Nicolas Spiegelberg commented on HBASE-5335: -------------------------------------------- Note: alterations to the CF schema can be made online. Currently, alterations to the table-level schema requires a disable-modify-enable. This is related to online schema design but should be trivial to alter. > 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 > Labels: configuration, schema > Attachments: D2247.1.patch, D2247.2.patch, D2247.3.patch > > > 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. -- This message is automatically generated by JIRA.
