What is DynamoDB Console? Web-based interface in AWS Management Console for managing DynamoDB tables. Create tables, add/edit items, monitor performance, manage capacity, backup data—all without writing code.

How to Access Console: (1) Go to console.aws.amazon.com. (2) Search for “DynamoDB” or find under “Database” services. (3) Click “DynamoDB” → opens DynamoDB dashboard. (4) You’re in the console.

Main Console Sections: Tables (list of your tables), Dashboard (overview, monitoring), Global tables (multi-region), Backups (snapshots), Monitoring (CloudWatch metrics), TTL settings, Streams.

Left Navigation Menu: Tables (create, browse, manage), Exports (export data to S3), Global tables (replication), Backups, Capacity, Monitoring, Settings. Most work happens in “Tables” section.

Best for Beginners: Console is most intuitive way to start. Click, fill forms, done. Advanced users often use CLI/SDK (faster), but console essential for quick tasks, troubleshooting, monitoring.

Step 1: Click “Create Table” In DynamoDB console, orange “Create table” button (top-right). Opens table creation form.

Step 2: Enter Table Name Name must be unique in region. Example: “Users”, “Products”, “Orders”. Alphanumeric + underscores. Cannot change after creation (must delete + recreate).

Step 3: Set Partition Key CRITICAL! Choose attribute for partition key. Example: user_id (for users table). This determines how data distributed. Choose carefully—can’t change without recreating table. Example: user_id (String) for user lookup.

Step 4: Add Sort Key (Optional) Secondary key for sorting. Example: timestamp (for storing posts by user, sorted by time). If you need range queries (get all posts from user_id=123, created between Jan-Feb), add sort key. If simple lookups only (just get user by ID), leave empty.

Step 5: Choose Capacity Mode On-Demand (pay per request, unpredictable traffic) or Provisioned (reserve capacity upfront, predictable traffic). Default: On-Demand (easiest for beginners). Can change later.

Step 6: Click Create Table created in ~1 minute. DynamoDB initializes infrastructure, replicates across AZs. Table ready to use when status changes to “Active”.

Viewing Items: Click table → “Explore table items” tab. Shows all items in table. Displays partition key, sort key (if exists), other attributes. Default: paginated (100 items per page).

Creating New Item (Adding Data): Click “Create item” button. Form opens. Enter partition key value (required). Add other attributes via “Add new attribute” button. Types: String, Number, Binary, Boolean, Null, List, Map. Example: {user_id: “123”, name: “Alice”, email: “alice@example.com”, age: 30}. Click “Create item” → item added to table in <1ms.

Viewing Specific Item: Click on item in list. Opens item details. Shows all attributes. View only (can’t edit directly from this view in newer console).

Editing Item: Click item → Edit icon. Modify attributes, add new attributes, delete attributes. Click Save. Changes live immediately.

Deleting Item: Select item checkbox → Delete button appears. Confirm deletion. Item removed from table permanently (can’t undo).

Query vs Scan: Query: find items with specific partition key (fast, <1ms). Scan: read entire table (slow, proportional to table size). Always prefer Query when possible.

Using Query Feature: Click “Query” button in Explore tab. Select table, enter partition key value. Optional: enter sort key range (e.g., created_at >= 2024-01-01). Click “Run” → results show matching items. Example: user_id = “123” → returns all items for user 123.

Using Scan Feature: Click “Scan” button. Returns ALL items in table (dangerous for large tables!). Optional: add filter (e.g., age > 25). Click “Run” → results show all items matching filter. Warning: scanning 1M item table = slow + expensive.

Adding Filters: Both Query and Scan allow filters (additional conditions). Example: Query user_id=”123″, Filter age > 25 (gets all user 123’s items where age > 25). Filters applied AFTER data retrieved (less efficient than key conditions).

Console Query Limitations: GUI works for simple queries only. Complex filters or batch operations need CLI/SDK. For advanced: use AWS CLI (`aws dynamodb query`) or write code (Python boto3, Node.js SDK).

What are Indexes? Alternative access path to data. Primary table indexed by partition key. Indexes allow queries on different attributes. Example: Users table indexed by user_id. Need to find user by email? Create Global Secondary Index (GSI) on email attribute.

Creating GSI in Console: Open table → Indexes tab → “Create Global Secondary Index”. Choose attribute for index partition key (e.g., email). Optional: choose sort key. Select capacity mode (on-demand/provisioned). Click Create. Index created in ~1 minute (backfill from primary table). Cost: additional storage + capacity for index.

Querying via GSI: In Query screen, drop-down menu “Choose index”. Select GSI (e.g., email-index). Enter email value → finds user by email instead of user_id. Performance same as primary table (<1ms).

Deleting Index: Open table → Indexes tab → GSI row → Delete button. Confirmed deletion removes index (immediate). Capacity freed, cost drops.

LSI (Local Secondary Index): Like GSI but limited (10GB max per partition key). Must specify at table creation (can’t add later). Use only if <10GB data per partition key and specific use case. Usually GSI is better.

Console Monitoring Tab: Table overview → “Monitoring” tab. Shows live metrics: read capacity used, write capacity used, provisioned capacity, latency, errors. Charts update every minute. Useful for spotting issues.

CloudWatch Integration: Console shows basic metrics. For advanced: click “View in CloudWatch” → opens CloudWatch dashboard with detailed metrics (latency percentiles, throttling, item counts, etc.). CloudWatch allows custom alarms (alert if throttling detected).

