Where Master is responsible for the load of the write operation, which means that everything written is done on master, while the read operation is distributed on slave. This can greatly improve the efficiency of reading. In the general Internet application, after some data survey concluded that the ratio of read/write is about 10:1, that is, a large number of data manipulation is focused on the operation of Reading, which is why we have multiple slave reasons.Bu

selected as long as the leader is appended to the log and may not have been committed (acks=0 indicates that there is no need to wait for leader confirmation, Acks=1 indicates that a leader acknowledgment is required). In the former case, Acks=-1, the producer needs to wait a longer time. However, the confirmed messages are guaranteed to be retained in the broker. In the latter case, acks=0 or 1, the producer has lower latency and higher throughput, but some acknowledged messages may be lost in

The security of the cluster mainly considers the following aspects: Isolation of the container from the host; Limiting the ability of containers to adversely affect infrastructure and other containers; The principle of least privilege--to reasonably restrict the permissions of all components, to ensure that the component only performs its mandated behavior, limiting the scope of the permissions it can achieve by restricting the ability of

Python cluster algorithm-DBSACN instance analysis, pythondbsacn This example describes the Python clustering algorithm DBSACN. We will share this with you for your reference. The details are as follows: DBSCAN:It is a simple density-based clustering algorithm. In this implementation, DBSCAN uses the center-based method. In the center-based method, the density of each data point is measured by the number of

destination IP address, At present, it is mainly used in the cache cluster system, which differs from the LBLC algorithm in that it maintains a mapping from a target IP address to a set of servers, while the LBLC algorithm maintains a mapping from a destination IP address to a server. The algorithm finds the corresponding server group for the destination IP address according to the destination IP address of the request. Select a server from the serve
