> Entirely implement resolution order as FLIP-68 concept
> ------------------------------------------------------
>
> Key: FLINK-15595
> URL: https://issues.apache.org/jira/browse/FLINK-15595
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Reporter: Jingsong Lee
> Priority: Minor
> Labels: auto-deprioritized-major, pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> First of all, the implementation is problematic. CoreModule returns
> BuiltinFunctionDefinition, which cannot be resolved in
> FunctionCatalogOperatorTable, so it will fall back to FlinkSqlOperatorTable.
> Second, the function defined by CoreModule is seriously incomplete. You can
> compare it with FunctionCatalogOperatorTable, a lot less. This leads to the
> fact that the priority of some functions is in CoreModule, and the priority
> of some functions is behind all modules. This is confusing, which is not what
> we want to define in FLIP-68.
> We should:
> * We should resolve BuiltinFunctionDefinition correctly in
> FunctionCatalogOperatorTable.
> * CoreModule should contains all functions in FlinkSqlOperatorTable, a
> simple way could provided calcite wrapper to wrap all functions.
> * PlannerContext.getBuiltinSqlOperatorTable should not contains
> FlinkSqlOperatorTable, we should use one
> FunctionCatalogOperatorTable.Otherwise, there will be a lot of confusion.
