Summary: Provide distributed metastorage interface
Key: IGNITE-13800
URL:
https://issues.apache.org/jira/browse/IGNITE-13800 Project: Ignite
Issue Type: New Feature
Reporter: Alexey Goncharuk
We need to crystallize the metastorage interface prototype from the IEP to understand how it will be integrated with other system components.
Need to cover:
* Asynchrony aspects
* Possible error codes (connection failure -> unknown result vs Raft failure -> known result, etc)
* Complex multi-updates (aka transactions)
* Watchers. Each node can watch all updates and filter locally or adjust the watched ranges dynamically (consistency is important here)
These interfaces are considered "client" interfaces as they will be available on all nodes in the cluster
