  • Patent number: 11150806
    Abstract: Disclosed embodiments provide systems and methods for reducing disk storage and network latency. A method reducing disk storage and network latency comprises receiving customer data of a customer to store in a database, conditioning the customer data, and formatting the conditioned customer data into first and second data strings respectively having a first data type and a second data type. The method further comprises flipping a sign bit of the first data string, encoding the sign-bit-flipped first data string and second data string into serialized data by representing every two digits of the first string with one byte, and flipping all bits of the serialized data if the received customer data is represented by a negative value. The method further comprises storing the serialized data in the database if negative, receiving a request for the customer data, deserializing serialized data to be retrieved from the database, and retrieving the deserialized data from the database.
