A system and method for of prioritizing accumulation of time-dependent data is disclosed. In an embodiment, a plurality of data elements are identified to be retrieved. The data elements include a high-priority data element and a low-priority data element. A first data retrieval operation is performed to retrieve the high-priority data element, to store a copy of the high-priority data element in a memory structure, and to reserve a memory space in the memory structure for the low-priority data element based on the low-priority data element corresponding to the high-priority data element. In parallel with the first data retrieval operation, a second data retrieval operation is performed to analyze the memory structure to detect the reserved memory space, upon detecting the reserved memory space, to retrieve the low-priority data element, and to store a copy of the low-priority data element in the reserved memory space.
