Granule
From DocDataFlow
Granules are the 'chunks of data' that flow through the network of adapters defined by the personality.
They can represent any size of data: a granule could represent anything from a single bit to a complete database with all its content, or an even large clump of data.
When granules flow through a network of adapters they are often split into smaller granules by disassemblers, or smaller granules are collated into larger granules by assemblers.
