> Hello everyone
> At present, there are codes that depend on hive in many places of the parsed
> functions and tables. The functions and tables of hive in individual dialects
> need to be parsed according to the part of flink, so try the analysis method
> based on flink SPI, which is compatible with kafka's DDL DML
>
> I observe the community’s proposal
> Flip-152:
> [https://cwiki.apache.org/confluence/display/FLINK/FLIP-152%3A+Hive+Query+Syntax+Compatibility]
> We can know that
> ```
> CREATE CATALOG myhive WITH (
> 'Type' ='hive',
> 'Default-database' ='default',
> 'Hive-conf-dir' ='/data/hive/conf/'
> );
> To
> USE CATALOG myhive;
> Set table.sql-dialect=hive;
> ```
> When specifying the sql-dialect type, it will follow the SPI from the
> configuration file
> The org.apache.flink.table.factories.TableFactory file under
> flink-connector-hive is assigned to HiveParserFactory to parse the
> corresponding grammar, and HiveParser is the corresponding grammar parser
> And perform grammatical analysis in HiveParserFactory#create
> During the course of investigating kafka-eagle, I found
> Among them, KSQL is also based on calcite for grammatical analysis, and can
> support DDL and DML of kafka tables
> Test-related classes are in: KSqlParser#TestKSqlParser
> And completed the analysis of the corresponding grammar in
> KsqlParser#parseQueryKSql
> Does the community have any good suggestions for this proposal?
