Detailed Description

A pool of connections.

A pool of connections from a Geode client to a set of Geode servers.

Member Function Documentation

◆ Destroy() [1/2]

void Apache::Geode::Client::Pool::Destroy ( )

Destroys this pool closing any connections it produced.

Exceptions
IllegalStateExceptionif the pool is still in use

◆ Destroy() [2/2]

void Apache::Geode::Client::Pool::Destroy ( Boolean  keepAlive)

Destroys this pool closing any connections it produced.

Parameters
keepAlivewhether the server should keep the durable client's subscriptions alive for the timeout period
Exceptions
IllegalStateExceptionif the pool is still in use

◆ GetQueryService()

QueryService ^ Apache::Geode::Client::Pool::GetQueryService ( )

Returns the QueryService for this Pool.

The query operations performed using this QueryService will be executed on the servers that are associated with this pool. To perform Query operation on the local cache obtain the QueryService instance from the Cache.

Property Documentation

◆ Destroyed

Boolean Apache::Geode::Client::Pool::Destroyed
get

Indicates whether this Pool has been destroyed.

◆ FreeConnectionTimeout

TimeSpan Apache::Geode::Client::Pool::FreeConnectionTimeout
get

Returns the connection timeout of this pool.

◆ IdleTimeout

TimeSpan Apache::Geode::Client::Pool::IdleTimeout
get

Get the Idle connection timeout for this pool.

◆ LoadConditioningInterval

TimeSpan Apache::Geode::Client::Pool::LoadConditioningInterval
get

Returns the load conditioning interval of this pool.

◆ Locators

array< String^>^ Apache::Geode::Client::Pool::Locators
get

Returns an unmodifiable list of locators this pool is using.

Each locator is either one added explicitly when the pool was created or were discovered using the explicit locators.

If a pool has no locators then it can not discover servers or locators at runtime.

◆ MaxConnections

Int32 Apache::Geode::Client::Pool::MaxConnections
get

Get the maximum connections for this pool.

◆ MinConnections

Int32 Apache::Geode::Client::Pool::MinConnections
get

Get the minimum connections for this pool.

◆ MultiuserAuthentication

bool Apache::Geode::Client::Pool::MultiuserAuthentication
get

Returns

true

if multiuser authentication is enabled on this pool.

◆ Name

String^ Apache::Geode::Client::Pool::Name
get

Get the name of the pool

◆ PendingEventCount

Int32 Apache::Geode::Client::Pool::PendingEventCount
get


Returns the approximate number of pending subscription events maintained at server for this durable client pool at the time it (re)connected to the server.

Server would start dispatching these events to this durable client pool when it receives Cache#readyForEvents() from it.

Durable clients can call this method on reconnect to assess the amount of 'stale' data i.e. events accumulated at server while this client was away and, importantly, before calling Cache#readyForEvents().

Any number of invocations of this method during a single session will return the same value.

It may return a zero value if there are no events pending at server for this client pool. A negative value returned tells us that no queue was available at server for this client pool.

A value -1 indicates that this client pool reconnected to server after its 'durable-client-timeout' period elapsed and hence its subscription queue at server was removed, possibly causing data loss.

A value -2 indicates that this client pool connected to server for the first time.

Returns
int The number of subscription events maintained at server for this durable client pool at the time this pool (re)connected. A negative value indicates no queue was found for this client pool.
Exceptions
IllegalStateExceptionIf called by a non-durable client or if invoked any time after invocation of Cache#readyForEvents().

◆ PingInterval

TimeSpan Apache::Geode::Client::Pool::PingInterval
get

Get the ping interval for this pool.

◆ PRSingleHopEnabled

Boolean Apache::Geode::Client::Pool::PRSingleHopEnabled
get

Returns the true if a pr-single-hop is set to true on this pool.

◆ ReadTimeout

TimeSpan Apache::Geode::Client::Pool::ReadTimeout
get

Returns the read timeout of this pool.

◆ RetryAttempts

Int32 Apache::Geode::Client::Pool::RetryAttempts
get

Get the retry attempts for this pool.

◆ ServerGroup

String^ Apache::Geode::Client::Pool::ServerGroup
get

Returns the server group of this pool.

◆ Servers

array< String^>^ Apache::Geode::Client::Pool::Servers
get

Returns an unmodifiable list of servers this pool is using.

These servers were added explicitly when the pool was created.

◆ SniProxyHost

String^ Apache::Geode::Client::Pool::SniProxyHost
get

Get the host name for the pool's SniProxy.

◆ SniProxyPort

Int32 Apache::Geode::Client::Pool::SniProxyPort
get

Get the host port for the pool's SniProxy.

◆ SocketBufferSize

Int32 Apache::Geode::Client::Pool::SocketBufferSize
get

Returns the socket buffer size of this pool.

◆ StatisticInterval

TimeSpan Apache::Geode::Client::Pool::StatisticInterval
get

Get the statistic interval for this pool.

◆ SubscriptionAckInterval

TimeSpan Apache::Geode::Client::Pool::SubscriptionAckInterval
get

Returns the subscription ack interval of this pool.

◆ SubscriptionEnabled

Boolean Apache::Geode::Client::Pool::SubscriptionEnabled
get

Returns the true if a server-to-client subscriptions are enabled on this pool.

◆ SubscriptionMessageTrackingTimeout

TimeSpan Apache::Geode::Client::Pool::SubscriptionMessageTrackingTimeout
get

Returns the subscription message tracking timeout of this pool.

◆ SubscriptionRedundancy

Int32 Apache::Geode::Client::Pool::SubscriptionRedundancy
get

Returns the subscription redundancy level of this pool.

◆ ThreadLocalConnections

Boolean Apache::Geode::Client::Pool::ThreadLocalConnections
get

Returns the true if ThreadLocalConnections are enabled on this pool.

◆ UpdateLocatorListInterval

TimeSpan Apache::Geode::Client::Pool::UpdateLocatorListInterval
get

Get the update locator list interval for this pool.
