Method Details

build

public DnsServiceEndpointGroup build()

Returns a newly created DnsServiceEndpointGroup.

eventLoop

public DnsServiceEndpointGroupBuilder eventLoop(EventLoop eventLoop)

Sets the EventLoop to use for sending DNS queries.

ttl

public DnsServiceEndpointGroupBuilder ttl(int minTtl,
 int maxTtl)

Sets the minimum and maximum TTL of the DNS records (in seconds). If the TTL of the DNS record returned by the DNS server is less than the minimum TTL or greater than the maximum TTL, the TTL from the DNS server will be ignored and minTtl or maxTtl will be used respectively. The default minTtl and maxTtl are 1 and Integer.MAX_VALUE, which practically tells to respect the server TTL.

queryTimeout

public DnsServiceEndpointGroupBuilder queryTimeout(Duration queryTimeout)

Sets the timeout of the DNS query performed by this endpoint group. 0 disables the timeout.

DnsNameResolverBuilder.queryTimeoutMillis(long)

queryTimeoutMillis

public DnsServiceEndpointGroupBuilder queryTimeoutMillis(long queryTimeoutMillis)

Sets the timeout of the DNS query performed by this endpoint group in milliseconds. 0 disables the timeout.

See Also:

DnsNameResolverBuilder.queryTimeoutMillis(long)

serverAddresses

public DnsServiceEndpointGroupBuilder serverAddresses(InetSocketAddress... serverAddresses)

Sets the DNS server addresses to send queries to. Operating system default is used by default.

serverAddresses

public DnsServiceEndpointGroupBuilder serverAddresses(Iterable<InetSocketAddress> serverAddresses)

Sets the DNS server addresses to send queries to. Operating system default is used by default.

backoff

public DnsServiceEndpointGroupBuilder backoff(Backoff backoff)

Sets the Backoff that determines how much delay should be inserted between queries when a DNS server sent an error response. Backoff.exponential(1000, 32000).withJitter(0.2) is used by default.

selectionStrategy

public DnsServiceEndpointGroupBuilder selectionStrategy(EndpointSelectionStrategy selectionStrategy)

Sets the EndpointSelectionStrategy that determines the enumeration order of Endpoints.
