Name

The name of the data source. The name cannot be modified after the data source is created.

GeoEvent Definition

The GeoEvent Definition used to define the schema of the data source. The GeoEvent Definition cannot be modified after the data source is created.

Geometry Type

The type of geometry the data source will store. Available geometry types include point, polygon, polyline, multipoint, and no geometry. The geometry type cannot be modified after the data source is created.

Max Record Count

The maximum number of features to render or query. The max record count can be modified after the data source is created.

Replication Factor

Specifies the number of replicas, or copies, for each record to ensure resiliency. Specifying a replication factor of 0 tells the spatiotemporal data store to only create one copy, no replication. The default of 1 specifies that a single replica of the record will be created. Data replication only makes sense when multiple spatiotemporal data store nodes are available running on multiple servers for fault-tolerant operation.

Number of Shards

A data source is partitioned, or split, into multiple shards where each shard holds a portion of the data. The number of shards defines how many partitions of the data are created. Increasing the number of shards can increase indexing performance, but too many shards can reduce query performance.

Refresh Interval (seconds)

Specifies the time interval in seconds that new or updated events are indexed in the data source. Higher values will result in higher indexed events per second write speed performance, but it will increase the latency of written events being indexed and available for querying. A value of -1 disables data indexing, for a period of time, until the value is set back to a positive number. Dynamically changing the value to -1 and back for a period of time is useful for cases where there is a large number of events, allowing for a bulk indexing with better performance.

ObjectID Option

Specifies the type of ObjectID that is generated for feature records in the data source.

• Int64 ObjectID—Generates 64-bit numeric esriFieldTypeOID object identifiers. 64-bit identifiers are supported by ArcGIS Maps SDK for JavaScript clients and ArcGIS Maps SDK for .NET clients, including ArcGIS Online map viewer, custom JavaScript client applications, custom .NET client applications, and so on.
• Int32 ObjectID—Generates 32-bit numeric esriFieldTypeOID object identifiers. 32-bit identifiers are supported by all existing ArcGIS clients including ArcGIS Pro, ArcGIS Desktop, and more.
• Unique String Identifier—Generates string-based esriFieldTypeString identifier. String-based identifiers are supported by JavaScript clients including ArcGIS Online map viewer, custom JavaScript client applications, and more.

ObjectID Block Size

Specifies the number of object identifiers to allocate per request.

Rolling Data Option

Specifies the time after which the index is rolled and a new index is created. This helps with the distribution of data across many data sources versus having all of the data in one source, and thus improves searching and querying speeds. The data may be rolled on a century, decade, yearly, monthly, daily, or hourly basis. If GeoEvent Server is writing and storing large amounts of data to the spatiotemporal data store, set this parameter to Hourly, Daily, or Monthly to maintain optimal performance of the spatiotemporal data store.

When writing data, GeoEvent Server inspects the START_TIME attribute, or the RECEIVED_TIME attribute if no START_TIME is present.

Shrink Option

Specifies the shrink strategy for data shards that will be rolled over. When Shrink is selected, rolled-over data will be compressed into fewer shards. When No Shrink is selected, rolled-over data shards will not be compressed. While shrinking reduces the number of outstanding shards, thereby improving stability, compressing data reduces query performance.

Data Retention Option

(Optional)

Specifies the length of time data will be retained in the data source. After the time has expired, data will be purged from the data source. The minimum time data can be retained is 1 hour.

Data Retention Where

(Optional)

Specifies a WHERE clause for keeping or retaining specific features in the data source. Features that meet the WHERE clause will be retained when the data retention interval has lapsed.

Create

Specifies the type of services to create that reference the data in the data source. Options include map and feature services.

Spatial Reference

Specifies the spatial reference Well Known Identifier (WKID) or Well Known Text (WKT). The default value is 4326 (GCS WGS 1984).

Display Field Name

The name of the field to be used as the primary label field.

Background Color

Defines the background color of the map service. By default, the background color is fully transparent. Full transparency prevents any underlying base map from becoming obscured.

Add Aggregation Style

Add a new aggregation style for the map service. Supported styles include Geohash, Square, Flat Hexagon or Triangle, and Pointy Hexagon or Triangle. For each new style, define a spatial reference and level of detail (zoom).

Feature Threshold

Specifies the default number of features rendered by the map service before switching to an aggregation. For example, setting the feature threshold to a value of 200 means that up to 200 discrete features will be rendered by the map service. Any additional discrete features will cause the map service to render aggregated bins.

Add Aggregation Style

Add a new aggregation style for the map service or modify an existing aggregation style. Supported styles include Geohash, Square, Flat Hexagon or Triangle, and Pointy Hexagon or Triangle. For each new style, define a spatial reference and level of detail (scales).

