readAndUpdateRequestsWithLatestProcessTime

public static com.google.common.collect.ImmutableList<DnsRefreshRequest> readAndUpdateRequestsWithLatestProcessTime(String tld,
 org.joda.time.Duration cooldown,
 int batchSize)

Returns pending DNS update requests that need further processing up to batch size, in ascending order of their request time, and updates their processing time to now.

The criteria to pick the requests to include are:

• They are for the given TLD.
• Their request time is not in the future.
• The last time they were processed is before the cooldown period.

deleteRequests

public static void deleteRequests(Collection<DnsRefreshRequest> requests)

Removes the requests that have been processed.

Note that if a request entity has already been deleted, the method still succeeds without error because all we care about is that it no longer exists after the method runs.

getDnsAPlusAAAATtlForHost

public static long getDnsAPlusAAAATtlForHost(String host,
 org.joda.time.Duration dnsDefaultATtl)
