A technique for using a caching layer for key-value storage in a database is described. In one example of the present disclosure, a system can receive, at an unsorted data structure of a caching layer, a key-value pair associated with a data object. The unsorted data structure can store a first plurality of key-value pairs. The system can receive one or more operations for updating the key-value pair in the caching layer. The system can determine the key-value pair is to be migrated to a sorted memory table based on a caching algorithm. The system can migrate the key-value pair to a sorted memory table configured to store a second plurality of key-value pairs that is larger than the first plurality of key-value pairs and sort the key-value pair with the second plurality of key-value pairs prior to storing the key-value pair in the sorted memory table.

Power consumption can be reduced by selective memory chip hibernation. For example, a computing device can allocate first data associated with a first processing operation of a user device to a first chip of a dynamic random access memory (DRAM) of the user device. The computing device can allocate second data associated with a second processing operation of the user device to a second chip of the DRAM of the user device. The computing device can determine the first processing operation has been inactive for a predetermined period of time and migrate the first data from the first chip of the DRAM to a storage device of the user device. The computing device can hibernate the first chip of the DRAM while maintaining power to the second chip of the DRAM for continuing to perform the second processing operation.

A water filter having a housing having a water inlet and a water outlet on a first end, and a pair of replaceable carbon elements contained within the housing, each carbon element having a water inlet near an outside diameter and a water outlet near the center, both the water outlet and water inlet being on a first end of each carbon element and each of the carbon element inlets being in fluid communication with the housing water inlet and each of the carbon element outlets being in fluid communication with the housing water outlet.
