+---
+
+import PangolinCloudTocCta from "/snippets/pangolin-cloud-toc-cta.mdx";
+
+
+
+S3 destinations upload batches of your organization's audit logs as objects in a bucket you control. Use them for long-term archival, data lakes (Athena, Glue, BigQuery), or S3-compatible stores such as MinIO and Cloudflare R2.
+
+
+Event streaming is only available in [Pangolin Cloud](https://app.pangolin.net/auth/signup) or self-hosted [Enterprise Edition](/self-host/enterprise-edition).
+
+
+## Overview
+
+An S3 destination writes **one object per batch** via `PutObject`. Each object contains up to 250 events of a **single log type**. There is no custom body template or field mapping; Pangolin serializes every event in a fixed shape and chooses the object key automatically.
+
+Configure:
+
+1. **Settings:** Name, credentials, region, bucket, optional prefix and custom endpoint.
+2. **Format:** File format (JSON array, NDJSON, or CSV) and optional gzip compression.
+3. **Logs:** Which log types are forwarded.
+
+## Settings tab
+
+| Field | Required | Description |
+| --- | --- | --- |
+| Name | Yes | Display label for this destination |
+| AWS Access Key ID | Yes | Static access key for the S3 client |
+| AWS Secret Access Key | Yes | Secret for the access key |
+| AWS Region | Yes | S3 client region (UI default: `us-east-1`) |
+| Bucket name | Yes | Target bucket |
+| Key prefix | No | Prepended to every object key; trailing slashes are stripped |
+| Custom endpoint | No | Base URL for MinIO, R2, etc.; leave blank for AWS S3 |
+
+Pangolin uses static access keys only. There is no IAM role, instance profile, or OIDC picker in the UI.
+
+
+
+
+
+Uploads time out after 60 seconds per object.
+
+## Format tab
+
+**Gzip compression** (optional): When enabled, the object body is gzip-compressed before upload, `Content-Encoding: gzip` is set, and the object key gets a `.gz` suffix (for example `….json.gz`). Decompress before parsing unless your tool handles gzip automatically.
+
+**File format:**
+
+| Format | Description |
+| --- | --- |
+| **JSON array** (default) | One array per object: `[{…}, {…}, …]` |
+| **NDJSON** | One JSON object per line, no outer array |
+| **CSV** | RFC-4180 CSV with a header row; see [CSV format](#csv-format) |
+
+
+
+
+
+## Logs tab
+
+Choose which log categories are uploaded. Each enabled type is written to its own key prefix (`request/`, `action/`, etc.). Only log types enabled for your organization can be streamed.
+
+
+
+
+
+## Object key layout
+
+Every upload gets a unique key:
+
+```
+{prefix}/{logType}/{YYYY}/{MM}/{DD}/{HH-mm-ss-uuid}.{ext}[.gz]
+```
+
+| Segment | Meaning |
+| --- | --- |
+| `prefix` | Your optional key prefix; omitted when empty |
+| `logType` | `request`, `action`, `access`, or `connection` |
+| `YYYY/MM/DD` | **Upload time (UTC)**, not the event timestamp |
+| `HH-mm-ss-uuid` | Upload time plus a UUID so keys never collide |
+| `ext` | `json` (JSON array), `ndjson`, or `csv` |
+| `.gz` | Present when gzip is enabled |
+
+**Without prefix:**
+
+```
+request/2026/06/04/14-30-45-a1b2c3d4-e5f6-7890-abcd-ef1234567890.json
+```
+
+**With prefix `pangolin/audit` and gzip:**
+
+```
+pangolin/audit/action/2026/06/04/14-30-45-a1b2c3d4-e5f6-7890-abcd-ef1234567890.json.gz
+```
+
+Enabling multiple log types on one destination produces **separate object streams** under different `logType/` segments. A single object never mixes log types.
+
+## Event record shape
+
+Each event in JSON and NDJSON objects uses this fixed structure:
+
+```json
+{
+ "event": "request",
+ "timestamp": "2026-06-04T12:00:00.000Z",
+ "data": {
+ "timestamp": 1717492800,
+ "action": true,
+ "method": "GET",
+ "path": "/api/health"
+ }
+}
+```
+
+| Field | Meaning |
+| --- | --- |
+| `event` | Log type: `request`, `access`, `action`, or `connection` |
+| `timestamp` | Event time as ISO-8601 UTC (connection logs use session start) |
+| `data` | The **complete stored log row** for that record, not a curated subset |
+
+
+Some columns are stored as JSON strings in the database (`headers`, `query`, and `metadata` on request logs, for example). In `data`, they appear as **string values**, not nested JSON objects. Parse them in your pipeline if you need structured fields.
