URL: https://github.com/apache/paimon/pull/7000
<!-- Please specify the module before the PR name: [core] ... or [flink] ...
-->
### Purpose
truncatedString is similar to Spark's truncatedString, and its default value
also references Spark's default of 25.
```scala
def truncatedString[T](
seq: Seq[T],
start: String,
sep: String,
end: String,
maxFields: Int): String = {
if (seq.length > maxFields) {
if (truncationWarningPrinted.compareAndSet(false, true)) {
logWarning(
"Truncated the string representation of a plan since it was too
large. This " +
s"behavior can be adjusted by setting
'spark.sql.debug.maxToStringFields'.")
}
val numFields = math.max(0, maxFields - 1)
seq.take(numFields).mkString(
start, sep, sep + "... " + (seq.length - numFields) + " more fields"
+ end)
} else {
seq.mkString(start, sep, end)
}
}
```
