TCP Server

Supported pipeline types:

  • Data Collector
The TCP Server origin listens at the specified port numbers, establishes TCP sessions with clients that initiate TCP connections, and then processes the incoming data. The origin can process data from tables with simple numeric primary keys. The origin cannot process data from tables with compound or non-numeric primary keys. For information about supported versions, see Supported Systems and VersionsSupported Systems and Versions in the Data Collector documentation.

The origin can operate in different modes. The modes determine the messages that it can process. It can process NetFlow messages or syslog messages. It can also process supported Data Collector data formats passed as data separated by specified characters, passed as character-based data with length prefixes, or passed in Flume events as Avro messages.

The TCP Server can process data from multiple clients simultaneously, creating separate batches for each client, and sending acknowledgements to the originating client after parsing each record or committing each batch. You can configure the origin to use multiple threads to improve performance when processing of large volumes of data. And on 64-bit Linux systems, you can enable native Epoll transports to further improve performance.

When you configure the TCP Server origin, you specify the ports to use and the TCP mode that indicates the type of data the origin will receive. Then you configure mode-related properties, such as the characters that separate records.

You can optionally configure the acknowledgements that you want to send and the amount of time that the origin waits to receive data before closing the connection. You can also configure SSL/TLS properties, including default transport protocols and cipher suites.