Feature Threshold

Specifies the default number of features rendered by the map service before switching to an aggregation. For example, setting the feature threshold to 200 means that up to 200 discrete features will be rendered by the map service. Any additional discrete features will cause the map service to begin rendering data in aggregation view.

Aggregation Style

Defines the aggregation style used to aggregate features. Options include Geohash, Square, Flat Hexagon, Pointy Hexagon, Flat Triangle, and Pointy Triangle.

Bin Rendering Style

Defines the rendering style of the bin.

Aggregation Method

Specifies the method for calculating the aggregated bin value. Count defines the bin value using the raw number of features within each bin. Statistics calculates the value for each bin based on the field value from each feature and the statistic type.

Statistics Field

Specifies the field used for calculating the aggregated bin statistic value.

Statistics Type

Specifies the statistic method used for calculating the aggregated bin value. The type of statistic is applied to values in the Statistic Field parameter. The data type of the statistic field determines what type of statistic options are available. For example, choosing a string type field for the statistic field will provide Count and Count Distinct as options. Choosing an integer type field will provide Average, Maximum, Minimum, Standard Deviation, Sum, Variance, as well as Count and Count Distinct as options.

Show Labels

Defines whether to label each aggregation bin.

Label Style

Specifies the rendering style for labels in each aggregation bin including Font, Size, Style, Format, and Color. The default label style uses Arial, 12, plain, ###.##, and black.

Min Bin Size (pixels)

Specifies the minimum bin size by pixel count that will be used when creating bins for the largest level of detail (scales). The bin pixel size will not be smaller than the defined value. The default is 25 pixels.

LOD Offset

Specifies an optional offset value that is applied to the level of detail. Can be specified as a positive or negative integer value.

Bin Renderer

Specifies the rendering settings used for interpolating the aggregation bin rendering color and style.

• Range—Defines the minimum and maximum values in which the bin renderer will apply. A bin with a value equal to the minimum of the range uses the minimum of the fill color, outline color, and outline specified. The same condition applies to bins with a value equal to the maximum of the range. All other values in-between the range minimum and maximum are weight interpolated. The range is derived from the data if a fixed value is not provided (default).
• Fill Color—Defines the minimum and maximum fill color of the bin. The color gradient of the bins are interpolated based on the range minimum and maximum.
• Outline Color—Defines the minimum and maximum outline color of the bin. The color gradient of the bins outline are interpolated based on the range minimum and maximum.
• Outline Width—Defines the minimum and maximum outline width of the bin. The width of the outline for the bins is interpolated based on the range minimum and maximum.

Normalize By Bin Area

Specifies whether to normalize the bins by geographic area. Bins that appear the same size on a map can cover a different geographically size area. For example, a bin at the equator covers a larger geographic area than a bin at the north pole even though both are the same size on the map. Enabling normalization means that a bin at the equator will have a lighter color, while a bin at the north pole will have a darker color, assuming the fill color the maximum range value uses is a darker color than the minimum range value. Disabling normalization will treat all bins as the same size geographic area.

Style

Defines the simple marker symbol style for features with a point or multipoint geometry. Available options include Circle, Cross, Diamond, Square, X, Triangle, and Pointer.

Angle

Defines the number of degrees (0 to 360) the simple marker symbol is rotated for point and multipoint geometry. The rotation is from east in a counterclockwise direction where east is the 0 degree axis.

Color

Defines the color for each feature. It applies to all supported geometry types.

Size

Defines the size of each feature with a point or multipoint geometry.

Width

Defines the width of each feature with a polyline geometry.

Outline Color

Defines the outline color of each feature with a point, polygon, or multipoint geometry.

Outline Width

Defines the outline width of each feature with a point, polygon, or multipoint geometry.

X-OffSet

Defines the value, in pixels, to offset the discrete features on the X-axis.

Y-OffSet

Defines the value, in pixels, to offset the discrete features on the Y-axis.

Rotate Symbols (degree)

Allows you to dynamically rotate the simple marker symbol for point or multipoint features.

Rotation Type

Specifies the rotation type.

• Arithmetic—Zero is east and advances counterclockwise.
• Geographic—Zero is north and advances clockwise.

Rotation Field

Specifies the field from the data that has the angle of rotation value in degrees (0-360).

Time Interval

Specifies the time interval value representing a useful time step for the data in the data source. The time interval is used by client applications such as an ArcGIS Online web map that needs to set time-aware control settings. An example of a time-aware control setting is the step size for a time slider.

Time Interval Units

Defines the units for the Time Interval. Options include Milliseconds, Seconds, Minutes, Hours, Days, Weeks, Months, Years, Decades, or Centuries.

Has Live Data

Specifies whether the data source will have a live data feed. This setting is used by client applications needing to set time aware control settings.

Has Z

Specifies whether the services have Z geometry values

Enable Z Defaults

Specifies whether the services have a default Z geometry value

Z Default
