Zero Buffer

[MohammedAghil]

Is your feature request related to a problem? Please describe.
At present, The buffer implementations provide an asynchronous behavior, but there is a need to have a synchronous buffer mechanism to guaranteed immediate processing and direct synchronous flow of data from source to sink without buffering delays.
An example is Open Search API source where the data prepper events needs to be passed to in a synchronized way from source to sink.

Describe the solution you'd like

• Provides synchronous, immediate pass-through behavior
• Eliminates buffering delays by directly transferring data from write to read operations
• Implements the Buffer interface to maintain compatibility with existing Data Prepper components

Additional context

• Opensearch API source
