In the test suite, we use Hook.QUERY_PLAN to add handlers. You could do the same. The Elasticsearch adapter will call the handler with the query.
See https://github.com/apache/calcite/blob/4bc916619fd286b2c0cc4d5c653c96a68801d74e/core/src/main/java/org/apache/calcite/runtime/Hook.java#L95 <https://github.com/apache/calcite/blob/4bc916619fd286b2c0cc4d5c653c96a68801d74e/core/src/main/java/org/apache/calcite/runtime/Hook.java#L95> and code that references Hook.QUERY_PLAN.
