Serialized Fields

controllerURI

java.net.URI controllerURI

controllerURI The controller rpc URI. This can be of 2 types 1. tcp://ip1:port1,ip2:port2,... This is used if the controller endpoints are static and can be directly accessed. 2. pravega://ip1:port1,ip2:port2,... This is used to autodiscovery the controller endpoints from an initial controller list.

credentials

io.pravega.shared.security.auth.Credentials credentials

Credentials to be passed on to the Pravega controller for authentication and authorization.

deriveTlsEnabledFromControllerURI

boolean deriveTlsEnabledFromControllerURI

An internal property that determines whether TLS enabled is derived from Controller URI. It cannot be set directly by the caller. It is interpreted as: false - if ClientConfig.enableTlsToController and/or ClientConfig.enableTlsToSegmentStore is/are set, and if either of them is set to false. true - if neither ClientConfig.enableTlsToController or ClientConfig.enableTlsToSegmentStore are set, or if both are set to true.

enableTlsToController

boolean enableTlsToController

An optional property representing whether to enable TLS for client's communication with the Controller. If this property and ClientConfig.enableTlsToSegmentStore are not set, and the scheme used in ClientConfig.controllerURI is tls or pravegas, TLS is automatically enabled for both client-to-Controller and client-to-Segment Store communications.

enableTlsToSegmentStore

boolean enableTlsToSegmentStore

An optional property representing whether to enable TLS for client's communication with the Controller. If this property and ClientConfig.enableTlsToController are not set, and the scheme used in ClientConfig.controllerURI is tls or pravegas, TLS is automatically enabled for both client-to-Controller and client-to-Segment Store communications.

maxConnectionsPerSegmentStore

int maxConnectionsPerSegmentStore

Maximum number of connections per Segment store to be used by connection pooling.

metricListener

io.pravega.shared.metrics.MetricListener metricListener

An optional listener which can be used to get performance metrics from the client. The user can implement this interface to obtain performance metrics of the client.

trustStore

java.lang.String trustStore

Path to an optional truststore. If this is null or empty, the default JVM trust store is used. This is currently expected to be a signing certificate for the certification authority.

validateHostName

boolean validateHostName

If the flag ClientConfig.isEnableTls() is set, this flag decides whether to enable host name validation or not.

eventWriterConfig

EventWriterConfig eventWriterConfig

This writer config is used by the segment writers in the StateSyncrhonizer. The default values enable connection pooling and ensures the background connection retry attempts continue until the StateSyncrhonizer is closed.

readBufferSize

int readBufferSize

This size is used to allocate buffer space for the bytes the reader in the StateSyncrhonizer reads from the segment. The default buffer size is 256KB.

timestampAggregationTimeout

long timestampAggregationTimeout

Meaning that after this long of not calling EventStreamWriter.noteTime(long) the writer will be forgotten. If there are no known writers, readers that call EventStreamReader.getCurrentTimeWindow(Stream) will receive a `null` when they are at the corresponding position in the stream. which the timestamp should be considered valid before it is forgotten. be considered valid before it is forgotten.
