An EntityBatchLoader using one or more SQL queries, which each initialize up to getSqlBatchSize() entities using a SQL IN predicate restriction - e.g., ... where id in (?,?,...).

The number of parameters rendered into the SQL is controlled by getSqlBatchSize(). Any unused parameter slots for a particular execution are set to null.
