It replaces the legacy assignment mechanism with a more sophisticated approach that considers multiple factors like agent capacity, availability, and conversation priority. + +## Purpose + +Instead of conversations sitting unassigned or being manually assigned one-by-one, Assignment v2 automatically distributes them across your team based on configurable rules and policies. This ensures: + +- **No conversations are left unassigned** — Open conversations get assigned to agents automatically +- **Fair workload distribution** — Conversations are spread evenly across the team +- **Respects agent capacity** — Agents don't get overloaded with too many conversations +- **Flexible prioritization** — You control how conversations are prioritized (oldest first vs. longest waiting) + +--- + +## How It Works: The Auto-Assignment Flow + +Assignment v2 operates through two parallel mechanisms: + +### 1. Real-time Assignment Trigger (AutoAssignmentHandler) + +The system monitors conversation changes in real-time through the `AutoAssignmentHandler` concern: + +- **Triggers on**: Every conversation save operation +- **Assignment occurs when**: + - A conversation transitions to `status: 'open'` with no assignee + - A conversation has an assignee who is no longer an inbox member +- **Action**: Immediately enqueues an `AutoAssignment::AssignmentJob` for that inbox +- **Fallback**: If assignment_v2 is not enabled, falls back to legacy `AgentAssignmentService` + +This ensures conversations get assigned immediately when they become eligible, without waiting for the periodic job. + +### 2. Periodic Assignment Cycle + +The system also runs a **30-minute cycle** through an automated job (`AutoAssignment::PeriodicAssignmentJob`) configured in `config/schedule.yml`: + +1. **Discovery Phase**: The system checks all accounts in batches + - Only accounts with the `assignment_v2` feature flag enabled are processed + - Uses `find_in_batches` for memory efficiency with large datasets + +2. **Queue Phase**: For each inbox in those accounts: + - Only inboxes with an `assignment_policy` linked are considered + - The inbox must have `enable_auto_assignment` set to true + - The linked assignment policy must be enabled + - An `AutoAssignment::AssignmentJob` is queued for each eligible inbox + +3. **Processing Phase**: Each assignment job: + - Fetches up to 100 unassigned, open conversations (configurable via `AUTO_ASSIGNMENT_BULK_LIMIT` env var) + - Processes conversations one at a time in the order determined by the priority policy + +4. **Assignment Phase**: For each conversation, the system: + - Checks if the conversation is assignable (open status, no current assignee) + - Finds agents who are available (online status) and have capacity + - Filters agents by rate limiting rules + - Selects one agent using the configured selection strategy + - Assigns the conversation to that agent + - Tracks the assignment in Redis for rate limiting + - Dispatches an `ASSIGNEE_CHANGED` event + +### Key Architectural Details + +- **Job Queues**: + - `PeriodicAssignmentJob` runs in the `scheduled_jobs` queue + - `AssignmentJob` runs in the `default` queue + +- **Batched Processing**: Uses `find_in_batches` for accounts and inboxes to handle large-scale deployments efficiently + +- **Error Handling**: + - Errors are logged with the inbox ID + - In test environments, errors are re-raised for debugging + - In production, errors don't crash the entire job cycle + +- **Conversation Limits**: Default is 100 conversations per job run, preventing memory issues and long-running jobs + +--- + +## Prerequisites & Feature Enablement + +Assignment v2 requires **all** of the following conditions to be met: + +1. **Account-Level Feature Flag**: The account must have the `assignment_v2` feature enabled (configured in `config/features.yml`) +2. **Assignment Policy**: An `AssignmentPolicy` must exist and be linked to the inbox via `InboxAssignmentPolicy` +3. **Policy Enabled**: The `AssignmentPolicy` must have `enabled: true` (acts as a soft switch) +4. **Inbox Auto-Assignment**: The inbox must have `enable_auto_assignment: true` + +If any of these conditions is not met, the inbox is skipped entirely and no assignments occur. The system checks these conditions via the `Inbox#auto_assignment_v2_enabled?