What field configures the maximum number of persistent tables that can be built in parallel for the connection?

• A. Max PDT Connections
• B. Max PDT Builder Connections
• C. Max Cache Connections
• D. Max Derived Table Connections

Answer: (B)

The correct choice is centered on "Max PDT Builder Connections," which specifically addresses the configuration limit for the number of persistent derived tables (PDTs) that can be constructed simultaneously within a database connection. This setting is essential for optimizing the data processing capabilities of Looker. By controlling the number of parallel connections used for building PDTs, it helps balance load on the database while ensuring that data processing tasks are executed efficiently. Properly managing these connections is crucial in environments with considerable data volume or complex operations since it directly affects the performance and responsiveness of the Looker instance. In contrast, other options refer to different concepts. "Max PDT Connections" implies the total number of connections available for PDT operations but doesn’t specifically define the building process. "Max Cache Connections" pertains to the limits concerning cached queries and how often different cached responses can be accessed simultaneously. Lastly, "Max Derived Table Connections" refers to connections related to derived tables, which are distinct from persistent derived tables, thereby focusing on a different mechanism of data retrieval and storage in Looker's architecture. Understanding these differences is fundamental for effectively configuring and optimizing Looker's performance within a data environment.
