Vladimir Steshin updated IGNITE-17435: -------------------------------------- Description: 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 rebalance on that cache. * Avoid snapshotting. Also, the docs should note streamer's limitations and traits. was: 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.

Also, we should describe existing updaters like BatchedReceiver, BatchedSorted. > 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: Major > Labels: ise > > 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.
