> Fix Datastreamer documentation.
> -------------------------------
>
> Key: IGNITE-17435
> URL: https://issues.apache.org/jira/browse/IGNITE-17435
> Project: Ignite
> Issue Type: Sub-task
> Reporter: Vladimir Steshin
> Assignee: Vladimir Steshin
> Priority: Minor
> Labels: ise
> Fix For: 2.15
>
>
> The doc should mention something like:
> Setting the `allowOverwrite` property to false is best used for initial data
> load on a cluster with stable topology. When cluster works under load, some
> actions may cause issues with data consistency. To avoid them:
> * Avoid having the same keys repeating in the data being streamed;
> * Avoid concurrent updates of the cache that is being streamed into;
> * Avoid streamer fauilure.
> * Avoid snapshotting.
> Also, the docs should note streamer's limitations and traits.
> Additionally, we may warn into log that datastreamer should successfully
> finish.
