Record Class JobLease

java.lang.Object
java.lang.Record
com.kingsrook.qqq.backend.core.jobs.model.JobLease
Record Components:
chunkId - the leased chunk
jobId - its job
seq - the chunk's sequence in the job
attempt - the attempt number this lease runs (1 = first)
podId - the pod holding the lease
token - the fencing token
expiresAt - when the lease ends without a heartbeat (database clock)
public record JobLease(Integer chunkId, Integer jobId, Integer seq, Integer attempt, String podId, String token, Instant expiresAt) extends Record
A worker's lease on one chunk. Every chunk write (progress, checkpoint, completion) is fenced by the token: a writer whose lease was reclaimed fails.
