Does Looker share PDTs between users?

Does Looker share PDTs between users?

• A. Yes, if they have the same definition
• B. No, they are user-specific
• C. Only in shared folders
• D. Only for administrators

Answer: (A)

Looker allows persistent derived tables (PDTs) to be shared among users when they have the same definition. This means that if multiple users are querying the same PDT that is defined in LookML, they can leverage the same underlying table and results, which improves efficiency and reduces redundant queries to the database. When users access a PDT with the same definition, they are effectively tapping into a shared resource, which can provide benefits such as faster reporting times and reduced load on the database. This sharing mechanism promotes collaboration and consistency across different users analyzing the same data. The other options suggest conditions under which PDTs might be shared or restricted, but they do not accurately capture Looker's functionality regarding PDT sharing based on definition. Specifically, PDTs are not user-specific in a strict sense, and sharing does not depend solely on folders or user roles like administrators; the critical aspect is the definition itself.
