1. A method comprising:
under control of one or more computing systems configured with specific executable instructions, receiving a request from a processing entity for readings for first and second service point channels; generating a processing tree for the first service point channel and a processing tree for the second service point channel, the processing tree for the first service point channel and the processing tree for the second service point channel each including multiple levels of nodes; retrieving, from a data store that stores configuration data and readings from multiple service point channels, configuration data for at least one node of a first level of the processing tree for the first service point channel and configuration data for at least one node of a first level of the processing tree for the second service point channel with a first single request to the data store, the configuration data associated with the first service point channel indicating that the first service point channel is associated with a formula for calculating at least one reading for the first service point channel; retrieving, from the data store, configuration data for at least one node of a second level of the processing tree for the first service point channel and configuration data for at least one node of a second level of the processing tree for the second service point channel with a second single request to the data store; upon generating the processing tree for the first service point channel and the processing tree for the second service point channel, retrieving, from the data store, the at least one reading that is associated with the first service point channel and at least one reading that is associated with the second service point channel; and providing the retrieved readings to the processing entity. |
