Adapters are programs that convert data to and from the StreamBase tuple protocol. You can use adapters to:
Convert data from real-time sources such as financial market data feeds.
Convert data from an external resource such as a CSV file.
Convert processed StreamBase tuples into the format used by an external resource, such as an XML file.
StreamBase provides two categories of adapters:
- Embedded Adapters
Embedded adapters are those that run in the same StreamBase Server process that is hosting and processing your StreamBase application, and do not incur any client-server communication overhead. Embedded adapters start and stop automatically with the StreamBase application, which simplifies administration and deployment of your application.
The base StreamBase installation includes all of the available embedded adapters. See Embedded Adapters for the available embedded adapters.
- External Adapters
External adapters are those that run in independent processes separate from the StreamBase Server process, and possibly on separate hosts. External adapters are provided in separate installation kits. See External Adapters for the available external adapters.
The development license provided with StreamBase trial kits enables all embedded and external adapters for the limited term of the license (usually 30 to 60 days after you download the trial kit). After your trial kit license expires, contact StreamBase Systems for continued access to the adapters of interest.
If you need functionality not provided by an existing StreamBase adapter, you can implement your own custom embedded adapter using the StreamBase Java Client library. See Creating Custom Java Embedded Adapters for more information.