+
+
+## File formats
+
+### JSON array (default)
+
+- One S3 object per batch; body is `[{…}, {…}, …]`.
+- Up to 250 events per object.
+- `Content-Type: application/json`.
+
+### NDJSON
+
+- One S3 object per batch; body is one JSON record per line with no outer array.
+- Good for Athena, BigQuery load jobs, Spark, and similar line-oriented pipelines.
+- `Content-Type: application/x-ndjson`.
+
+### CSV format
+
+- Header row: `event`, `timestamp`, then **all field names** found in `data` across that batch (union of keys, in insertion order).
+- Each data row flattens `event`, `timestamp`, and spreads `data` fields into columns. There is **no** nested `data` column.
+- Missing fields in a given row leave an empty cell.
+- Object or array values in `data` are written as `JSON.stringify` strings inside the cell.
+- `Content-Type: text/csv; charset=utf-8`.
+
+The column set can grow as new fields appear in later batches. Order is not guaranteed to stay identical across all objects over time.
+
+## Batching and throughput
+
+- Objects are written **per batch** (up to ~250 events), not one object per log line.
+- Pangolin polls for new logs on a regular interval and may write multiple objects during catch-up after a pause.
+- **No backfill:** New destinations start from the current log cursor. Historical logs already in Pangolin are not uploaded.
+- **Extended outage:** If the destination is unreachable for about 24 hours, the backlog may be discarded and streaming resumes from the present cursor (same behavior as [HTTP streaming](/manage/analytics/streaming/http)).
+
+## Gzip
+
+When gzip is enabled:
+
+1. The serialized body is compressed before upload.
+2. The object key includes `.gz` (for example `….ndjson.gz`).
+3. S3 stores `Content-Encoding: gzip`.
+
+Consumers must decompress before parsing unless the tool auto-detects gzip (many Athena and Spark setups do when `Content-Encoding` is set). NDJSON plus gzip is a common choice for cost-sensitive archival.
+
+## S3-compatible storage
+
+Set **Custom endpoint** to your vendor's S3 API URL and provide access key credentials per that vendor's documentation.
+
+| Store | Notes |
+| --- | --- |
+| **AWS S3** | Leave custom endpoint blank; use a bucket in the configured region |
+| **MinIO** | Set endpoint to your MinIO server URL; use MinIO access keys |
+| **Cloudflare R2** | Set endpoint to your R2 S3 API URL; use R2 access keys |
+
+Pangolin does not expose path-style vs virtual-hosted addressing, ACLs, SSE-KMS, storage class, or multipart tuning. Configure those in the vendor console or bucket policy.
+
+## IAM and bucket policy
+
+Grant the access key permission to write under your prefix. A minimal AWS example:
+
+```json
+{
+ "Version": "2012-10-17",
+ "Statement": [
+ {
+ "Effect": "Allow",
+ "Action": ["s3:PutObject"],
+ "Resource": "arn:aws:s3:::your-bucket/pangolin/audit/*"
+ },
+ {
+ "Effect": "Allow",
+ "Action": ["s3:ListBucket"],
+ "Resource": "arn:aws:s3:::your-bucket",
+ "Condition": {
+ "StringLike": { "s3:prefix": ["pangolin/audit/*"] }
+ }
+ }
+ ]
+}
+```
+
+Adjust bucket name and prefix to match your configuration. `ListBucket` is optional but useful when debugging missing objects.
+
+Block public access, encryption at rest, lifecycle rules, and object tags are configured in AWS or your vendor console, not in Pangolin.
+
+## Log type reference
+
+The `data` object in each streamed event is the full stored log row. Field sets differ by log type. See the documentation for that log type under **Logs & Analytics** for the complete `data` shape.
+
+## Limitations and troubleshooting
+
+- **No custom JSON shape:** Fixed event record only. Use an HTTP destination if you need body templates or field remapping.
+- **No per-event objects:** Always batched (up to ~250 events per object).
+- **No mixed log types in one object:** Each upload contains a single log type.
+- **Upload-time partitioning:** Key date folders use upload time (UTC), not the event's `timestamp`.
+- **CSV columns:** Automatic from batch contents; not user-selectable; column set may change over time.
+- **Static credentials only:** Rotate keys by updating the destination; credentials are stored encrypted server-side.
+- **Historical logs:** New destinations do not backfill.
+- **Delivery errors:** Check the destination's **last error** in the dashboard. Common causes: `AccessDenied`, wrong bucket or region, bad endpoint URL, TLS issues, or expired credentials.
+- **Missing objects:** Confirm prefix, lifecycle rules, and that the log type is enabled on the **Logs** tab.
+- **Athena/Glue parse errors:** Verify format (JSON array vs NDJSON), gzip handling, and that the crawler/table schema matches flattened CSV columns if using CSV.
