public static void maybeApplyExpirationDateOverflowPolicy(TableMetadata metadata,
                                                          int ttl,

computeLocalExpirationTime

public static int computeLocalExpirationTime(int nowInSec,
                                             int timeToLive)

This method computes the Cell.localDeletionTime(), maybe capping to the maximum representable value which is Cell.MAX_DELETION_TIME. Please note that the ExpirationDateOverflowHandling.ExpirationDateOverflowPolicy is applied during maybeApplyExpirationDateOverflowPolicy(org.apache.cassandra.schema.TableMetadata, int, boolean), so if the request was not denied it means its expiration date should be capped.
