Is there a Spring Batch 3 Upgrade Script for MySQL?

问题

I haven't seen a script to do the DDL modification necessary to go from Spring Batch 2 -> 3 in MySQL. Curious if one exists?

回答1:

After running a quick comparison of the schemas, these appear to be the changes for upgrading from Spring Batch 2.2.7.RELEASE -> 3.0.1.RELEASE on MySQL.

ALTER TABLE `BATCH_JOB_EXECUTION` MODIFY COLUMN `EXIT_CODE` varchar(2500) DEFAULT NULL;
ALTER TABLE `BATCH_JOB_EXECUTION` ADD COLUMN `JOB_CONFIGURATION_LOCATION` varchar(2500) DEFAULT NULL;
ALTER TABLE `BATCH_JOB_EXECUTION_SEQ` ADD COLUMN `UNIQUE_KEY` char(1) NOT NULL;
ALTER TABLE `BATCH_JOB_EXECUTION_SEQ` ADD UNIQUE KEY `UNIQUE_KEY_UN` (`UNIQUE_KEY`);
ALTER TABLE `BATCH_JOB_SEQ` ADD COLUMN `UNIQUE_KEY` char(1) NOT NULL;
ALTER TABLE `BATCH_JOB_SEQ` ADD UNIQUE KEY `UNIQUE_KEY_UN` (`UNIQUE_KEY`);
ALTER TABLE `BATCH_STEP_EXECUTION` MODIFY COLUMN `EXIT_CODE` varchar(2500) DEFAULT NULL;
ALTER TABLE `BATCH_STEP_EXECUTION_SEQ` ADD COLUMN `UNIQUE_KEY` char(1) NOT NULL;
ALTER TABLE `BATCH_STEP_EXECUTION_SEQ` ADD UNIQUE KEY `UNIQUE_KEY_UN` (`UNIQUE_KEY`);

For anyone who wants to know the DDL changes for postgresql:

ALTER TABLE BATCH_JOB_EXECUTION ALTER COLUMN EXIT_CODE TYPE varchar(2500);
ALTER TABLE BATCH_JOB_EXECUTION ADD COLUMN JOB_CONFIGURATION_LOCATION varchar(2500) DEFAULT NULL;
ALTER TABLE BATCH_STEP_EXECUTION ALTER COLUMN EXIT_CODE TYPE varchar(2500);

This worked for me when I upgraded from 2.2.7.RELEASE -> 3.0.7.RELEASE.

Really surprised there's no migration guide/or scripts, at least that I could find.
