------------------------------------------
Summary: Synchronization of metadata and data
Key: IGNITE-16774
URL: https://issues.apache.org/jira/browse/IGNITE-16774
Project: Ignite
Issue Type: Improvement
Reporter: Vladislav Pyatkov
We have two type of data: metadata(table schema etc.) and user data. Metadata
should always actual through the whole cluster, otherwise we can get the data
which is not has a schema.
For reaching this purpose, the metadata is looking up from Metastorage each
time when we want to get it. It in not fast enough and does not match to
distributed system approach (we have a bottleneck into Metastorage).
This issue is a main for solving the problem of synchronization of Metadata
among cluster nodes. In ideal way the metadata will be getting locally without
a risk to change during of using it.
