I've got a process doing some calculations on a timer and sending updated table to another process. Its heap is more than 3x of used even after manual trigger of .Q.gc. key value used 567774096 heap 1946157056 peak 2617245696 I'm using KDB+ 4.0 2021....

I created a virtual query which clears some view states and set it as data source for an action. It works as expected when action is triggered but I found out that it is also executed at page load. If I pass parameters to the dashboard they are now c...

I'm trying to chart my data using R directly from q. The plot is opening up but the window is not responsive, can't be resized and it's marked as (Not Responding) by windows. I can close it by running dev.off() but it won't open up straight away the ...

My table has 54 columns of various simple types, mainly floats, symbols, ints and timestamps. Each column is of around 2Mb in size. I can reproduce it with your code by dropping n to 2000000, which makes columns similar in size to my case. .Q.gc[] do...

Thanks, I found one of the causes - code that brings and refreshes a large table from another process. I'm starting a fresh process and bringing in a table of 107Mb. The heap settles to 268Mb after .Q.gc[]. However after updating this table the heap ...

Thanks David, I got it working now. I was confused at first as there's no way to set a view state to a value in an action for a DataGrid, it can only copy from a cell. I adapted your solution and used the Row Id column instead of 'true', so in my cas...

How do I set triggerEnabled from an action (e.g. click on a cell in a data grid)? Isn’t that the same problem as setting the original view state to null?
