Open Adapter Components

Add at least one source and one sink component to use the Open adapter. Source components read provided data, and sink components write to associated output.

Each component has its own required properties. Set the DOStringReader and DOStringWriter properties for the source and sink components to enable data passing through these components to be parsed and formatted by various parsers and formatters.

Event Stream Processor does not support multibyte character sets, such as UTF-16. However, an external source may contain non-ASCII characters. By default, the adapter interprets them as 1-byte or 2-byte Unicode characters, which may lead to data corruption. To set the encoding explicitly, add the TextEncoding property to the configuration file. For example:

Adapter. Component.TextEncoding=ASCII

If a property for defining multiple table names is specified as:

Adapter. Component.Table++=TableName

Adapter. Component.Table1=TableName1
Adapter. Component.Table2=TableName2

You can define properties with a number of levels separated by a period. For example, a property specific to Table1 can be represented as:

Adapter. Component.TableName1.Field1=FieldName1
