Answer: Use a binary serialization format to reduce memory usage.
Using a binary serialization format can improve performance by reducing the amount of memory required to store data and reducing the CPU overhead associated with serialization and deserialization. This approach is particularly beneficial for large datasets, as it can significantly reduce the time taken to process data.
