Always batch 5,000+ points per write request. + +**Bucket Delete/Recreate with Read Replicas**: Deleting and recreating a bucket on the primary causes replication interruption due to bucket ID mismatch. Avoid this pattern — update the bucket instead. + +**Processing Engine on Multi-Node**: Scheduled triggers execute on EVERY node. On small instances (db.influx.xlarge), this causes OOM (Memory Exhausted while HashAggSpill). Use `node_spec` to target specific nodes, or scale up instance type. + +## Important — Will Cause Confusion + +**Parameter Group Name Must Be Alphanumeric**: The `--name` for `create-db-parameter-group` also only accepts `[a-zA-Z0-9]+` — no hyphens or underscores. Use the parameter group **ID** (not name) in `--db-parameter-group-identifier` when creating instances/clusters. + +**No IAM on Data Plane**: Control plane uses SigV4/IAM. Data plane uses engine-level Bearer tokens only. IAM ReadOnly policy does NOT restrict data plane access. IAM integration for V3 data plane is planned but not yet available. + +**Flux Not Supported in V3**: Users migrating from V2 must rewrite all Flux queries to SQL or InfluxQL. There is no automatic migration tool. + +**UpdateDbParameterGroup Not Available**: The AWS SDK does not expose this operation. To change parameters, create a new parameter group and update the instance/cluster to reference it. + +**No Direct Host Access**: Cannot SSH into instances.

Siemens hit this. Increasing beyond recommendation requires understanding compaction and query performance implications. + +**S3 Endpoint for Private V3**: Private V3 instances require an S3 VPC endpoint in the same account VPC. Without it, writes fail silently or timeout. + +**Compactor Node OOM**: In V3 Enterprise, uneven load distribution can cause compactor nodes to OOM. Monitor `system.parquet_files` for growing file counts. Consider dedicated compactor nodes. + +**IO Threads Default**: V3 default is 2 IO threads (`--num-io-threads`). Often insufficient for production workloads. Tune via parameter group. + +## Cost — Will Cause Bill Shock + +**V3 License Fee**: Both Core and Enterprise add a per-vCPU license fee via AWS Marketplace (InfluxData). This is separate from the AWS instance cost.

If you need 7-day and 90-day retention, create two buckets. + +Common patterns: + +| Pattern | Buckets | Use case | +|---------|---------|----------| +| By retention | `raw-7d`, `downsampled-90d`, `archive-365d` | Different data lifetimes | +| By environment | `metrics-prod`, `metrics-staging` | Isolation + different retention | +| By team/tenant | `team-a-metrics`, `team-b-metrics` | Access control via scoped tokens | + +Guidance: +- The initial bucket is created automatically by `create-db-instance` — use it for your primary workload. +- Create additional buckets via `POST /api/v2/buckets` for different retention needs. +- Scope tokens to specific buckets for access control — one token per bucket per application. +- Do **not** create a bucket per measurement or per host — this creates management overhead with no benefit. +- On Timestream for InfluxDB V2, **do not delete and recreate buckets** when using read replicas — the bucket ID mismatch breaks replication. Update the bucket instead. + +### Bucket creation example + +```bash +curl -X POST "https://:8086/api/v2/buckets" \ + -H "Authorization: Token $TOKEN" \ + -H "Content-Type: application/json" \ + -d '{ + "name": "downsampled-90d", + "orgID": "", + "retentionRules": [{ "type": "expire", "everySeconds": 7776000 }], + "description": "90-day downsampled metrics" + }' +``` + +## Retention Policy + +Retention is configured per bucket via `retentionRules[].everySeconds`. The retention enforcement service runs every 30 minutes by default and deletes entire shard groups (not individual points) when the shard group's time range is fully beyond the retention period. + +Common retention values: + +| Duration | `everySeconds` | Use case | +|----------|---------------|----------| +| 1 hour | `3600` | Debugging / ephemeral data | +| 1 day | `86400` | Short-term operational metrics | +| 7 days | `604800` | Standard monitoring | +| 30 days | `2592000` | Default for most workloads | +| 90 days | `7776000` | Compliance / trend analysis | +| 1 year | `31536000` | Long-term capacity planning | +| Infinite | `0` | Never expire (use with caution — disk fills) | + +When data is actually deleted: +- **Minimum**: after `retention-period` has elapsed +- **Maximum**: after `retention-period + shard-group-duration` has elapsed +- Shard group duration is auto-calculated from retention