[Dragonliu2018]

I hereby agree to the terms of the CLA available at: https://docs.databend.com/dev/policies/cla/

Summary

support map lambda functions

• map_filter
• map_transform_keys
• map_transform_values
• json_map_filter
• json_map_transform_keys
• json_map_transform_values

for example:

MySQL [(none)]> select map_transform_keys({1:2,3:4}, (k, v) -> k + 1);
+------------------------------------------------+
| map_transform_keys({1:2,3:4}, (k, v) -> k + 1) |
+------------------------------------------------+
| {2:2,4:4}                                      |
+------------------------------------------------+
1 row in set (0.046 sec)

MySQL [(none)]> select map_transform_values({'a':'b','c':'d'}, (k, v) -> concat(k, v));
+-----------------------------------------------------------------+
| map_transform_values({'a':'b','c':'d'}, (k, v) -> concat(k, v)) |
+-----------------------------------------------------------------+
| {'a':'ab','c':'cd'}                                             |
+-----------------------------------------------------------------+
1 row in set (0.047 sec)

MySQL [(none)]> select map_filter({1:2,3:4}, (k, v) -> k = 1);
+----------------------------------------+
| map_filter({1:2,3:4}, (k, v) -> k = 1) |
+----------------------------------------+
| {1:2}                                  |
+----------------------------------------+
1 row in set (0.051 sec)

MySQL [(none)]> select json_map_transform_keys('{"data":"bend","time":"space"}'::variant, (k, v) -> concat(k, v));
+--------------------------------------------------------------------------------------------+
| json_map_transform_keys('{"data":"bend","time":"space"}'::VARIANT, (k, v) -> concat(k, v)) |
+--------------------------------------------------------------------------------------------+
| {"databend":"bend","timespace":"space"}                                                    |
+--------------------------------------------------------------------------------------------+
1 row in set (0.052 sec)

MySQL [(none)]> select json_map_transform_values('{"data":"bend","time":"space"}'::variant, (k, v) -> concat(k, v));
+----------------------------------------------------------------------------------------------+
| json_map_transform_values('{"data":"bend","time":"space"}'::VARIANT, (k, v) -> concat(k, v)) |
+----------------------------------------------------------------------------------------------+
| {"data":"databend","time":"timespace"}                                                       |
+----------------------------------------------------------------------------------------------+
1 row in set (0.044 sec)

MySQL [(none)]> select json_map_filter('{"data":"bend","time":"space"}'::variant, (k, v) -> k = 'data');
+----------------------------------------------------------------------------------+
| json_map_filter('{"data":"bend","time":"space"}'::VARIANT, (k, v) -> k = 'data') |
+----------------------------------------------------------------------------------+
| {"data":"bend"}                                                                  |
