Nicholas Jiang updated FLINK-21045:
-----------------------------------
Description:
This improvement aims to
# Simplify the module discovery mapping by module name. This will encourage
users to create singleton of module instances.
# Support changing the resolution order of modules in a flexible manner. This
will introduce two methods {{#useModules}} and {{#listFullModules}} in both
{{ModuleManager}} and {{TableEnvironment}}.
# Support SQL syntax upon {{LOAD/UNLOAD MODULE}}, {{USE MODULES}}, and {{SHOW
[FULL] MODULES}} in both {{FlinkSqlParserImpl}} and {{SqlClient}}.
# Update the documentation to keep users informed of this improvement.

for more details.
was:
At present, Flink SQL doesn't support the 'load module' and 'unload module' SQL
syntax. It's necessary for uses in the situation that users load and unload
user-defined module through table api or sql client.
SQL syntax has been proposed in FLIP-68:
