how to add a new database dialect
the kylin I used is V2.4,but it does not support the use of the GBase database as a data source.I think it's because of the lack of GBase database dialects。so how to add this dialect?

Hi Alone,
I think that is easy to add a new type of JDBC data source. You can follow
such steps:
1) add the dialect in
source-hive/src/main/java/org/apache/kylin/source/jdbc/JdbcDialect.java
2) implement a new IJdbcMetadata if GBase's metadata fetching is different
with others and then register it in JdbcMetadataFactory
3) you may need to customize the SQL for creating/dropping table in
JdbcExplorer for GBase
Kaige, Shaoxiong, and other developers can comment if missing something. We
can further abstract the interface and make it as pluggable, I think this
task is in the plan. Please take a try and let us know if you see the
problem.
