Class BufferSubscriber

java.lang.Object

com.epam.reportportal.service.logs.BufferSubscriber

All Implemented Interfaces:

io.reactivex.FlowableSubscriber<com.epam.ta.reportportal.ws.model.log.SaveLogRQ>, org.reactivestreams.Subscriber<com.epam.ta.reportportal.ws.model.log.SaveLogRQ>, org.reactivestreams.Subscription

public class BufferSubscriber
extends java.lang.Object
implements io.reactivex.FlowableSubscriber<com.epam.ta.reportportal.ws.model.log.SaveLogRQ>, org.reactivestreams.Subscription

A subscriber that buffers incoming SaveLogRQ objects until certain conditions are met, then emits them as batches to the downstream subscriber.

This class implements a buffering mechanism with two boundary conditions:

• Maximum number of log items in a batch (specified by batchMaxSize)
• Maximum payload size of a batch in bytes (specified by batchPayloadLimit)

When either of these conditions is met, the current buffer is emitted downstream as a list and a new buffer is created. This helps optimize network requests by batching multiple logs together while ensuring the batch size remains within reasonable limits.

The class is thread-safe, using a ReentrantLock to protect access to the buffer during concurrent operations.
