Modifier and Type	Field and Description
boolean	describeEachNamedGraph When true and the KB instance is in the quads mode, each named graph will also be described in in the same level of detail as the default graph.
long	executorMaxThreads Executor service thread limit.
String	namespace The default namespace.
int	queryThreadPoolSize The #of threads to use to handle SPARQL queries -or- ZERO (0) for an unbounded pool.
long	queryTimeout When non-zero, this specifies the timeout (milliseconds) for a query.
boolean	readOnly When true, requests will be refused for mutation operations on the database made through the REST API.
long	timestamp The default timestamp used to query the default namespace.

Field Detail

namespace

public final String namespace

The default namespace.

See Also:

ConfigParams.NAMESPACE

timestamp

public final long timestamp

The default timestamp used to query the default namespace. The server will obtain a read only transaction which reads from the commit point associated with this timestamp.

Note: When ConfigParams.READ_LOCK is specified, the timestamp will actually be a read-only transaction identifier which is shared by default for each query against the NanoSparqlServer.

See Also:

ConfigParams.READ_LOCK

queryThreadPoolSize

public final int queryThreadPoolSize

The #of threads to use to handle SPARQL queries -or- ZERO (0) for an unbounded pool.

See Also:

ConfigParams.QUERY_THREAD_POOL_SIZE

describeEachNamedGraph

public final boolean describeEachNamedGraph

When true and the KB instance is in the quads mode, each named graph will also be described in in the same level of detail as the default graph. Otherwise only the default graph will be described.

See Also:

ConfigParams.DESCRIBE_EACH_NAMED_GRAPH

readOnly

public final boolean readOnly

When true, requests will be refused for mutation operations on the database made through the REST API. This may be used to help lock down a public facing interface.

See Also:

ConfigParams.READ_ONLY

queryTimeout

public final long queryTimeout

When non-zero, this specifies the timeout (milliseconds) for a query. This may be used to limit resource consumption on a public facing interface.

See Also:

ConfigParams.QUERY_TIMEOUT

executorMaxThreads

public final long executorMaxThreads

Executor service thread limit. This is a soft boundary - actual pool will be unlimited, but new queries would not be launched if the pool has more active threads than this. If zero, there is no limit.

ConfigParams.EXECUTOR_SERVICE_MAX_THREADS
