Description:
h2. Design
Optimize
org.apache.calcite.adapter.enumerable.EnumerableInterpretable#getBindable with
cache.
Cherry-pick from
[https://github.com/apache/calcite/pull/950|https://github.com/apache/calcite/pull/950,],
Calcite 1.19 uses Guava cache on Bindable instances.
Similar to {{calcite.bindable.cache.maxSize}} and
{{{}calcite.bindable.cache.concurrencyLevel{}}}, two KYLIN configs are added as
follows:
{code:java}
# Cache max size, default value is 10
kylin.query.calcite.bindable.cache.maxSize
# controll the concurrency level of cache, default value is 5
kylin.query.calcite.bindable.cache.concurrencyLevel{code}
