Origload

Origload is a term used in data engineering and systems benchmarking to denote the act of loading the original, unmodified dataset into a system as a baseline operation in a pipeline. It focuses on measuring how quickly and efficiently data can be brought into a computing environment before any transformations take place.

Origin and usage of origload are informal, arising in discussions of data pipelines, ingestion architectures, and performance testing. It is not a formally standardized term, and its exact meaning can vary between organizations and contexts.

In practice, origload is used to benchmark ingestion readiness and to separate the costs of data movement from downstream processing. It helps analysts evaluate storage systems, network throughput, and memory or cache behavior independent of data transformation, indexing, or analytics.

What origload involves can include reading data from source storage, decompressing or deserializing as needed, and staging it in memory or on disk with minimal processing. The emphasis is on preservation of the original data as it exists in the source, serving as a baseline for comparison with transformed or enriched loads.

Common metrics associated with origload include load time, data transfer throughput, and peak memory use. Considerations include I/O bandwidth, storage latency, parallelism, and data format efficiency. Related concepts include full-load, initial-load, and ETL-style ingestion, though origload specifically targets the unaltered data entry phase.