` method. + +--- + +## Assignment Policies + +Policies determine HOW conversations are selected and assigned. Here are the main policies: + +### 1. Conversation Priority Policy + +**What it does**: Controls which conversations get assigned first + +**Options**: + +- **Longest Waiting Mode** (`longest_waiting`): + - Prioritizes conversations based on `last_activity_at` (oldest first) + - Uses `last_activity_at ASC, created_at ASC` ordering + - Ensures customers waiting longest for a response get priority + - Ideal for support teams focused on response time SLAs + +- **Default Mode** (or any other value): + - Conversations are assigned in the order they were created + - Uses `created_at ASC` ordering + - First In, First Out (FIFO) approach + - Ideal for teams that want to clear backlogs chronologically + +**Example**: +``` +Conversation A: Created 2 hours ago, last activity 2 hours ago +Conversation B: Created 1 hour ago, last activity 30 minutes ago +Conversation C: Created 30 minutes ago, last activity 30 minutes ago + +Longest Waiting: A → B → C (prioritizes least recent activity) +Default: A → B → C (prioritizes creation order) +``` + +### 2. Fair Distribution / Rate Limiting Policy + +**What it does**: Prevents any single agent from being overwhelmed by too many assignments in a short time window + +**Configuration**: +- `fair_distribution_limit`: Maximum number of assignments per agent within the time window (integer) +- `fair_distribution_window`: Time window in seconds (integer, defaults to 3600 seconds / 1 hour) + +**How it works**: +- When enabled, the system tracks each assignment in Redis +- Redis key pattern: `chatwoot:assignment:{inbox_id}:{agent_id}:{conversation_id}` +- Each key has a TTL (Time To Live) equal to the configured window +- Before assigning, the system counts existing keys for that agent +- If count >= limit, the agent is filtered out from eligible agents +- After assignment, a new Redis key is created with the window TTL + +**Behavior**: +- If `fair_distribution_limit` is not set or is 0, rate limiting is disabled +- Rate limiting is applied **per inbox per agent** +- Once the time window expires, old assignments are automatically removed from Redis +- Agents become eligible again once their count drops below the limit + +**Example**: +``` +Configuration: limit=5, window=3600 (1 hour) + +Agent A is assigned 5 conversations between 10:00-10:15am +At 10:16am, Agent A is filtered out (at limit) +At 11:01am (after the first assignment expires), Agent A is eligible again +``` + +**Edge Cases**: +- If ALL agents hit their rate limit, no assignments occur (0 assignments returned) +- Rate limits are checked AFTER agent availability but BEFORE capacity checks +- Rate limiting tracks assignments, not current workload (different from capacity) + +### 3. Agent Availability Policy + +**What it does**: Ensures only agents who are actually available get new conversations + +**How it works**: +- Uses `OnlineStatusTracker` to check real-time agent status +- Fetches all users with their status from Redis +- Only agents with status exactly equal to `'online'` are eligible +- Agents with status `'busy'`, `'offline'`, or any other value are filtered out + +**Integration**: +- The system calls `inbox.available_agents` which: + 1. Fetches online agent IDs from `OnlineStatusTracker` + 2. Filters inbox members to only those with online status + 3. Returns `InboxMember` records (not `User` records) + +**Edge Cases**: +- If no agents are online for an inbox, 0 assignments occur +- Agent availability is checked at the time of assignment (not when the job starts) +- If an agent goes offline mid-job, they won't receive more assignments + +**Important**: The system does NOT check: +- Agent's working hours +- Agent's timezone +- Agent's custom availability settings (these would need to be handled separately) + +### 4. Capacity Management Policy (Enterprise Feature) + +**What it does**: Advanced workload balancing based on agent's current load and conversation history + +**How it works**: +- Each agent can be assigned to an `AgentCapacityPolicy` +- The policy defines `InboxCapacityLimit` records (one per inbox) +- Each limit specifies a `conversation_limit` (integer) +- The system counts the agent's current **open** conversations in that specific inbox +- If `current_count >= conversation_limit`, the agent is filtered out + +**Key Characteristics**: +- **Inbox-specific**: Limits apply per inbox, so an agent can have different limits for different inboxes +- **Open conversations only**: Only counts conversations with `status: 'open'` +- **Optional**: If an agent has no `AgentCapacityPolicy`, they have unlimited capacity +- **Per-inbox limits**: If a capacity policy exists but has no `InboxCapacityLimit` for a specific inbox, the agent has unlimited capacity for that inbox + +**Example**: +``` +Agent A has a capacity policy with: +- Inbox 1 (Support): limit = 10 +- Inbox 2 (Sales): limit = 20 + +Agent A currently has: +- 10 open conversations in Inbox 1 +- 5 open