Thanks David

I have to understand how to  make it active on background every 300 milliseconds.

my inquiry is more for integrating python udf as a call-back / event handler to timer tick.

Actually I have to connect a consistent data source to kdb+ , using python. I have

python programs to get data from data sources but don’t know how to:

1. use an event handler to accept the data and push it to a kdb+ refinery data base.

2. setup multiple sources to update the same data base and write it to HDB at end of day.

 

do you know how to do it?

Thanks

I can’t get it working the output is not clear and I can’t understand

whet is the problem?

Hi Laura

I modified the table to csv format, yet I get very strange results when uploading.

(In private…. I can’t share the data)

can you ask one of your support team to contact me? I need support to understand

how to do it.

 

Thanks

Hi Laura

Thanks but it did not help me.

I have an excel file xslx with data (multiple tables) I couldn’t upload it to my workspace.

what is the fastest way to get it done?

thanks

Ori

Thanks Laura

I search for an answer without a repository. Is there a project without any repository option?

I need the developer only on my local computer and don’t want to waste time on git handling…

Thanks

Ori

I installed vcpkg arrow on the following folder

my kdb+ bin folder is C:workKXdbkdbw64
my vcpkg folder is C:workKXdbvcpkginstallvcpkginstalledx64-windowsbin
in order that arrowkdb.dll library can load copy all the dlls to kdbw64

hi rocuinneagain

Thanks for the link.  it gave me a hint about using the q script to init connection.

I try to do something totally different. my goal is to create “software” type solace instance

on my local machine (windows 10 x64).  I installed docker instance of solace.

how can I find the connection parameters described on the white paper (Messaging), see attached screenshot – the UI when I surf to my docker software solace page.

[kovacsi]

Thanks Leah

I asked the same questions on Solace community and got instructions to use

it on a separate instance ( Docker or virtual or cloud ).

I will install docker desktop and attempt to deploy solace pubsub+ broker.

Do you know if from architectural point of view it is possible to operate

when host computer has the Kdb installation and deployment , and only

the broker is on virtual / container instance? or should I install Kdb+ as well

on docker container?

 

Thanks

Ori
