// Buffer defines a buffer used to store records streamed through Kinesis. It is a part of the
// Pipeline utilized by the Pipeline.ProcessShard function. Records are stored in the buffer by calling
// the Add method. The buffer has two size limits defined: total total number of records and a
// time limit in seconds. The ShouldFlush() method may indicate that the buffer is full based on
// these limits.
