Hello all,
I’ve tried quite a bit with what I thought would be a fairly simple task, but now I need your help:
Is there any way to get the dimensions of Opal DB tables from a R/DataSHIELD session, but BEFORE assiging the data to symbols in the R server session? The motivation behind this is the fact that “loading” the data from Opal to R server sessions via DSI::datashield.assign takes quite a bit of time when dealing with large datasets / tables. It would be nice to know the dimensions (especially row count) before this loading, so that a user can get an estimate of how long it takes or I as a developer can inform the user about that…
Thanks for any hints!
