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.

Also, we should describe existing updaters like BatchedReceiver, BatchedSorted.
