self
Cluster\Builder

withProtocolVersion

( int $version )

Force the driver to use a specific binary protocol version.

  • Apache Cassandra 1.2+ supports protocol version 1

self
Cluster\Builder

withIOThreads

( int $count )

Total number of IO threads to use for handling the requests.

Parameters:
Name Type Details
$count int

total number of threads.
Returns:
Type Details
Cluster\Builder

self
Cluster\Builder

withConnectionsPerHost

( int $core = 1, int $max = 2 )

Cassandra\Set the size of connection pools used by the driver. Pools are fixed when only $core is given, when a $max is specified as well, additional connections will be created automatically based on current load until the maximum number of connection has been reached. When request load goes down, extra connections are automatically cleaned up until only the core number of connections is left.

Parameters:
Name Type Details
$core int

minimum connections to keep open to any given host
$max int

maximum connections to keep open to any given host
Returns:
Type Details
Cluster\Builder

self
Cluster\Builder

withReconnectInterval

( float $interval )

Specify interval in seconds that the driver should wait before attempting to re-establish a closed connection.

Parameters:
Name Type Details
$interval float

interval in seconds
Returns:
Type Details
Cluster\Builder

self
Cluster\Builder

withLatencyAwareRouting

( bool $enabled = true )

Enables/disables latency-aware routing.

Parameters:
Name Type Details
$enabled bool

whether to actually enable or disable the routing.
Returns:
Type Details
Cluster\Builder

self
Cluster\Builder

withTCPNodelay

( bool $enabled = true )

Disables nagle algorithm for lower latency.

Parameters:
Name Type Details
$enabled bool

whether to actually enable or disable nodelay.
Returns:
Type Details
Cluster\Builder

self
Cluster\Builder

withTCPKeepalive

( float $delay )

Enables/disables TCP keepalive.

Parameters:
Name Type Details
$delay float

the period of inactivity in seconds, after which the keepalive probe should be sent over the connection. If set to null, disables keepalive probing.
Returns:
Type Details
Cluster\Builder

self
Cluster\Builder

withTimestampGenerator

( Cassandra\TimestampGenerator $generator )

Sets the timestamp generator.

Parameters:
Name Type Details
$generator Cassandra\TimestampGenerator

A timestamp generator that will be used to generate timestamps for statements.
Returns:
Type Details
Cluster\Builder

self
Cluster\Builder

withSchemaMetadata

( bool $enable = true )

Enables/disables Cassandra\Schema Metadata.

If disabled this allows the driver to skip over retrieving and updating schema metadata, but it also disables the usage of token-aware routing and $session->schema() will always return an empty object. This can be useful for reducing the startup overhead of short-lived sessions.

Parameters:
Name Type Details
$enable bool

whether the driver fetches and maintains schema metadata.
Returns:
Type Details
Cluster\Builder
