Embodiments of the present disclosure relate to a data storage method, a data read method, an electronic device, and a computer program product. The data storage method includes: acquiring identifiers of a predetermined number of trusted nodes, the predetermined number being associated with a secret sharing scheme to be used; generating a predetermined number of shared portion sets from input data by using the identifiers respectively as parameters of the secret sharing scheme; and respectively storing the predetermined number of shared portion sets in the predetermined number of trusted nodes according to a correspondence relationship between the predetermined number of shared portion sets and the predetermined number of trusted nodes. With the technical solution of the present disclosure, input data can be efficiently protected with trusted nodes by using a secret sharing scheme, and the confidentiality and integrity of the input data can be guaranteed.

Data storage method, data read method, electronic device, and program product

A microservice update system includes a build dispatcher system that receives a microservice modification request identifying first microservice(s) included in a plurality of microservices that provide a service. The build dispatcher system then triggers a respective microservice pipeline for each first microservice. A continuous integration system receives respective microservice modified code for each first microservice via the respective pipeline triggered for each, and update corresponding first portion(s) of service code. The continuous integration system then tests the updated service code in order to test the first microservice(s) that are provided by the first portion(s) of updated service code, and test second microservice(s) that are included in the plurality of microservices that provide the service, that are provided by at least one second portion of the updated service code that was not updated as part of the updating, and that are dependent on at least one of the first microservice(s).

Microservice update system

A message system includes a first node that may send a message to a second node, provide metadata associated with the message, and send the metadata to a database. The database may determine that the message was not received by the second node based upon the metadata and a current time, and direct the first node to resend the message to the second node in response to determining that the message was not received. The first node further may resend the message.

Apparatus and method for improving messaging system reliability

Embodiments of the present disclosure relate to a method, device and computer program product for storing data. The method comprises obtaining a first range of replica levels supported by a storage apparatus, wherein the replica level indicates the number of replicas of data. The method further comprises receiving a replica configuration requirement for an application, wherein the application supports a second range of replica levels. Moreover, the method further comprises determining a first replica level for the storage apparatus and a second replica level for the application based on the replica configuration requirement, the first range and the second range. By extracting the replica function supported by the storage apparatus, embodiments of the present disclosure can configure replica levels of the storage apparatus and the application from the global level for the user requirement for replicas of the data service.
