set a custom domain to that? 😊
Not yet, but eventually!
And yes, time series is one of my main application for ClickHouse, so great if you keep this a priority use-case.
Good work!
fuck your english говори на русском блядь
How can we visualize the Map(String, String) type of data in superset?
Sorry for the probably stupid question, but if we just add skip index to town, will it help with the 1st case to speed up it? Can it be an alternative to projection or what is the significant difference between them? Thank you!
where I can download .jar file?
Hello! Do you have this presentation in PDF version? I'd like to take your queries and work with them.
Hey. At 23:30 on the video, there is a qrcode to access the slides. All the queries and code snippets are written in the comments of their respective slide. I previously tried to send you the link directly, but that reply is put under review. So you will need to scan the qrcode.
how we can connect looker studio to clickhouse
In order to archive data from that s3 bucket, I assume it's ok to move files out of that directory and it won't screw up the loading process for ClickHouse?
QUALIFY. Woo-hoo, liked it in Teradata
Does this protect from SQL injections?
Decent thanks guys
Very annoying and improper use of voice inflections.
how to do it on cloud managed service?
Will there be streams in russian?
What program is that on 3:00?
Can we create projections for distributed tables?
when you craft misleading title just to attract and bring in more audience you are causing more harm to yourself in our days.
dedublication can be achived zookeeper?
❤, блять, наконец то понятно кто то объяснил как кипер настроить
ch -q "select * from ''CMakeFiles.txt" ----- does it potentially expose attacking vulnerability?
I was looking all over for arrayJoin, didn't expect it to be named that! Thanks
Where we can find some more information about that magic variable "param_url"?
This is a way to define parameters in the CLI. You can do param_whateveryoulikehere and then it'll be available as 'whateveryoulikehere'
man this guy is everywhere! :)
I hope they destroyed that camera after recording this
Thanks for your job, guys!
I think you went too quickly through it. Some more description of the function signatures would have been useful.
Sad I missed this one but felt included with all the other Alans that joined!😅
Great job!
I'm currently storing 4 columns with the same data, in raw, flattened, compacted and distinct, with this knowledge I can reduce my storage by over 60% - nice one!!
