1. A system comprising: a processor; and a memory device communicatively coupled to the processor, the memory device storing instructions which when executed by the processor, cause the processor to: access input data comprising a unit of data processing resulting from a transaction request, the input data having a first data size; determine a memory associated with an object, the object including: a first section including one or more processed transactions, the one or more processed transactions having a second data size representing a quantity of data of the one or more processed transactions stored at the first section; and a second section including a value associated with the one or more processed transactions and having a third data size, the object having a fourth data size being a sum of the second data size and the third data size; in response to a sum of the first data size and the fourth data size being equal to or greater than a threshold amount: generate a historical transaction from the one or more processed transactions to result in a historical transaction data size equal to the second data size; store the historical transaction at a transaction datastore at one or more memory locations of the memory device, the transaction datastore having the second data size; remove the one or more processed transactions having the second data size from the first section of the object to reduce the fourth data size by the second data size; insert the input data into the first section of the object to increase the fourth data size by the first data size; and using the input data, update the value of the second section of the object; and in response to the sum of the first data size and the fourth data size being less than the threshold amount: insert the input data into the first section of the object to increase the second data size by the first data size; and using the input data, update the value of the second section of the object.
