    Abstract: An accelerator intermediary node (AIN) associated with a data store obtains an indication of a control setting to be applied with respect to a write request directed to a data item, where the control setting specifies a target for one or more of replication count, data durability, a transaction grouping with respect to a write request, or back-end synchronization node. Using the control setting, a write propagation node set is identified for the write request. The write propagation node set includes another accelerator intermediary node and/or a storage node of a data store. Respective operation requests corresponding to the write request are transmitted to one or more members of the write propagation node set. A write coordinator role may be verified prior to attempting a commit together of a plurality of write requests as part of a multi-write transaction.
