From SQLAlchemy access Apache Kylin
$ python
>>> import sqlalchemy as sa
>>> kylin_engine = sa.create_engine('kylin://ADMIN:KYLIN@sandbox/learn_kylin?timeout=60&is_debug=1')
>>> results = kylin_engine.execute('SELECT count(*) FROM KYLIN_SALES')
>>> [e for e in results]
[(4953,)]
>>> kylin_engine.table_names()
[u'KYLIN_ACCOUNT',
u'KYLIN_CAL_DT',
u'KYLIN_CATEGORY_GROUPINGS',
u'KYLIN_COUNTRY',
u'KYLIN_SALES',
u'KYLIN_STREAMING_TABLE']
From Pandas access Apache Kylin
$ python
>>> import sqlalchemy as sa
>>> import pandas as pd
>>> kylin_engine = sa.create_engine('kylin://ADMIN:KYLIN@sandbox/learn_kylin?timeout=60&is_debug=1')
>>> sql = 'select * from kylin_sales limit 10'
>>> pd.read_sql(sql, kylin_engine)
From Superset access Apache Kylin
Now you can configure the DSN in your application to establish the connection with Apache Kylin.
For example, you may install Apache Kylin Python Client Library in your Superset environment and configure connection to Apache Kylin in Superset
then you may be able to query Apache Kylin one table at a time from Superset
you may also be able to query detail data
Alternatively, you may also be able to query multiple tables from Apache Kylin by using SQL Lab in Superset.
