SeaweedFS supports the S3 Tables API, providing a way to manage table-based data structures with AWS S3 compatibility. This guide provides commands to test the S3 Tables features in SeaweedFS.

Configuration

Prerequisites

For AWS CLI and curl commands, configure your environment variables:

export S3_ENDPOINT=http://localhost:8333
export AWS_ACCESS_KEY_ID=any
export AWS_SECRET_ACCESS_KEY=any
export AWS_DEFAULT_REGION=us-east-1

Note

The s3tables service is a relatively new AWS service. Ensure your AWS CLI is up to date (v2.17+ recommended). If aws s3tables is not available, use the curl commands provided below.

1. Table Bucket Operations

Create Table Bucket

AWS CLI:

aws s3tables create-table-bucket --endpoint-url $S3_ENDPOINT --name my-test-bucket

curl:

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.CreateTableBucket" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{"name": "my-test-bucket"}'

Note

A table bucket holds one table format. format is a SeaweedFS extension to CreateTableBucket and accepts ICEBERG (the default, and what AWS S3 Tables serves) or LANCE. Creating a table of another format in a declared bucket is refused with 409.

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.CreateTableBucket" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{"name": "vectors", "format": "LANCE"}'

From the shell: s3tables.bucket -create -name vectors -format LANCE -account 000000000000

At startup: weed mini -tableBucket=vectors:LANCE pre-creates buckets before anything connects, each entry name[:FORMAT] with an unsuffixed name meaning ICEBERG. The same list can come from S3_TABLE_BUCKET.

Buckets created before this field existed carry no declaration and keep accepting either format. See SeaweedFS Lance Catalog.

---

List Table Buckets

AWS CLI:

aws s3tables list-table-buckets --endpoint-url $S3_ENDPOINT

curl:

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.ListTableBuckets" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{}'

---

Get Table Bucket

AWS CLI:

aws s3tables get-table-bucket --endpoint-url $S3_ENDPOINT --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket

curl:

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.GetTableBucket" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{"tableBucketARN": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket"}'

---

2. Namespace Operations

curl:

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.CreateNamespace" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{
    "tableBucketARN": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket",
    "namespace": ["my_namespace"]
  }'

---

List Namespaces

AWS CLI:

aws s3tables list-namespaces --endpoint-url $S3_ENDPOINT --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket

  -H "X-Amz-Target: S3Tables.ListNamespaces" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{"tableBucketARN": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket"}'

---

3. Table Operations

  }'

---

4. Policy and Tagging

Put Table Bucket Policy

AWS CLI:

aws s3tables put-table-bucket-policy --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket \
  --resource-policy "{\"Version\":\"2012-10-17\",\"Statement\":[{\"Effect\":\"Allow\",\"Principal\":\"*\",\"Action\":\"s3tables:*\",\"Resource\":\"*\"}]}"

curl:

  -H "X-Amz-Target: S3Tables.PutTableBucketPolicy" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{
    "tableBucketARN": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket",
    "resourcePolicy": "{\"Version\":\"2012-10-17\",\"Statement\":[{\"Effect\":\"Allow\",\"Principal\":\"*\",\"Action\":\"s3tables:*\",\"Resource\":\"*\"}]}"
  }'

Get Table Bucket Policy

AWS CLI:

aws s3tables get-table-bucket-policy --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket

curl:

  -H "X-Amz-Target: S3Tables.GetTableBucketPolicy" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{"tableBucketARN": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket"}'

Tag Resource

AWS CLI:

aws s3tables tag-resource --endpoint-url $S3_ENDPOINT \
  --resource-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket \
  --tags Environment=test,Owner=admin

curl:

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.TagResource" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{
    "resourceArn": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket",
    "tags": {"Environment": "test", "Owner": "admin"}
  }'

List Tags

  --resource-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket

curl:

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.ListTagsForResource" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{"resourceArn": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket"}'

5. Maintenance Configuration

Compaction and snapshot management are configured per table; unreferenced file removal is configured on the table bucket. See Iceberg Table Maintenance for what the worker does with these settings, and for the table properties that take precedence over them.

Put Table Maintenance Configuration

AWS CLI:

aws s3tables put-table-maintenance-configuration --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket \
  --namespace my_namespace \
  --name my_table \
  --type icebergCompaction \
  --value '{"status":"enabled","settings":{"icebergCompaction":{"targetFileSizeMB":512,"strategy":"auto"}}}'

curl:

curl -X PUT "$S3_ENDPOINT/tables/arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket/my_namespace/my_table/maintenance/icebergCompaction" \
  -H "Content-Type: application/json" \
  -d '{
    "value": {
      "status": "enabled",
      "settings": {"icebergCompaction": {"targetFileSizeMB": 512, "strategy": "auto"}}
    }
  }'

Turn a maintenance type off for a table:

aws s3tables put-table-maintenance-configuration --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket \
  --namespace my_namespace \
  --name my_table \
  --type icebergSnapshotManagement \
  --value '{"status":"disabled"}'

Get Table Maintenance Configuration

AWS CLI:

aws s3tables get-table-maintenance-configuration --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket \
  --namespace my_namespace \
  --name my_table

A table that has never been configured returns an empty configuration; the effective values then come from the worker config.

Get Table Maintenance Job Status

AWS CLI:

aws s3tables get-table-maintenance-job-status --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket \
  --namespace my_namespace \
  --name my_table

Each job type reports Not_Yet_Run, Successful, Failed or Disabled, with the time of the last run.

Put Table Bucket Maintenance Configuration

AWS CLI:

aws s3tables put-table-bucket-maintenance-configuration --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket \
  --type icebergUnreferencedFileRemoval \
  --value '{"status":"enabled","settings":{"icebergUnreferencedFileRemoval":{"unreferencedDays":3,"nonCurrentDays":10}}}'

A file is deleted once it is older than unreferencedDays plus nonCurrentDays — thirteen days here.

Get Table Bucket Maintenance Configuration

AWS CLI:

aws s3tables get-table-bucket-maintenance-configuration --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket

---

Cleanup

Delete Table

AWS CLI:

aws s3tables delete-table --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket \
  --namespace my_namespace \
  --name my_table

curl:

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.DeleteTable" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{
    "tableBucketARN": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket",
    "namespace": ["my_namespace"],
    "name": "my_table"
  }'

Delete Namespace

AWS CLI:

aws s3tables delete-namespace --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket \
  --namespace my_namespace

curl:

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.DeleteNamespace" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{
    "tableBucketARN": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket",
    "namespace": ["my_namespace"]
  }'

Delete Table Bucket

AWS CLI:

aws s3tables delete-table-bucket --endpoint-url $S3_ENDPOINT \
  --table-bucket-arn arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket

curl:

curl -X POST $S3_ENDPOINT/ \
  -H "X-Amz-Target: S3Tables.DeleteTableBucket" \
  -H "Content-Type: application/x-amz-json-1.1" \
  -d '{"tableBucketARN": "arn:aws:s3tables:us-east-1:000000000000:bucket/my-test-bucket"}'
