data from each connection using a configured record " +
+ "reader, and writes the records to a flow file using a configured
record writer. The type of record reader selected will " +
+ "determine how clients are expected to send data. For example,
when using a Grok reader to read logs, a client can keep an " +
+ "open connection and continuously stream data, but when using an
JSON reader, the client cannot send an array of JSON " +
+ "documents and then send another array on the same connection, as
the reader would be in a bad state at that point. Records " +
+ "will be read from the connection in blocking mode, and will
timeout according to the Read Timeout specified in the processor. " +
+ "If the read times out, or if any other error is encountered when
reading, the connection will be closed, and any records " +
+ "read up to that point will be handled according to the configured
Read Error Strategy (Discard or Transfer). In cases where " +
+ "clients are keeping a connection open, the concurrent tasks for
the processor should be adjusted to match the Max Number of " +
+ "TCP Connections allowed, so that there is a task processing each
connection.")
