Adapter type: randomtuplegen_in. The Random Tuples Generator adapter generates random tuples according to the given schema and sends the rows to the stream.
A tuple is an ordered list of elements, or in other words, a row of data. A row that has two column values is a 2-tuple, and generally, a row that has n column values is an n-tuple. The adapter is primarily used for prototyping and basic testing of Event Stream Processor. You can edit both the schema and configuration file.
If you use the CCL ATTACH ADAPTER statement to attach an adapter, you must supply the adapter type.
| Property Label | Property ID | Type | Description |
|---|---|---|---|
| Rate | Rate | uint |
(Optional) Number of rows generated per second. Must be between 0 (inclusive) and 1,000,000 (inclusive). If Rate is negative, the adapter stops and returns a fatal error message to the Server. If Rate is larger than the maximum value, it resets to the maximum and reports a warning message to the Server. If Rate property is blank, it resets to the default value and reports a message. Default value is 100. |
| Row Count | RowCount | uint |
(Optional) Specifies number of generated rows. Must be between 0 and 2,000,000,000 inclusive. If RowCount is negative, the adapter stops and returns a fatal error message to the Server. If RowCount is larger than the maximum value, it resets to the maximum and reports a warning message to the Server. If RowCount property is blank, it resets to the default value and reports an information message to the Server. Default value is 0, which represents an infinite number of rows. |
| Timestamp Base | TimestampBase | string |
(Optional) Initial time for message timestamps. The supported format of TimestampBase is %Y-%m-%dT%H:%M:%S. If TimestampBase is blank, it resets to default value and the adapter initializes immediately. Similarly, the adapter initializes immediately if the TimestampBase value is earlier than current time. If TimestampBase value is later than current time, the adapter sleeps until then. If TimestampBase has an invalid timestamp format, the adapter stops and returns a fatal error message to the Server. Default value is the current time. |
| Date Format | DateFormat | string | (Optional) Format string for parsing date values. Default value is %Y-%m-%d %H:%M:%S. |
| Timestamp Format | TimestampFormat | string | (Optional) Format string for parsing date values. Default value is %Y-%m-%d %H:%M:%S. |
|
PropertySet |
propertyset | string |
(Advanced) Specifies the name of the property set from the project configuration file. If you specify the same properties in the project configuration file and the ATTACH ADAPTER statement, the values in the property set override the values defined in the ATTACH ADAPTER statement. No default value. |
| Block Size | blockSize | int | (Advanced) The number of records to block into one pseudo-transaction. Default value is 0. |
|
Use Envelopes |
useEnvelopes | boolean |
(Advanced) Specify the block type the adapter uses to pass data to the engine. If you specify a blockSize property greater than zero, by default, the adapter packages rows into transaction blocks to send to the engine. To get the adapter to package rows into envelope blocks instead, set this property to true. Default value is false. |
The data this adapter generates is not evenly distributed across the range of possible values for each datatype. This table shows the value range generated for each datatype:

0.0 .. 10.0 exclusive (should never get 10.0) |
| interval |
0 .. 9 inclusive |
| timestamp |
