com.datastax.driver.core |
The main package for the DataStax Java driver for Cassandra.
|
com.datastax.driver.core.policies |
Policies that allow to control some of the behavior of the DataStax Java driver for Cassandra.
|
Class and Description |
---|
AddressTranslater
Translates IP addresses received from Cassandra nodes into locally queriable
addresses.
|
LoadBalancingPolicy
The policy that decides which Cassandra hosts to contact for each new query.
|
Policies
Policies configured for a
Cluster instance. |
ReconnectionPolicy
Policy that decides how often the reconnection to a dead node is attempted.
|
RetryPolicy
A policy that defines a default behavior to adopt when a request fails.
|
SpeculativeExecutionPolicy
The policy that decides if the driver will send speculative queries to the next hosts when the current host takes too
long to respond.
|
Class and Description |
---|
AddressTranslater
Translates IP addresses received from Cassandra nodes into locally queriable
addresses.
|
ChainableLoadBalancingPolicy
A load balancing policy that wraps another policy.
|
CloseableAddressTranslater
Extends
AddressTranslater for implementations that need to free some resources
at Cluster shutdown. |
CloseableLoadBalancingPolicy
A load balancing policy that wants to be notified at cluster shutdown.
|
DCAwareRoundRobinPolicy
A data-center aware Round-robin load balancing policy.
|
DCAwareRoundRobinPolicy.Builder
Helper class to build the policy.
|
DefaultRetryPolicy
The default retry policy.
|
DowngradingConsistencyRetryPolicy
A retry policy that sometimes retries with a lower consistency level than
the one initially requested.
|
ExtendedRetryPolicy
A policy that defines a default behavior to adopt in the event of unexpected errors.
|
FallthroughRetryPolicy
A retry policy that never retries (nor ignores).
|
HostFilterPolicy
A load balancing policy wrapper that ensures that only hosts matching the predicate
will ever be returned.
|
LatencyAwarePolicy
A wrapper load balancing policy that adds latency awareness to a child policy.
|
LatencyAwarePolicy.Builder
Helper builder object to create a latency aware policy.
|
LatencyAwarePolicy.Snapshot
An immutable snapshot of the per-host scores (and stats in general)
maintained by
LatencyAwarePolicy to base its decision upon. |
LatencyAwarePolicy.Snapshot.Stats
A snapshot of the statistics on a given host kept by
LatencyAwarePolicy . |
LoadBalancingPolicy
The policy that decides which Cassandra hosts to contact for each new query.
|
NoSpeculativeExecutionPolicy
A
SpeculativeExecutionPolicy that never schedules speculative executions. |
Policies
Policies configured for a
Cluster instance. |
Policies.Builder
A builder to create a new
Policies object. |
ReconnectionPolicy
Policy that decides how often the reconnection to a dead node is attempted.
|
ReconnectionPolicy.ReconnectionSchedule
Schedules reconnection attempts to a node.
|
RetryPolicy
A policy that defines a default behavior to adopt when a request fails.
|
RetryPolicy.RetryDecision
A retry decision to adopt on a Cassandra exception (read/write timeout
or unavailable exception).
|
RetryPolicy.RetryDecision.Type
The types of retry decisions.
|
SpeculativeExecutionPolicy
The policy that decides if the driver will send speculative queries to the next hosts when the current host takes too
long to respond.
|
SpeculativeExecutionPolicy.SpeculativeExecutionPlan
A plan that governs speculative executions for a given query.
