> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Yury Gerzhedovich
> Priority: Major
> Labels: ignite-3
>
> 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.
