In a distributed database, many nodes can store copies, or instances, of the same record. If the record is split on one node, it should be split on the other nodes to maintain consistency, concurrency, and correctness of the data in the distributed database. In some distributed databases, the records are locked during the update process to ensure data integrity. Unfortunately, locking the records can increase latency, especially for larger databases. But if the records aren't locked and a node fails as a record is being split and updated simultaneously, the split and update may not propagate throughout the distributed database, leading to a loss of data integrity. Exchanging messages about the status of record splitting and forwarding updates internally reduces the likelihood of a loss of data integrity due to a node failure.
US11573937B2 System and method for automatically resolving metadata structure discrepancies
A system includes first and second subsystems and a third processor. The first subsystem includes a first memory and a first processor. The first memory stores data, which includes metadata associated with transmitted metadata fields. The first processor transmits the data to the second subsystem. The second subsystem includes a second memory and a second processor. The second memory stores expected metadata fields. The second processor receives the data.

In response, the third processor prevents the second subsystem from executing an application configured to process the data using the expected metadata fields. The third processor resolves the mismatch by modifying the expected metadata fields such that they correspond to the transmitted metadata fields and allows the second subsystem to execute the application.

A preparation method of a zirconium-titanium-based alloy embedded aluminized layer includes putting a zirconium-titanium-based alloy and an aluminiferous penetrant into a mould from bottom to top in a sequence of a first penetrant layer, a first zirconium-titanium-based alloy, a second penetrant layer, a second zirconium-titanium-based alloy and a third penetrant layer, and compacting to obtain a mixed sample; sequentially covering a surface of a mixed sample with activated carbon powder and alkali metal halide, and then carrying out heating and cooling treatments to obtain a zirconium-titanium-based alloy embedded aluminized layer. The preparation method does not need to adopt a special heating furnace or carry out heat treatment under a vacuum condition in an actual application, which simplifies operation process and condition and is suitable for large-scale production and application due to few technical difficulties and low equipment investment cost.
US11572613B2 Method for manufacturing a metal sheet with a ZnAl coating and with optimized wiping, corresponding metal sheet, part and vehicle
A steel part includes a steel sheet substrate and a coating on at least one surface of the steel sheet substrate. The coating includes between 0.2 and 0.7% by weight of Al, with a remainder of the metal coating being Zn and inevitable impurities. The steel sheet substrate and the coating have at least one deformation. An outer surface of the coating has a waviness Wa0.8 of less than or equal to 0.43 μm.
