Field Detail

TRUTH_MAINTENANCE

static final String TRUTH_MAINTENANCE

This optional boolean property may be used to specify whether or not RDFS entailments are maintained by eager closure of the knowledge base (the default is true). This property only effects data loaded through the Sail.

See Also:

(Manage Truth Maintenance)

DEFAULT_TRUTH_MAINTENANCE

static final String DEFAULT_TRUTH_MAINTENANCE

See Also:

Constant Field Values

BUFFER_CAPACITY

static final String BUFFER_CAPACITY

The capacity of the statement buffer used to absorb writes. If this capacity is exceeded, then an incremental flush will push assertions and/or retractions to the statement indices.

Note: With BLGZ-1522, the QUEUE_CAPACITY can increase the effective amount of data that is being buffered quite significantly. Caution is recommended when overriding the BUFFER_CAPACITY in combination with a non-zero value of the QUEUE_CAPACITY. The best performance will probably come from small (10k - 20k) buffer capacity values combined with a queueCapacity of 5-20. Larger values will increase the GC burden and could require a larger heap, but the net throughput might also increase.

See Also:

DEFAULT_BUFFER_CAPACITY

DEFAULT_BUFFER_CAPACITY

static final String DEFAULT_BUFFER_CAPACITY

See Also:

Constant Field Values

QUEUE_CAPACITY

static final String QUEUE_CAPACITY

Optional property specifying the capacity of blocking queue used by the StatementBuffer -or- ZERO (0) to disable the blocking queue and perform synchronous writes (default is "10" statements). The blocking queue holds parsed data pending writes onto the backing store and makes it possible for the parser to race ahead while writer is blocked writing onto the database indices.

See Also:

BLZG-1552

DEFAULT_QUEUE_CAPACITY

static final String DEFAULT_QUEUE_CAPACITY

See Also:

Constant Field Values

QUERY_TIME_EXPANDER

static final String QUERY_TIME_EXPANDER

Option (default true) may be used to explicitly disable query-time expansion for entailments NOT computed during closure. In particular, this may be used to disable the query time expansion of (x rdf:type rdfs:Resource) and owl:sameAs.

Note: Query time expanders are not supported in scale-out. They involve an expander pattern on the IAccessPath and that is not compatible with local reads against sharded indices. While it is possible to do remote access path reads on the shards and layer the expanders over the remote access path, this is not as efficient as using distributed local access path reads.

See Also:

DEFAULT_QUERY_TIME_EXPANDER

DEFAULT_QUERY_TIME_EXPANDER

static final String DEFAULT_QUERY_TIME_EXPANDER

See Also:

Constant Field Values

EXACT_SIZE

static final String EXACT_SIZE

Option (default false) determines whether the SailConnection.size(Resource[]) method returns an exact size or an upper bound. Exact size is a very expensive operation.

DEFAULT_EXACT_SIZE

static final String DEFAULT_EXACT_SIZE

See Also:

Constant Field Values

ALLOW_AUTO_COMMIT

static final String ALLOW_AUTO_COMMIT

Options (default false) added only to pass the Sesame test suites. DO NOT EVER USE AUTO-COMMIT WITH BIGDATA!

DEFAULT_ALLOW_AUTO_COMMIT

static final String DEFAULT_ALLOW_AUTO_COMMIT

See Also:

Constant Field Values

ISOLATABLE_INDICES

static final String ISOLATABLE_INDICES

Options (default false) creates the SPO relation with isolatable indices to allow read/write transactions.

DEFAULT_ISOLATABLE_INDICES

static final String DEFAULT_ISOLATABLE_INDICES

See Also:

Constant Field Values

NAMESPACE

static final String NAMESPACE

Option specifies the namespace of the designed KB instance (default "kb").

DEFAULT_NAMESPACE

static final String DEFAULT_NAMESPACE

See Also:

Constant Field Values

DESCRIBE_MODE

static final String DESCRIBE_MODE

Option specifies the algorithm used to compute DESCRIBE responses (optional).

See Also:

QueryHints.DESCRIBE_MODE, QueryHints.DEFAULT_DESCRIBE_MODE

DESCRIBE_ITERATION_LIMIT

static final String DESCRIBE_ITERATION_LIMIT

Option specifies the iteration limit for the algorithm used to compute DESCRIBE responses (optional).

See Also:

QueryHints.DESCRIBE_ITERATION_LIMIT, QueryHints.DEFAULT_DESCRIBE_ITERATION_LIMIT

DESCRIBE_STATEMENT_LIMIT

static final String DESCRIBE_STATEMENT_LIMIT

Option specifies the statement limit for the algorithm used to compute DESCRIBE responses (optional).

See Also:

QueryHints.DESCRIBE_STATEMENT_LIMIT, QueryHints.DEFAULT_DESCRIBE_STATEMENT_LIMIT

DEFAULT_FILE

static final String DEFAULT_FILE

The name of the default value used for the Journal.Options#FILE property by the BigdataSail.BigdataSail() convenience constructor.

See Also:

BigdataSail.BigdataSail(), Constant Field Values

REJECT_QUADS_IN_TRIPLE_MODE

static final String REJECT_QUADS_IN_TRIPLE_MODE

This optional boolean property may be used to specify whether quads in triple mode are rejected (true) or loaded while silently stripping off the context (false). In the latter case, the fireSailChangedEvent will report back the original statements, i.e. including the context, although the latter was not stored internally. This property only effects data loaded through the Sail.

DEFAULT_REJECT_QUADS_IN_TRIPLE_MODE

static final String DEFAULT_REJECT_QUADS_IN_TRIPLE_MODE
