Overview

Batch publisher for efficient bulk event publishing.

BatchPublisher allows you to queue multiple events and publish them together, providing detailed results about successes and failures. Each event is published independently, so partial failures are possible.

Examples:

Publishing multiple events

results = JetstreamBridge.publish_batch do |batch|
  users.each do |user|
    batch.add(event_type: "user.created", payload: { id: user.id })
  end
end

puts "Published: #{results.successful_count}, Failed: #{results.failed_count}"
results.errors.each { |e| logger.error("Failed: #{e[:event_id]}") }

Checking for failures

results = JetstreamBridge.publish_batch do |batch|
  batch.add(event_type: "order.created", payload: { id: 1 })
  batch.add(event_type: "order.updated", payload: { id: 2 })
end

if results.failure?
  logger.warn "Some events failed to publish"
end
