> Key: GEODE-8953
> URL: https://issues.apache.org/jira/browse/GEODE-8953
> Project: Geode
> Issue Type: Bug
> Components: docs
> Affects Versions: 1.13.1
> Reporter: Dave Barnes
> Assignee: Dave Barnes
> Priority: Major
> Labels: pull-request-available
>
> Community member @alberto.gomez requests that we re-introduce some verbiage
> that was deleted in the fix for "GEODE-5509: Rewrite the docs on transaction."
> The passage to re-instate is:
> "If other, non-transactional sources update the keys the transaction is
> modifying, the changes may intermingle with this transaction’s changes. The
> other sources can include distributions from remote members, loading
> activities, and other direct cache modification calls from the same member.
> When this happens, after your commit finishes, the cache state may not be
> what you expected."
> [~eshu]Â concurs, providing the background explanation:
> To achieve best performance, non-transactional operations do not acquire
> DLock used to check conflicts in a transaction. So transaction will not be
> able to detect the conflict caused by a non transactional operation. It is
> expected that user application always uses transaction or no transaction at
> all, unless user knows that certain regions or set of entries will not be
> modified by operations outside of a transaction.
