/**
* The mutation manager enables different recipes or entity managers to use
* the same mutation for bulk operations. In addition a mutation manager
* can be used to implement write ahead semantics for 'atomic' mutations.
*
* The mutation manager is expected to be thread safe such that all mutations
* in the same thread go to the same mutation batch. This also means that
* getMutationBatch(), the mutations and the final commit() must occur within
* the same thread.
