I’ve got a largge Quartz database that uses binary serialization across the board. I want to migrate everything in the JB to JSON serialization, and I’m using the example here as a guide.

I spin up quarts and configure the persistent job store to use the custom serializer. It loads all my blob_triggers and re-serializes them back into the database using JSON just fine, but even through it triggers the jobs, it doesn’t re-persist the jobdata column in JSON format.

In order to get Quartz to re-write the JobData to the database in the QUARTZ_JOB_DETAILS table, I have to change something in context.JobDetaul.JobDataMap. Here’s what I’m doing:

    [PersistJobDataAfterExecution]
    [DisallowConcurrentExecution]
    [Serializable]
    public class MigrationJob : IJob
    {
        public async Task Execute(IJobExecutionContext context)
        {
            var jobData = context.JobDetail.JobDataMap;
            var now = DateTimeOffset.Now;
            jobData["MigratedAt"] = now; // without this line, the data doesn't re-persist
            Console.WriteLine("{0} migrated at at {1}", context.JobDetail.Key.Name, now);
        }
    }

Is there a way to tell quartz to always persist job data rather than only when something about the JobDetails changes?
