Update schema-appendix.adoc to fix wrong names

[quaff]

BATCH_EXECUTION_CONTEXT should be BATCH_JOB_EXECUTION_PARAMS
EXECUTION_ID should be JOB_EXECUTION_ID

Please check Frequency if it's up to date.

Is this related to https://jira.spring.io/browse/BATCH-2853?

[quaff]

@benas Yes.

[fmbenhassine]

ok thanks, I added a link to this PR in BATCH-2853.

BATCH_EXECUTION_CONTEXT should be BATCH_JOB_EXECUTION_PARAMS

This is actually not correct. BATCH_EXECUTION_CONTEXT has been replaced with BATCH_STEP_EXECUTION_CONTEXT and BATCH_JOB_EXECUTION_CONTEXT in d272105#diff-9df3d792ac9c1d09e598d04018ee1f6eL71-L80. And based on the frequency "On commit interval, a.k.a. chunk" mentioned in the appendix, it is definitely not BATCH_JOB_EXECUTION_PARAMS: this table is not queried/updated at each commit interval. It is BATCH_STEP_EXECUTION_CONTEXT that is updated at this frequency, here is an excerpt from the ExecutionContext section:

They are two different ExecutionContexts.
The one scoped to the Step is saved at every commit point in the Step,
whereas the one scoped to the Job is saved in between every Step execution.

@quaff Could you please update the PR accordingly?

@benas BATCH_STEP_EXECUTION_CONTEXT and BATCH_STEP_EXECUTION_CONTEXT are queried by primary key, so they should be excluded from this table.

[fmbenhassine]

Indeed, BATCH_STEP_EXECUTION_CONTEXT and BATCH_JOB_EXECUTION_CONTEXT are queried by primary keys (which are indexed by default), so this entry can be removed from the table. Thanks for the PR!
