Dynamic Schema Configurations
-----------------------------
Key: HBASE-5335
URL: https://issues.apache.org/jira/browse/HBASE-5335
Project: HBase
Issue Type: New Feature
Reporter: Nicolas Spiegelberg
Assignee: Nicolas Spiegelberg
Currently, the ability for a core developer to add per-table & per-CF
configuration settings is very heavyweight. You need to add a reserved keyword
all the way up the stack & you have to support this variable long-term if
you're going to expose it explicitly to the user. This has ended up with using
Configuration.get() a lot because it is lightweight and you can tweak settings
while you're trying to understand system behavior [since there are many config
params that may never need to be tuned]. We need to add the ability to put &
read arbitrary KV settings in the HBase schema. Combined with online schema
change, this will allow us to safely iterate on configuration settings.
