> In InMemoryColumnarTableScan, we make string of the statistics of all the columns and log them at INFO level whenever batch pruning happens. We get a performance hit in case there are a large number of batches and good number of columns and almost every batch gets pruned.
> We can make the string to evaluate lazily and change log level to DEBUG