conversations in Inbox 2 + +Result: +- Agent A is at capacity for Inbox 1 (10 >= 10) → filtered out +- Agent A has capacity for Inbox 2 (5 < 20) → eligible +``` + +**Edge Cases**: +- Resolved/closed conversations do NOT count toward capacity +- Capacity is checked at assignment time, not continuously +- If an agent goes over capacity manually (outside auto-assignment), they're still filtered out + +### 5. Exclusion Rules (Enterprise Feature) + +**What it does**: Allows excluding certain conversations from auto-assignment based on labels or age + +**Configuration** (on `AgentCapacityPolicy`): +```ruby +exclusion_rules = { + 'excluded_labels' => ['VIP', 'Escalation', 'Manual'], + 'exclude_older_than_hours' => 24 +} +``` + +**Behavior**: + +**Label-Based Exclusions**: +- Conversations tagged with any of the excluded labels are skipped +- Uses the `tagged_with` method with `exclude: true` +- Multiple labels are treated as OR (conversation with ANY excluded label is skipped) +- Label matching is exact (case-sensitive) + +**Age-Based Exclusions**: +- Conversations older than the specified hours are skipped +- Age is calculated from `created_at`, not `last_activity_at` +- Uses `where('conversations.created_at >= ?', hours.hours.ago)` +- If set to 24, conversations created more than 24 hours ago are excluded + +**Combined Exclusions**: +- Both rules are applied together (AND logic) +- A conversation must pass both checks to be eligible +- Example: Must be less than 24 hours old AND not have an excluded label + +**Edge Cases**: +- If `exclusion_rules` is nil or empty, no exclusions apply +- If there's no capacity policy linked to the inbox, exclusion rules don't apply +- Exclusions are applied BEFORE agent selection (reduces conversations to assign) + +--- + +## Selection Strategies + +Once eligible agents are identified (after availability, rate limiting, and capacity checks), the system uses a selection strategy to pick the agent: + +### Round-Robin (Default) + +**Implementation**: Uses `AutoAssignment::RoundRobinSelector` which delegates to `AutoAssignment::InboxRoundRobinService` + +**How it works**: +- Maintains a Redis-based queue of agent IDs for the inbox +- Each time an agent is selected, they're moved to the back of the queue +- The next agent in the queue is always selected +- Ensures even distribution over time + +**Characteristics**: +- **Fair over time**: Each agent gets an equal turn +- **Stateful**: Uses Redis to maintain queue state across jobs +- **Inbox-specific**: Each inbox has its own round-robin queue + +**Example**: +``` +Queue: [Agent A, Agent B, Agent C] + +Assignment 1: Agent A (queue becomes [Agent B, Agent C, Agent A]) +Assignment 2: Agent B (queue becomes [Agent C, Agent A, Agent B]) +Assignment 3: Agent C (queue becomes [Agent A, Agent B, Agent C]) +``` + +**Edge Cases**: +- If an agent is removed from the inbox, they're removed from the queue +- If a new agent is added, they're added to the queue +- The queue is validated and reset if it becomes inconsistent (membership drift) +- The `InboxRoundRobinService` validates the queue and resets it when agent membership changes + +### Balanced / Workload-Based (Enterprise) + +**Implementation**: Uses `Enterprise::AutoAssignment::BalancedSelector` + +**How it works**: +- For each eligible agent, counts their current **open** conversations in the inbox +- Selects the agent with the **minimum** count +- Uses `min_by` which returns the first agent if there's a tie + +**Characteristics**: +- **Real-time balancing**: Based on current workload, not historical assignments +- **Inbox-specific**: Only counts conversations in the specific inbox +- **Open conversations only**: Ignores resolved/closed conversations +- **Prioritizes new agents**: Agents with 0 conversations are always selected first + +**Example**: +``` +Agent A: 5 open conversations +Agent B: 3 open conversations +Agent C: 8 open conversations + +Selection: Agent B (has the least workload) + +After assignment: +Agent A: 5, Agent B: 4, Agent C: 8 +Next selection: Agent B again (still has least) +``` + +**Comparison**: + +| Aspect | Round-Robin | Balanced | +|--------|-------------|----------| +| **Goal** | Equal distribution over time | Equal workload at any moment | +| **State** | Redis queue | Database query | +| **Speed** | Very fast (Redis lookup) | Slower (DB count query) | +| **Accuracy** | Equal turns, not equal workload | Equal workload | +| **Best for** | High-volume, fast assignments | Teams where agents have varying resolve rates | + +**Configuration**: +- In OSS: Always uses Round-Robin +- In Enterprise: Can set `balanced: true` on the assignment policy to use Balanced