Abstract: A system for low latency caching of time-sensitive data is disclosed. The system comprises a database, one or more processors, and non-transitory memory. The non-transitory memory comprises instructions that cause the one or more processors to divide a table of the database into a plurality of logical partitions; during a first interval of time, insert new records exclusively into a first partition of the plurality of logical partitions; during a second interval of time, insert new records exclusively into a second partition of the plurality of logical partitions; during a subsequent interval of time, determine that a predetermined period of time has passed since conclusion of the first interval of time; and responsive to the determination that the predetermined period of time has passed, delete records from the first partition without changing contents of the second partition or any other partition of the plurality of logical partitions.

Abstract: A proton conductive film, a method of producing the proton conductive film, and a highly sensitive humidity sensor are provided. The proton conductivity (room temperature, 95% RH) of the proton conductive film is 3×10?21 Scm?1 or more, and the proton conductive film is usable under a neutral-solvent atmosphere. A highly proton conductive polymer film made of an organic/metallic hybrid polymer film including: one or more metal ions selected from a group consisting of Fe ion, Co ion, Ru ion, Zn ion, and Ni ion; and bis(terpyridyl)benzene, is used.
