Apache Cassandra
Apache Cassandra
Parameters:
Name
Type
Details
$version int
the actual protocol version, only 1 or 2 are supported
Returns:
Total number of IO threads to use for handling the requests.
Note: number of io threads * core connections per host <= total number of connections <= number of io threads * max connections per host
Parameters:
Name
Type
Details
$count int
total number of threads.
Returns:
Cassandra\Set $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.
