Summary: Add CacheKeyConfiguration to CacheConfiguration
Key: IGNITE-5458
URL: https://issues.apache.org/jira/browse/IGNITE-5458
Project: Ignite
Issue Type: Task
Components: cache
Reporter: Vladimir Ozerov
Assignee: Vladimir Ozerov
Fix For: 2.1
Currently affinity column of certain type is not known on startup, as types are
registered dynamically. For this reason affinity column could be resolved
incorrectly if needed before type is registered. E.g. this is the case for our
H2 tables, which need affinity key column on startup.
This could be resolved by setting {{IgniteConfiguration.cacheKeyConfiguration}}
property, which maps type name to affinity key column name. However, this
mechanism is not flexible enough because mappings cannot be changed in runtime.
We should add similar property to cache configuration and use it to resolve
affinity column. Ideally, affinity key should be removed from {{BinaryType}} at
all.
