Which option describes a common use of the Split-Merge Block?

• A. To enhance performance through parallelism
• B. To merge all output features together into one
• C. To reduce the number of output features from a workspace
• D. To merge workspaces and other actions before a final action

Answer: (C)

Split-Merge blocks are used to shape the feature flow by sending the incoming features into parallel paths for processing and then recombining the results. The key effect of this recombination is often to reduce the total number of output features from the workspace. By processing on separate branches and then merging, you can consolidate results, deduplicate, or summarize, producing a smaller, more manageable set of features for downstream writers. While splitting can enable parallel work, the common value of this block is in how it ends up limiting the number of features emitted. It isn’t about merging all outputs into one across the entire run, nor is it about merging workspaces themselves.
