Field descriptions

Field	Type	Required	Description	Constraints
name	string	yes	The name of the satellite.	should be unique
technicalDescription	string	no	The technical description of the satellite.
businessDescription	string	no	The business description of the satellite.
isMultiActive	boolean	yes	Whether or not this satellite is multi-active. i.e. whether several satellite entries for the same hash key can be valid.
subsequenceColumnName	string	no	If the satellite is multi-active, and this is null, the satellite will be a classical VTCP satellite. All data loads will create new entries for the satellite. If this points to the `columnName` of one of the columns, the satellite will be a delta-driven satellite. A hash diff column will be computed to only load multi-active sets that change.	Has to be the name of a column that exists.
columns	array of objects	yes	The list of columns of the satellite.
columns.businessName	string	no	The business name of the column.
columns.columnName	string	yes	The name of the column.
columns.defaultValue	string	no	The default value of the column, i.e. the DEFAULT database values.
columns.description	string	no	The description of the column.
columns.required	boolean	yes	If true, the column should contain a value, i.e. NOT NULL. In practice, this is informative, as all columns in a satellite are forced to be nullable.
columns.order	integer	true	The index of the column.	Should be unique.
columns.dataType	string	yes	The name of the type of the column. This is one of .NET’s `System.Data.DbType` values. https://learn.microsoft.com/en-us/dotnet/api/system.data.dbtype?view=net-8.0
columns.length	integer	no	The length of the type.	Relevant for column types that have length, like char or byte strings.
columns.precision	integer	no	The precision of the type.	Relevant for column types that have precision like decimal.
columns.scale	integer	no	The scale of the type.	Relevant for column types that have scale like decimal.
columns.isComputed	boolean	yes	Saved, but purely informative
columns.isSequence	boolean	yes	Saved, but purely informative

Response fields

Field	Type	Description
id	string	The app-generated id of the satellite.
name	string	The name of the satellite, as used in the database.
displayName	string	The chosen name of the satellite.
businessDescription	string	The business description of the satellite.
technicalDescription	string	The technical description of the satellite.
deployedInProduction	boolean	deprecated always false
entityType	string	always “Satellite”
tableName	string	The default technical name that will be used when trying to deploy this entity’s table.
isMultiActive	boolean	Whether or not this satellite is multi-active. i.e. whether several satellite entries for the same hash key can be valid.
subSequenceColumn	object	If the satellite is multi-active, and this is null, the satellite is a classical VTCP satellite. If this is one of the satellite’s columns, the satellite will be a delta-driven satellite. For detials about this object’s fields, see the `columns` array below.
