Yury Gerzhedovich updated IGNITE-18156:
---------------------------------------
Description:
We need to provide an ability to configure distribution zones by DDL commands.
Let's extend SQL grammar with following syntax:
{code:java}
CREATE ZONE
{ fq_zone_name | simple_zone_name }
[WITH
[
<data_nodes_auto_adjust> |
DATA_NODES_FILTER = filter |
(<data_nodes_auto_adjust>, DATA_NODES_FILTER = filter)
],
[PARTITIONS = partitions],
[REPLICAS = replicas],
[AFFINITY_FUNCTION = function]
]
[;]
<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}
{code:java}
DROP ZONE {fq_zone_name | simple_zone_name}{code}
As a result the parser should be able to parse mentioned statements and provide
a valid AST representing those statements.