period. For a 7-day retention, shard group duration is typically 1 day, so data persists 7–8 days. +- Data remains queryable until the shard group is deleted. + +Retention can be updated on an existing bucket via `PATCH /api/v2/buckets/{bucketID}`: + +```bash +curl -X PATCH "https://:8086/api/v2/buckets/" \ + -H "Authorization: Token $TOKEN" \ + -H "Content-Type: application/json" \ + -d '{ "retentionRules": [{ "type": "expire", "everySeconds": 604800 }] }' +``` + +### Downsampling pattern + +Use a Flux task to aggregate raw data into a longer-retention bucket: + +1. Create `raw-7d` bucket (7-day retention) for high-resolution data +2. Create `downsampled-90d` bucket (90-day retention) for aggregated data +3. Schedule a task to downsample hourly: + +```flux +option task = {name: "downsample-cpu", every: 1h} + +from(bucket: "raw-7d") + |> range(start: -task.every) + |> filter(fn: (r) => r._measurement == "cpu") + |> aggregateWindow(every: 5m, fn: mean, createEmpty: false) + |> to(bucket: "downsampled-90d") +``` + +## Field Type Conflicts + +Field types are **locked on first write** per measurement per field key on both V2 and V3. Writing a different type to the same field causes an error and the conflicting points are dropped. + +| First write | Subsequent write | Result | +|-------------|-----------------|--------| +| `temp=72.3` (float) | `temp=72i` (integer) | Error — `temp` is locked as float | +| `count=10i` (integer) | `count=10.0` (float) | Error — `count` is locked as integer | +| `status="ok"` (string) | `status=true` (boolean) | Error — `status` is locked as string | + +InfluxDB v2 returns **422**. Conflicting points are dropped; valid points in the same batch succeed (partial write). + +Prevention: +- Document your schema before writing. Agree on types per field across all writers. +- Use explicit type suffixes in line protocol: `i` for integer, `"quotes"` for string, bare number for float. +- Be careful with numeric fields — `10` is a float, `10i` is an integer. Mixing these is the most common conflict. +- Telegraf plugins have fixed output types — check plugin docs before adding new inputs. + +Detection: use `SHOW FIELD KEYS FROM ` (InfluxQL) to check current field types. + +Resolution: +- You **cannot change** a field's type after first write. Options: + 1. Write to a new field name (e.g., `temp_f` instead of `temp`) and update queries. + 2. Delete all data in the measurement and rewrite with the correct type. + 3. Create a new measurement with the correct schema and migrate data via a task. + +## Series Cardinality + +A **series** is a unique combination of measurement name + tag set. Series cardinality = total number of unique series across all measurements. + +Example: `cpu,host=A,region=us` and `cpu,host=B,region=us` are 2 series. + +V2 TSM engine: performance typically degrades above **~10M series**, depending on instance size and workload.

Ingestion, querying, compaction, and the processing engine all run on one node and share compute. Core has **no dedicated compactor**, so it is best for recent data (typically the last 3–5 days). +- **Enterprise** (`InfluxDBV3Enterprise`) — a **multi-node** cluster, up to 15 nodes: 1–4 writer (ingest) nodes, 0–13 read-only (query) nodes, and 1 compactor node. Nodes can be assigned distinct roles to isolate ingest/query/compaction/processing. All multi-node deployments are spread across multiple AZs for availability. + +**Summary:** V2 is single-node unless you build a read-replica cluster; V3 is only ever a cluster (single-node for Core, multi-node for Enterprise). + +## Architecture & Storage + +**V2** uses the InfluxDB 2.x **TSM** storage engine with a **TSI** (time-series index). Tags are indexed, which is what makes high cardinality expensive — every unique tag-value combination becomes a series key, and large indexes drive memory pressure and slow writes/queries. Practical guidance caps a V2 instance at **~10M series**. Storage is local **Influx IOPS Included** block volumes (up to 16 TiB), and **storage cannot be increased after creation** — capacity must be planned upfront. + +**V3** is a ground-up redesign built on open formats: +- **Rust** core for performance. +- **Apache Arrow** for in-memory columnar processing (vectorized execution, predicate/projection pushdown). +- **Apache Parquet** for persisted columnar files. +- **Apache DataFusion** as the query optimizer/engine. +- **Apache Arrow Flight SQL** (gRPC) as the high-performance query protocol. +- **Amazon S3** as the core storage layer — 11 nines (99.999999999%) durability, multi-AZ, and effectively elastic capacity. + +V3 also adds two in-memory caches that accelerate common patterns: +- **Last Value Cache (LVC)** — most recent value per field; millisecond "last point" lookups for dashboards. +- **Distinct Value Cache (DVC)** — unique tag/field values per table; fast metadata queries (e.g., listing host or sensor IDs). + +## Query Languages + +- **V2:** **Flux** is the primary language; **InfluxQL** is also supported, **SQL** is not. +- **V3:** **SQL** is the primary language (via DataFusion); a v1-compatible **InfluxQL** endpoint is provided for legacy apps. **Flux is not supported.** + +There is **no automatic Flux-to-SQL conversion**. Migrating from V2 to V3 requires rewriting all Flux queries, tasks, and dashboards into SQL or InfluxQL. + +## Data Model & API + +- **V2** organizes data as **Organization → Bucket**. Writes specify `org` and `bucket`; data-plane auth uses the `Token` prefix; default port **8086**. +- **V3** organizes data as **Database → Table** (no organizations). Tables are created automatically on first write (a measurement becomes a table). Writes specify `db`; data-plane auth uses the `Bearer` prefix; default port **8181**. + +**Backward compatibility:** V3 exposes v1- and v2-compatible write endpoints (including `/api/v2/write`), so existing line-protocol writers and Telegraf configs can keep writing without changes during a migration. Line protocol itself is unchanged across versions. + +## Automation / Processing + +- **V2** uses **Tasks** — scheduled Flux scripts for downsampling, alerting, and transforms. +- **V3** ships a **processing engine**: an embedded Python virtual machine that runs plugins on scheduled events or WAL-flush events (downsampling, alerting, anomaly detection) with zero-copy access to data. Timestream for InfluxDB 3 provides a curated, security-hardened set of plugins. + - **Gotcha:** on multi-node Enterprise, scheduled triggers run on **every** node and can OOM small instances — target nodes with `node_spec` or scale up. + +## Cost & Licensing + +- **V2:** billed on instance hours + provisioned storage (per GiB) + data transfer. **Read replicas add a license fee**. +- **V3 Core:** compute + S3 storage only — **no license fee**. +- **V3 Enterprise:** compute + S3 storage **plus** an Enterprise license billed per node-hour via **AWS Marketplace** (InfluxData). The license is separate from AWS compute spend, and **EDP discounts do not apply** to Marketplace charges. + +## Choosing / Migration Guidance + +- **Choose V3** for high or unpredictable cardinality, SQL/BI integration, large historical retention (cheap S3), or when you need a multi-node solution for high ingest. V3 is also the forward path for workloads leaving Timestream for LiveAnalytics (in maintenance mode). +- **Stay on / choose V2** when you depend on **Flux**, existing v2 tooling/dashboards, or org/bucket semantics, and your cardinality stays well under ~10M series. +- **Migration checklist (V2 → V3):** rewrite Flux → SQL/InfluxQL; map orgs/buckets → databases/tables; switch auth `Token` → `Bearer` and port `8086` → `8181`; re-point writers (or use V3's v2-compatible write endpoint); re-provision as a cluster (Core or Enterprise). +- **No turnkey data migration:** the engines share no storage format, and managed V2 blocks host access (so the OSS `influxd inspect export-lp` disk dump is unavailable). Data must move through the **query API**: extract from V2 as annotated CSV or a DataFrame (V2 cannot emit line protocol from queries), then load into V3 — the InfluxDB 3 Python client's `write_file()` (CSV/JSON/Parquet/…) and `write_dataframe()` are the most capable loaders. Full runbook: `influxdb2/migrations.md`. + +## Retrieving tokens + +To interact with your deployed Timestream for InfluxDB instance or cluster, creating buckets, executing queries, ingesting data, etc., using the InfluxDB v2 or v3 HTTP APIs, you must retrieve or create an InfluxDB token. + +### V2 + +Once your v2 instance or cluster has been deployed, create a new operator token, using the [Influx v2 CLI](https://docs.influxdata.com/influxdb/v2/tools/influx-cli/?section=influxdb%252Fv2%252Ftools): + +```shell +influx config create --config-name CONFIG_NAME1 --host-url "https://yourinstanceid.eu-central-1.timestream-influxdb.amazonaws.com:8086" --org [YOURORG] --username-password [YOURUSERNAME] --active + +influx auth create --org [YOURORG] --operator +``` + +### V3 + +After you have deployed a Timestream for InfluxDB v3 cluster, a secret in AWS Secrets Manager will be associated with your cluster.

