             Summary: Planner: allow parsing directly a stream instead of a java.lang.String
                 Key: CALCITE-2662
                 URL: https://issues.apache.org/jira/browse/CALCITE-2662
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.17.0
            Reporter: Enrico Olivelli
            Assignee: Julian Hyde


In 1.17.0 the org.apache.calcite.tools.Planner interface only accept a java.lang.String as input.

In order to reduce memory allocations and copies it will be useful that the planner could accept the query in a more 'raw' format.

Creating a java.lang.String is very expensive, and if your "query" is coming from the network (think about a Netty Direct memory ByteBuf) you are forced to create a copy of the text of the query.
