摘要： A shared-nothing database system is provided in which the rows of each table are assigned to "slices", and multiple copies ("duplicas") of each slice are stored across the persistent storage of multiple nodes. Requests to read data from a particular row of the table may be handled by any node that stores a duplica of the slice to which the row is assigned. For each slice, a single duplica of the slice is designated as the "primary duplica". All DML operations are performed by the node that has the primary duplica of the slice to which the target row is assigned. The changes are then propagated other duplicas ("secondary duplicas") of the same slice.

摘要： A leader control plane node of a set of control plane nodes of a node cluster, may receive a request to store data in a distributed storage system including a set of access manager nodes. The leader control plane node may generate cache data identifying an instruction from the leader control plane node to one or more access manager nodes managed by the leader control plane node of the plurality of access manager nodes, the instruction instructing the one or more access manager nodes to store the data indicated in the request. The leader control plane node may then transmit a replication instruction to one or more follower control plane nodes of the plurality of control plane nodes to replicate the cache data in a respective cache of the one or more follower control plane nodes.

摘要： The present disclosure provides a data storage method, an apparatus, an electronic device and a storage medium. The data storage method includes: acquiring at least one piece of feature data to be stored in a target storage system, wherein each piece of the feature data comprises at least one sub-feature data, and each piece of the feature data has a corresponding primary key respectively; for each piece of the feature data, determining, from a plurality of first time partitions corresponding to the target storage system, a target time partition to which a data occurrence time of the feature data belongs, wherein each of the first time partitions corresponds to a corresponding number of buckets, each bucket is associated with one storage space of the target storage system; a total number of buckets corresponding to each of the first time partitions is determined by corresponding festival attribute information of the first time partition, or the total number of buckets corresponding to each of the first time partitions is determined by data storage capacity before the first time partition; and allocating, based on a total number of buckets corresponding to the target time partition and a primary key corresponding to the feature data, a corresponding bucket to the feature data, and storing the feature data in a storage space that is associated with the corresponding bucket of the feature data.
