Properties

connectionTimeoutMillis

var connectionTimeoutMillis: Long

How long to wait when establishing a TCP connection to a ScyllaDB node. Default is 5 000 ms.

heartbeatIntervalSeconds

var heartbeatIntervalSeconds: Int

localPoolSize

var localPoolSize: Int

Number of pooled connections held open to each node in the local datacenter. Wired to the driver's advanced.connection.pool.local.size (CONNECTION_POOL_LOCAL_SIZE) option (GH #80 / ISS-072); the driver's own default -- and this field's default -- is 1.

maxRequestsPerConnection

var maxRequestsPerConnection: Int

remotePoolSize

var remotePoolSize: Int

Number of pooled connections held open to each node in a remote datacenter. Wired to advanced.connection.pool.remote.size (CONNECTION_POOL_REMOTE_SIZE) option (GH #80 / ISS-072); default is 1, matching the driver's own default. Only relevant once cross-DC failover is actually enabled (loadBalancing.dcAwareFailover = true together with failover.onLocalDcUnavailable = FailoverPolicy.RETRY_REMOTE_DC) -- otherwise the driver never opens connections to remote-DC nodes at all and this value has no effect. Typically left at or below localPoolSize since sustained traffic to a remote DC should be the failover exception, not the steady state.

requestTimeoutMillis

var requestTimeoutMillis: Long

How long to wait for a CQL query response. Default is 5 000 ms (driver default is 2 000 ms).
