1. A database system, comprising: a first bounded buffer; a first buffer flush regulator to enforce a first load factor associated with the first bounded buffer by flushing objects from the first bounded buffer according to at least one of a first predetermined object lifetime threshold or first predetermined time interval; and a memory device having instructions stored thereon, the instructions including: a plurality of first instructions, each first instruction defining a respective consumer of a first set of consumers, wherein a first one of the consumers of the first set is to consume objects of a first type from the first bounded buffer; and a plurality of second instructions, each second instruction defining a task node for each consumer and assigning an executor selected from a group of executors including synchronous executor, time bounded executor, and asynchronous executor to a respective one of the consumers; wherein a task node corresponding to a second different one of the consumers of the first set is to generate objects of a second type that is different than the first type for consumption by a consumer of a second set that is different than the first set.