Key Metrics to Watch: ConsumedReadCapacityUnits (actual read usage), ConsumedWriteCapacityUnits (actual write usage), ProvisionedReadCapacityUnits (reserved capacity), ProvisionedWriteCapacityUnits (reserved capacity), UserErrors (client errors), SystemErrors (AWS errors), Latency (response time).

Spotting Problems: If ConsumedReadCapacityUnits > ProvisionedReadCapacityUnits → throttling (requests rejected). Fix: increase provisioned capacity or switch to on-demand. High Latency → table hot, index needed or query inefficient.

Setting Alarms in CloudWatch: Console → Monitoring → “Create alarm”. Example: alert if ConsumedReadCapacityUnits > 80% of provisioned. Essential for production (catch issues before customers complain).

Provisioned Capacity Mode: You reserve read/write capacity upfront. Table → Capacity tab. Set Read capacity units (RCU) and Write capacity units (WCU). 1 RCU = 1 strongly-consistent read/sec (4KB). 1 WCU = 1 write/sec (1KB). Example: reserve 100 RCU, 50 WCU. Paying for those units whether you use them or not.

Scaling Capacity in Console: Table → Capacity tab → Edit capacity. Increase/decrease RCU/WCU. Change takes effect immediately (new capacity provisioned). If you decrease, takes effect after 1 hour (safety buffer). Cost recalculated.

Throttling (Problem): If requests exceed provisioned capacity, DynamoDB throttles (returns 400 error “ProvisionedThroughputExceededException”). Clients can retry. Fix: increase capacity in console or switch to on-demand.

Auto-Scaling (Optional): Console → Capacity tab → Auto-Scaling toggle. If enabled, DynamoDB automatically increases capacity when usage spikes (up to 40K RCU/WCU). Costs more but prevents throttling. Useful for variable workloads.

On-Demand Mode: No capacity management needed. Pay $0.25/million reads, $1.25/million writes. Scale automatically, no throttling. Higher per-request cost but simpler. Good for unpredictable traffic.

Point-in-Time Recovery (PITR): Automatic, enabled by default. Restores table to any point in time (up to 35 days ago). Useful: accidentally deleted important data? Restore from 1 hour ago. Table → Backups → Restore to point in time. Select date/time. Confirm. New table created with restored data.

Manual Backups (Snapshots): Table → Backups → Create backup. Snapshot taken immediately (copy of entire table). Can restore anytime (even years later, unlimited retention). Costs: storage of backup (~$0.10/GB/month). Use for: major changes (before upgrade), compliance (keep 7-year history).

Restoring Backup: Backups tab → Select backup → Restore. Choose new table name (can’t restore over existing table). New table created with backup data. Takes 1-5 minutes depending on size. Capacity reset to table’s current settings.

Exporting Data: Table → Export/Import → Export to S3. Select S3 bucket, path, format (DynamoDB JSON or standard JSON). Export runs in background. Data written to S3 (can download, analyze, backup). Useful: data analytics, backup to cheaper storage, compliance.

Importing Data: From S3 JSON file back to DynamoDB. Table → Export/Import → Import from S3. Select S3 file. Import runs. Useful: restore from manual backup in S3, load test data, migrate from another database.

What is TTL? Auto-delete items after expiration. Example: session storage—expire sessions 24 hours after creation. Items automatically deleted by DynamoDB (no manual cleanup). Saves storage, reduces cost.

Enabling TTL in Console: Table → “Time to live (TTL)” tab. Click “Manage TTL”. Select attribute for TTL (must be Number type, Unix timestamp in seconds). Example: expiration_time attribute. Click “Enable”. TTL activated. Items with expiration_time in past deleted automatically (within 48 hours, DynamoDB doesn’t guarantee exactly when).

Setting TTL When Creating Item: Add attribute: expiration_time = Unix timestamp. Example: current time + 86400 (1 day). Item automatically deleted after that time. No manual intervention.

Common Uses: Sessions (expire after 24 hours), OTPs (one-time passwords, expire after 10 minutes), cache data (expire after 1 hour), temporary uploads (expire after 7 days).

Important: TTL is approximate (48-hour window). Don’t rely on exact expiration for security (e.g., authorization tokens). For strict expiration, check in application code. TTL deletion doesn’t consume write capacity (free).

Issue 1: Queries Return No Results Check: (1) Partition key value correct? (2) Table has items? (Click Explore → Scan all → see any items?). (3) Querying correct index? (4) Filters too restrictive? Solution: use Scan (no filters) to verify items exist.

Issue 2: “ProvisionedThroughputExceededException” Error Cause: requests exceed provisioned capacity. Solution: (1) Check Monitoring tab → ConsumedReadCapacityUnits/ConsumedWriteCapacityUnits exceeding provisioned? (2) Increase capacity in Capacity tab. (3) Or switch to on-demand mode.

Issue 3: High Latency (Slow Queries) Check: (1) Monitoring tab → Latency metric. (2) Hot partition? (use CloudWatch to see distribution). (3) Query inefficient (scanning instead of querying)? Solution: check query conditions, add GSI if needed, optimize partition key.

Issue 4: Can’t Create Table Check: (1) Table name already exists? (must be unique). (2) Partition key valid? (3) Quota limits? (100 tables per account default). Solution: delete unused table, contact AWS support for quota increase.

Issue 5: “ValidationException” When Creating Item Check: (1) Partition key missing? (required). (2) Data type mismatch? (expected String, got Number?). (3) Attribute name invalid? Solution: re-enter carefully, check data types.
