cache population

Hi,

1.
i have a cached view to an in memory source,
when i make a change in the schema (add a new field)
to the view in automatically populates the data.

is this normal? because i have 3M rows and when ever that
occur the server get stuck until the end of the population...

2.
does the in memory delete all data in the cache when it populates data ?
- (when i am not using increment)

3. is there a way to control the "in memory" db?
how many rows there are?
how much memory it uses?
if the populate went ok?
a scale of time remain to end of population?

i also consider to add a create/update option to the in memory

lets say i work with an SAP ERP and a row that exist on the
in memory had changed/update - the row as a key .
in this case i cant use the increment option and thats not optimal
that because it way better to bring only those rows that added or changed
in the last X days . and not all the 3-4 Milion records every night
that way we can even keep the reports almost "live"

thank you

We have managed to reproduce this issue.
We have logged this as a bug and still investigating the exact cause.
I will let you know when we have a fix for this.
(please make sure you are subscribed to this post, as I will mention the fix here)

Yes, all data is deleted and re-populated.

No, unfortunately you can't configure these the columnar database.
You can however modify how much memory Yellowfin uses.
Please see this post on how to do this:

i also consider to add a create/update option to the in memory
Unfortunately, if you don't use increments, this is not possible.
I will discuss this with the development team to see if this is something we can implement in a future build.

I hope this answers your questions for now.

I will get back to you regarding the bug.
