--------------------------------------
Summary: Don't require use of JdbcSchema in
QuerySqlStatisticProvider
Key: CALCITE-3365
URL: https://issues.apache.org/jira/browse/CALCITE-3365
Project: Calcite
Issue Type: Improvement
Reporter: Lindsey Meyer
We're trying to pass in schema data manually to process queries for BigQuery,
but that causes problems in the QuerySqlStatisticProvider because it requires a
JdbcSchema in order to get the dialect and dataSource, as well as using a Jdbc
Builder.
I propose refactoring QuerySqlStatisticProvider to grab the dialect and
dataSource using unwrap on the schema instead, so that any schema that
implements unwrap methods for these types will work with
QuerySqlStatisticProvider. As well as using a generic RelBuilder, instead of a
JDBC_BUILDER.
