  • Publication number: 20190236081
    Abstract: Technologies are described for performing synchronization within a database environment. A source host stores multiple database tables and a replica host stores copies of the multiple database tables. During synchronization, replication log replay is blocked at the replica node, and a multithreaded process locks the multiple database tables of the source hosts, reactivates replication log generation for each of the multiple database tables, and then unlocks the database tables. A synchronization timestamp is acquired and used to synchronize the multiple database tables with the copies of the multiple database tables. After synchronization, replication log replay is reactivated at the replica host for the copies of the multiple database tables.

  • Patent number: 10353114
    Abstract: A dual cap for protecting a humidity sensor of a radiosonde of an aerological observation system includes an outer cap and an inner cap. The dual cap surrounds the humidity sensor. The outer cap has an outer ventilation hole formed in its top, and an outer air circulation opening formed in its side periphery. The side periphery of the outer cap also has a first wall that acts as a barrier to air flow. The inner cap is affixed to and is disposed inside of the outer cap. A ceiling of the inner cap faces the outer ventilation hole so as to impose a barrier to air flow. The inner cap further has an inner ventilation hole in its top and an inner air circulation opening formed in its side periphery. The inner air circulation opening faces the first wall of the outer cap.

  • Publication number: 20190213203
    Abstract: Technologies are described for facilitating transaction processing within a database environment having a coordinator node, a first worker node, and at least a second worker node. The first worker node sends a request from to the coordinator node for at least a first synchronization token maintained by the coordinator node. The first worker node receives the at least a first synchronization token from the coordinator node. The first worker node assigns the at least a first synchronization token to a snapshot as a snapshot ID value. The snapshot is executed at the first worker node. The first worker node forwards the snapshot ID value to the at least a second worker node.
