Useful information about batch apex .....Thank you.

[@bhaskarshanigaram2599]

have a question like my query return 50millions records. And batch size is 2000 so execute method will be executed 25000 Times
1. As you said we have 100 jobs in flexi queue so that it will be failed right? As we have 25000 jobs and sales force try to move all these jobs to flexi queue.
Please exaplain how many records contains one flexi jobs?what if a query 50M records return and will we get flexi job limit exception error?if not how it will be procccesed all thses records in flexi queue?

[@sfdcpanther]

100 jobs means 100 batch job not 100 execute methods. There are also limits of having the total no of execution so you need to make sure that your query is not returning too many records which causes the limitations rather you can use 2 batch instead of one.

@@sfdcpanther Thanks for answer. Please just confirm that i have two batch apex classes ( having different object queries) which will be triggered from same transaction so that we have two flexi queue jobs i think.please confirm that.

[@sfdcpanther]

@@bhaskarshanigaram2599 Everybatch has it's own instance and transaction and yes there will be 2 entries

If want to learn vf pages and controller, I would suggest you to watch videos of Jeet sing.. Sfdc panther and jeet Singh videos are just awesome in explaining things.

what should we do if we need to process the record more than 50 million?

[@sfdcpanther]

50 million is a big numbers and Even the giant organization will not have that many records to process at a time. Still as a best practice we always need to filter the records based on certain criteria and after putting the criteria you are getting the 50M Records then you need to rethink about the criteria.
Otherwise to process bulk no of Records it's always recommended to use ETL Tool.

why cant we perform future methods in batch apex

[@vijaysinghnegi1991]

Please make a video for schedule Apex and Crone expression to run the batch Apex class after every 30 minutes.

[@sfdcpanther]

You can create a cron expression using cron maker website and then schedule the batch apex.
