Notes
In Salesforce, up to five batches can run concurrently per org. This means that if you have more than five batch jobs queued up for execution, some of them will be placed in a holding pattern until one of the running batch jobs completes and frees up a slot for a new batch to start.
It's important to note that this limit applies to all types of batch jobs, including Apex batch jobs, bulk API jobs, and other types of asynchronous processing. If you exceed this limit, you may receive an error message indicating that the system is unable to process your request.
To avoid hitting this limit, it's a good practice to design your batch jobs to run efficiently and complete as quickly as possible. You can also use tools such as asynchronous Apex Governor Limits Viewer in Salesforce to monitor the current state of batch jobs and their progress. By doing so, you can manage your batches more effectively and optimize their performance to meet your specific needs.
