public static final class CreateGraphRequest.Options extends Object
RESTRICTION_THRESHOLD_VALUE
: Value-based restriction comparison. Any
node or edge with a RESTRICTIONS_VALUECOMPARED value greater than the
restriction_threshold_value
will not be included in the graph.
MERGE_TOLERANCE
: If node geospatial positions are input (e.g.,
WKTPOINT, X, Y), determines the minimum separation allowed between
unique nodes. If nodes are within the tolerance of each other, they will
be merged as a single node. The default value is '1.0E-4'.
MIN_X
: Minimum x (longitude) value for spatial graph associations. The
default value is '-180.0'.
MAX_X
: Maximum x (longitude) value for spatial graph associations. The
default value is '180.0'.
MIN_Y
: Minimum y (latitude) value for spatial graph associations. The
default value is '-90.0'.
MAX_Y
: Maximum y (latitude) value for spatial graph associations. The
default value is '90.0'.
RECREATE
: If set
to true
and the graph (using graphName
) already exists,
the graph is deleted and recreated.
Supported values:
The default value is FALSE
.
MODIFY
: If set to true
, recreate
is set to true
, and the graph (specified using graphName
) already exists,
the graph is updated with the given components.
Supported values:
The default value is FALSE
.
EXPORT_CREATE_RESULTS
: If set to true
, returns the graph
topology in the response as arrays.
Supported values:
The default value is FALSE
.
ENABLE_GRAPH_DRAW
: If set to true
, adds a 'EDGE_WKTLINE' column
identifier to the specified graph_table
so the graph can be
viewed via WMS; for social and non-geospatial graphs, the 'EDGE_WKTLINE'
column identifier will be populated with spatial coordinates derived
from a flattening layout algorithm so the graph can still be viewed.
Supported values:
The default value is FALSE
.
SAVE_PERSIST
: If set to true
, the graph will be saved in the
persist directory (see the config reference for more information). If set to
false
, the graph will be removed when the graph server is
shutdown.
Supported values:
The default value is FALSE
.
SYNC_DB
: If set
to true
and save_persist
is set to true
, the
graph will be fully reconstructed upon a database restart and be updated
to align with any source table(s) updates made since the creation of the
graph. If dynamic graph updates upon table inserts are desired, use
add_table_monitor
instead.
Supported values:
The default value is FALSE
.
ADD_TABLE_MONITOR
: Adds a table monitor to every table used in the
creation of the graph; this table monitor will trigger the graph to
update dynamically upon inserts to the source table(s). Note that upon
database restart, if save_persist
is also set to true
,
the graph will be fully reconstructed and the table monitors will be
reattached. For more details on table monitors, see GPUdb.createTableMonitor(CreateTableMonitorRequest)
.
Supported values:
The default value is FALSE
.
GRAPH_TABLE
:
If specified, the created graph is also created as a table with the
given name and following identifier columns: 'EDGE_ID', 'EDGE_NODE1_ID',
'EDGE_NODE2_ID'. If left blank, no table is created. The default value
is ''.
REMOVE_LABEL_ONLY
: When RESTRICTIONS on labeled entities requested, if
set to true this will NOT delete the entity but only the label
associated with the entity. Otherwise (default), it'll delete the label
AND the entity.
Supported values:
The default value is FALSE
.
ADD_TURNS
: Adds
dummy 'pillowed' edges around intersection nodes where there are more
than three edges so that additional weight penalties can be imposed by
the solve endpoints. (increases the total number of edges).
Supported values:
The default value is FALSE
.
TURN_ANGLE
:
Value in degrees modifies the thresholds for attributing right, left,
sharp turns, and intersections. It is the vertical deviation angle from
the incoming edge to the intersection node. The larger the value, the
larger the threshold for sharp turns and intersections; the smaller the
value, the larger the threshold for right and left turns; 0 < turn_angle
< 90. The default value is '60'.
