Blockchain Data Object Read Operation Properties

Blockchain Data Object Read Operation Properties

Create a blockchain data object read operation to read or to look up data on a blockchain. Use the read operation as a source or a lookup in a mapping.
For more information about read operations, see the
Informatica Developer Mapping Guide.

General Properties

The following table describes general properties for a read operation:
Property
Description
Name
Name of the data object operation.
Description
Description of the data object operation.

Ports Properties

The following table describes the port properties in the read operation:
Property
Description
Name
Name of the port.
Type
Data type of the port.
Detail
Type configuration for the port.
Precision
Maximum number of significant digits for numeric data types, or the maximum number of characters for string data types.
You can edit the precision based on your requirements. If the data exceeds the precision, the data is truncated.
Scale
Scale of the data type.
Description
Description of the port.

Run-time Properties

The following table describes the properties that the read operation uses at run time:
Property
Description
Connection
Name of the blockchain connection.

Advanced Properties

The following table describes the advanced properties for the read operation:
Property
Description
Operation Type
Type of blockchain data object operation. For a read operation, the operation type is
blockchainRead
.
Advanced Properties
Additional advanced properties for the operation. Advanced properties are name-value pairs that are separated by a semicolon.

Sources Properties

The following table describes the sources properties for the read operation:
Property
Description
Sources
Transactions that the blockchain data object operation uses to access an asset on the blockchain.
