Compute delta sets from warehouse high-water marks or snapshots so each run processes only new or changed records. Use this skill whenever the user mentions incremental load, high water mark, delta detection, watermark, merge upsert, changed records, snapshot diff, or is working with dbt, Snowflake, Spark, even if they never say "incremental loading logic" explicitly. Routes live lookups through the Incremental-Load-Plugin endpoint. Do not use it for unrelated application feature work or general coding questions.