strategy + +--- + +## Important Behaviors & Edge Cases + +### Conversation Eligibility + +A conversation is only eligible for auto-assignment if ALL of the following are true: + +1. **Status is 'open'**: Resolved, pending, or snoozed conversations are never assigned +2. **No current assignee**: Conversations with an existing assignee are never reassigned +3. **Passes exclusion rules** (if Enterprise): Must not have excluded labels and must be within age threshold +4. **In an eligible inbox**: The inbox must have auto-assignment v2 enabled + +**Edge Cases**: +- If a conversation is manually assigned mid-job, it's skipped (already has assignee) +- If a conversation is resolved mid-job, it's skipped (no longer open) +- Assignment v2 NEVER reassigns conversations (even if the current agent goes offline) + +### Agent Eligibility + +An agent is only eligible for assignment if ALL of the following are true: + +1. **Member of the inbox**: Agent must be an `InboxMember` +2. **Status is 'online'**: Checked via `OnlineStatusTracker` at assignment time +3. **Within rate limit** (if configured): Agent hasn't exceeded assignments in the current window +4. **Has capacity** (if Enterprise): Agent's open conversation count is below their limit for this inbox + +**Edge Cases**: +- If an agent meets all criteria but goes offline between the eligibility check and assignment, they may still receive the conversation (race condition) +- If ALL agents are filtered out, the conversation remains unassigned until the next cycle + +### Zero-Assignment Scenarios + +The system may assign 0 conversations if: + +1. No unassigned, open conversations exist in the inbox +2. All conversations are excluded by exclusion rules +3. No agents are online +4. All online agents are at their rate limit +5. All online agents are at capacity (Enterprise) +6. The assignment policy is disabled mid-job + +### Assignment Events + +When a conversation is successfully assigned, the system: + +1. Updates the conversation's `assignee_id` in the database +2. Creates a Redis key to track the assignment (for rate limiting) +3. Dispatches an `Events::Types::ASSIGNEE_CHANGED` event with: + - `conversation`: The conversation object + - `user`: The assigned agent + - Timestamp of the assignment + +**Event Integration**: +- Webhooks subscribed to `ASSIGNEE_CHANGED` will be triggered +- The conversation model also dispatches a `conversation.updated` event +- These events can be used for notifications, integrations, or analytics + +### Error Handling + +**Job-Level Errors**: +- If an `AssignmentJob` encounters an error, it logs the error with the inbox ID +- In production, the error is caught and logged, allowing other jobs to continue +- In test environment, errors are re-raised for debugging + +**Service-Level Errors**: +- If a single conversation assignment fails, it's skipped and the job continues +- The `assigned_count` only includes successful assignments +- Database errors (like constraint violations) are logged but don't stop the job + +**Graceful Degradation**: +- If Redis is unavailable, rate limiting is skipped (all assignments proceed) +- If OnlineStatusTracker fails, no agents are considered online (0 assignments) +- If the inbox is deleted mid-job, the job exits early + +### Performance Considerations + +**Batch Processing**: +- Accounts are processed in batches to avoid loading all accounts into memory +- Inboxes are processed in batches to avoid loading all inboxes into memory +- Conversations are limited to 100 per job to prevent long-running jobs + +**Redis Usage**: +- Rate limiting creates one Redis key per assignment +- Keys automatically expire based on the configured window +- Pattern matching (`keys_count`) is used to count assignments (can be expensive with many agents) + +**Database Queries**: +- Uses `includes(:user)` in `InboxAgentAvailability#available_agents` to preload users and avoid N+1 queries +- Falls back to `inbox_members.none` when no agents are online to avoid unnecessary database hits +- Uses `group(:assignee_id).count` for balanced selector (efficient aggregation) +- Uses `limit(100)` to prevent loading thousands of conversations at once + +**Scaling Recommendations**: +- For high-volume inboxes, increase `AUTO_ASSIGNMENT_BULK_LIMIT` (e.g., 200-500) +- Consider shorter rate limiting windows for faster cycling (e.g., 1800 seconds instead of 3600) +- Use balanced selector for teams where workload balance is critical + +--- + +## API Endpoints + +Assignment v2 provides REST API endpoints for managing assignment policies: + +### Policy Management +- **CRUD Operations**: `Api::V1::Accounts::AssignmentPoliciesController` + -
