[jira] [Updated] (IGNITE-18254) Sql. Extend SQL grammar with ALTER ZONE statement
[ https://issues.apache.org/jira/browse/IGNITE-18254?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yury Gerzhedovich updated IGNITE-18254:
---------------------------------------
Description:
As we can CREATE and DROP ZONE need to provide ability to altering a distribution zones by DDL commands.
Let's extend SQL grammar with following syntax:
{code:java}
ALTER ZONE
{ fq_zone_name | simple_zone_name }
WITH
[<data_nodes_auto_adjust>],
[DATA_NODES_FILTER = filter],
[REPLICAS = replicas],
[;]
<data_nodes_auto_adjust> ::= [
DATA_NODES_AUTO_ADJUST_SCALE_UP = scale_up_value |
DATA_NODES_AUTO_ADJUST_SCALE_DOWN = scale_down_value |
(DATA_NODES_AUTO_ADJUST_SCALE_UP = scale_up_value & DATA_NODES_AUTO_ADJUST_SCALE_DOWN = scale_down_value) | DATA_NODES_AUTO_ADJUST = auto_adjust_value
]{code}
So, could be changed any distributed zone parameters except PARTITIONS and AFFINITY_FUNCTION
