> Key: CALCITE-7504

> Project: Calcite
> Issue Type: Bug
> Components: core

> The Hypergraph-based join optimization uses logging statements that look like
> this:
> {code:java}
> LOGGER.debug("Initialize the dp table. Node {{}} is:\n {}",
> i,
> RelOptUtil.toString(hyperGraph.getInput(i)));{code}
> The problem is that these calls will evaluate their arguments, e.g.,
> toString, which can be quite expensive. Ideally a lazy version of logging
> should be used.
