-----------------------------------------------
Summary: Move namespace to RS group can support multiple options
to move tables under it
Key: HBASE-28406
URL: https://issues.apache.org/jira/browse/HBASE-28406
Project: HBase
Issue Type: Improvement
Components: rsgroup
Reporter: Rajeshbabu Chintaguntla
Assignee: Rajeshbabu Chintaguntla
Fix For: 4.0.0-alpha-1, 3.0.0-beta-2
As discussed here
[https://github.com/apache/hbase/pull/5661#issuecomment-1949090826]
Move namespaces to rsgroup can have multiple options like:
# *Move All Tables:* This option involves moving all tables within a namespace
to the new RS group, regardless of the current RS group they belong to. This
would effectively consolidate all tables of the namespace into the new RS
group. This is the same as the current implementation so it can be default
behavior.
# {*}Move Tables present in current RS group{*}: With this option, only tables
belonging to the current RS group of the namespace would be moved to the new RS
group. This provides more granular control, allowing users to choose specific
tables to move based on their needs. If the namespace does not belong to any RS
group, the namespace tables in the default RS group would be moved to the new
RS group.
# *Move No Tables:* This option involves changing the RS group of the
namespace without moving any tables. Existing tables would remain in their
current RS group. This could be useful if there's a desire to separate the
namespaces by RS group but without immediately moving the tables.
With this options we can give control to user choose proper option based on the
requirements.
