Abstract: A battery energy storage module and a battery energy storage device. The battery energy storage module comprises: a structure body (101), a support member (102), and a cell group (103). A cavity for accommodating the cell group (103) is formed inside the structure body (101). The structure body (101) is provided with an opening. The cell group (103) is disposed in the cavity of the structure body (101) through the opening of the structure body (101). The support member (102) is used for supporting the structure body (101) to protect the cell group (103) disposed in the cavity of the structure body (101). Because the support member (102) is used for supporting the structure body (101) to protect the cell group (103) disposed in the cavity of the structure body (101), the battery energy storage module can have strong impact resistance, and can be applied to a full vehicle environment alone without being disposed in a protection tray.

Abstract: A method for blockchain generation is provided. The method includes: sending, by a client, transaction information to a first node device, where the transaction information includes basic information and digest information; receiving, by the client, an endorsement result sent by the first node device, where the endorsement result includes a signature generated after the first node device successfully performs transaction simulation; and if the endorsement result meets a preset transaction condition, sending, by the client, the digest information and the endorsement result to a second node device, so that the second node device sends, to the first node device the digest information to generate a complete blockchain. In this way, only the digest information is transmitted between the first node device and the second node device. Therefore, the second node device does not obtain the complete transaction information, so that information security is improved.

Abstract: A consensus process recovery method and a related node, where the method includes determining, by a plurality of nodes, a target instance from one or more secondary instances, where a throughput of the target instance is higher than a throughput of a primary instance, and obtaining, by a first node and all second nodes, a consensus to replace the primary instance with the target instance as a new primary instance, where the second nodes are backup nodes running the target instance, and the first node is a primary node running the target instance.

Abstract: Methods and a system are provided. A method includes automatically detecting, by an attribute structural variation detector, attribute structural variations in record schemas of a database lacking schema enforcement. The automatically detecting step includes encoding, by an encoder, nodes in the record schemas based on respective updated node labels to obtain a plurality of codes. The encoding step comprises, for each of the plurality of codes: recording, by a label frequency counter, a frequency f1 of the record schemas that include a given label; and recording, by a label frequency counter, a frequency fc of the record schemas that use a given one of the plurality of codes to update a label of a next level. An attribute variation is detected and retrieved responsive to the frequency fc?0, and the frequency f1>(two times the frequency fc).

Abstract: A method and system for generating a job alert. According to embodiments of the present invention, before a target job is processed, a characteristic of input and output of the target job in at least one stage is determined through analyzing a historical job, and a resource overhead associated with the processing of the target job is calculated based on the characteristic of input and output. Then, an alert for the target job is generated in response to the resource overhead exceeding a predetermined threshold. In such manner, an alert for the target job can be proactively generated before the resource overhead problem occurs, so as to enable an administrator or developer to discover a fault in advance and adopt measures actively to avoid loss and damage to the intermediate results or output data when the target job is processed.
