USE_JTS

public static final ConfigProperty<Boolean> USE_JTS

Index option for enabling JTS integration

WRITE_BUFFER_SIZE

public static final Option<Integer> WRITE_BUFFER_SIZE

Lucene write buffer size

SPATIAL_ENABLED

public static final ConfigProperty<Boolean> SPATIAL_ENABLED

Option for whether or not spatial indexing is enabled for the database

SPATIAL_PRECISION

public static final ConfigProperty<Integer> SPATIAL_PRECISION

The precision used for spatial indexing. Corresponds to the precision of the underyling org.apache.lucene.spatial.prefix.tree.GeohashPrefixTree. The default value is 11 which results in sub-millimeter precision; a value of 8 will give a precision +/- 50m.

SPATIAL_DISTANCE_PRECISION

public static final ConfigProperty<Integer> SPATIAL_DISTANCE_PRECISION

Specifies the precision used for the distance calculations. The value is the number of significant digits distances used to represent distances. Smaller numbers sacrifice precision for performance. The default is 8. A value of -1 can be provided to compute distances to the maximum precision. The default value is 8.

SPATIAL_ERROR_PCT

public static final ConfigProperty<Double> SPATIAL_ERROR_PCT

SPATIAL_RESULT_PAGE_SIZE

public static final ConfigProperty<Integer> SPATIAL_RESULT_PAGE_SIZE

Page size used for iteration over results from the spatial index. Full name: spatial.result.page_size
Default value: 100

SPATIAL_RESULT_LIMIT

@Deprecated
public static final ConfigProperty<Integer> SPATIAL_RESULT_LIMIT

Deprecated.

Default max number of results from the spatial index. -1 returns all results Full name: spatial.result.limit
Default value: 10 000

OPTIMIZE

public static final ConfigProperty<Boolean> OPTIMIZE

SPATIAL_INDEX_DIRTY

public static final ConfigProperty<Boolean> SPATIAL_INDEX_DIRTY

LAST_COMMIT_TX

public static final InfoProperty<UUID> LAST_COMMIT_TX
