Abstract: A processing device receives request from a process of a plurality of processes of a clusterized service, to attempt to create, in a file system accessible by the process, a file associated with a leader state of the plurality of processes. Responsive to successfully creating the file, the processing device to enable the process to enter the leader state. The processing device is further to enable the process to stay in the leader state for a lifetime of the process.

Abstract: A processing device receives request from a process of a plurality of processes of a clusterized service, to attempt to obtain exclusive access to a predetermined resource associated with a leader state of the plurality of processes. Responsive to successfully obtaining the exclusive access to the predetermined resource, the processing device enables the process to enter the leader state. The processing device enables the process to stay in the leader state for the lifetime of the process.

Abstract: A mixed checksum injection system includes a memory, at least one processor in communication with the memory, a data repository including content, and a server including a CRMS. The CRMS executes on the at least one processor to generate a plurality of checksum values for the content. The plurality of checksum values includes a first checksum value generated using a first checksum function and a second checksum value generated using a second checksum function. The CRMS receives a first request for the content for a first platform, and responsive to receiving the first request, renders first metadata. The CRMS injects the first checksum value and an identifier of the first checksum function into the first metadata. Then, the CRMS publishes the content and the associated first metadata including the injected first checksum value and the identifier of the first checksum function.
