Check logical and physical plans


#1

Hello,

is there a way to check the logical / physical plan that is generated by SciDB for a query? I stumbled upon the expain_logical and explain_physical operators in a previous post, but it seems that the user does not have access to them. Is that correct?

Thank you,
Nantia

Hi Nantia, these operators are “hidden”, but you can use them by prefixing an underscore to their names. Beware though: these hidden, undocumented operators’ behavior may change from release to release, or they could be removed. Never build a production application using hidden operators, since you may find “the rug pulled out from under you” in the next release.

Best,
