Disclosed herein are system, method, and computer-readable device embodiments for mass insertion into single-threaded databases. An embodiment includes a processor and a memory, a storage layer to interface with a plurality of software applications and to receive data output from the plurality of software applications, and a listener that runs according to an update policy, to detect the presence of information newly stored within the storage layer. The processor and memory may be configured to maintain at least a part of a running database cluster including a plurality of nodes, with at least two nodes configured to run without multi-threading, and to execute an intermediate module to send at least part of the information to the database cluster, and to perform simultaneous access to multiple database nodes running without multi-threading.