Without it, writes fail silently or timeout. - **Compactor Node OOM**: In V3 Enterprise, uneven load distribution can cause compactor nodes to OOM. Monitor `system.parquet_files` for growing file counts. Consider dedicated compactor nodes. **IO Threads Default**: V3 default is 2 IO threads (`--num-io-threads`). Often insufficient for production workloads.

Migration is a manual **extract → transform → load (ETL)** of the data itself. - -### Why the OSS disk-export path does NOT work here -On open-source InfluxDB you would normally run `influxd inspect export-lp` to dump TSM files directly to line protocol. **This is unavailable on Timestream for InfluxDB** — the managed service does not allow host/SSH/filesystem access (see `influxdb2/gotchas.md`). All data must leave V2 through the **query API**. - -### The line-protocol catch -Both V2 and V3 *accept* line protocol on write, so line protocol seems like the obvious interchange format. The problem: **V2 cannot emit query results as line protocol.** A V2 Flux/InfluxQL query returns **annotated CSV** (or, via a client library, a DataFrame) — never line protocol. So a migration must either: -1. Convert the exported CSV/DataFrame to line protocol yourself before writing to V3, or -2. Skip line protocol entirely and load the CSV/DataFrame straight into V3. - -Option 2 is simpler and is what the InfluxDB 3 Python client is built for. - -### Extract from V2 -- **Annotated CSV** — `influx query --raw 'from(bucket:"b") |> range(start: ...)'` or the HTTP `/api/v2/query` endpoint. Native, no extra deps, but you own the CSV→target mapping. -- **DataFrame (recommended)** — the V2 Python client (`influxdb-client`) returns pandas directly: - ```python - from influxdb_client import InfluxDBClient - with InfluxDBClient(url=V2_URL, token=V2_TOKEN, org=V2_ORG) as v2: - df = v2.query_api().query_data_frame( - 'from(bucket:"my-bucket") |> range(start: -30d)') - ``` - Pull in **time-bounded chunks** (e.g. day-by-day) so you never hold a whole bucket in memory. - -### Load into V3 -The InfluxDB 3 Python client (`influxdb3-python`, module `influxdb_client_3`) has the richest file/DataFrame ingestion and is the preferred loader: -- **`write_file()`** imports **CSV, JSON, Feather, ORC, or Parquet** directly — best for offline/bulk migrations where V2 data was first dumped to files. - ```python - client.write_file(file="./export.csv", - timestamp_column="time", tag_columns=["host", "region"]) - ``` -- **`write_dataframe()`** writes a pandas/polars DataFrame straight through — pairs directly with the V2 `query_data_frame()` extract above (no intermediate file). - ```python - client.write_dataframe(df, measurement="cpu", - timestamp_column="time", tags=["host", "region"]) - ``` -- **Line protocol / `write()`** also works if you generated LP yourself, including via V3's v1/v2-compatible write endpoints (`/api/v2/write`) so existing V2 writers can be re-pointed unchanged. - -### Recommended end-to-end pattern -Python bridge, chunked by time range: `v2.query_data_frame(range)` → `v3.write_dataframe(df, ...)`. No files, no manual line-protocol generation, and `pandas` is the only extra dependency. Use files (CSV/Parquet via `write_file`) instead when the export and import happen on different machines or you need a durable intermediate copy. - -### Things to get right during migration -- **Namespace mapping:** V2 `org`/`bucket` → V3 `database`; each V2 `measurement` → a V3 `table`. -- **Tags vs. fields:** preserve which columns are tags (`tag_columns`/`tags`) vs. fields — this defines the V3 schema on first write. -- **Batching:** write **5,000+ points per request**; many tiny writes cause replica lag (see `gotchas.md`). -- **Timestamp precision:** carry the original precision (ns by default); a wrong precision silently shifts every point. -- **Historical backfill:** iterate over time windows oldest→newest; size windows to instance memory. -- **Queries/apps, not just data:** there is no Flux in V3. Rewrite all Flux queries, tasks, and dashboards to **SQL or InfluxQL** before cutover. The processing engine (Python plugins) replaces V2 Flux tasks for downsampling/alerting. - -### Validate -After loading, compare per-table row counts and cardinality between source and target, and spot-check a few time ranges (`SELECT count(*)`, min/max timestamps, sample rows) before decommissioning the V2 instance. +# Migrating to Timestream for InfluxDB v2 + +How to migrate **into** Timestream for InfluxDB v2 from common +sources.
