Chunk Loop Start

When starting a loop with this node, each iteration processes a (consecutive) chunk of rows. The chunking can be set as either a fixed number of chunks or a fixed number of rows per chunk.

Options

Mode

Select if the chunking is based on a fixed number of rows per chunk or a fixed number of chunks.

Rows per chunk

Set the number of rows per chunk. The number of iterations is the row count of the input table divided by this value. To implement a streaming approach with one row at a time, set this value to 1.

Number of chunks

Set the number of chunks. The number of rows per chunk is the row count of the input table divided by this value.
