AWS DynamoDB Query

AWS DynamoDB Query

Certified

Query DynamoDB items by key condition

Executes a Query and follows LastEvaluatedKey until every matching item is read. fetchType defaults to STORE, writing results to internal storage; FETCH and FETCH_ONE load results into memory. Optional limit stops once that many matching items are collected.

Query items from a table

yaml
id: aws_dynamo_db_query
namespace: company.team

tasks:
  - id: query
    type: io.kestra.plugin.aws.dynamodb.Query
    accessKeyId: "{{ secret('AWS_ACCESS_KEY_ID') }}"
    secretKeyId: "{{ secret('AWS_SECRET_KEY_ID') }}"
    region: "eu-central-1"
    tableName: "persons"
    keyConditionExpression: id = :id

      :id: "1"

Query items from a table with a filter expression

Properties

Expression attribute values

Map of placeholders used in expressions.

Key condition expression

Expression using partition key (and sort key if defined).

Table name

Target DynamoDB table for the operation.

Access Key Id in order to connect to AWS

If no credentials are defined, we will use the default credentials provider chain to fetch credentials.

Assets this task consumes as inputs or produces as outputs, for lineage tracking and the asset graph (Enterprise Edition). A flow declaring this property on a task is rejected in the open-source edition.

Definitions
assetFailureBehaviorstring
Possible Values
IGNOREFAILWARN

Asset failure behavior

Behavior applied to the task state when a declared asset fails to render, emit, or be persisted (e.g. a lock conflict): FAIL escalates it to FAILED, WARN (default) warns it if it would otherwise succeed, IGNORE leaves the state untouched.

enableAutobooleanstring

Whether to auto-register assets referenced dynamically at runtime that are not statically declared in inputs or outputs.

inputsarray

The assets consumed as inputs.

The endpoint with which the SDK should communicate

This property allows you to use a different S3 compatible storage backend.

DefaultSTORE
Possible Values
STOREFETCHFETCH_ONENONE

Fetch strategy

STORE (default) writes rows to internal storage; FETCH loads all rows; FETCH_ONE returns the first row.

Filter expression

Additional server-side filter; requires expressionAttributeValues.

Max results

Maximum number of matching items to return across pages. Minimum 1 when set. Leave empty to return every match. This is not a DynamoDB page size.

AWS region with which the SDK should communicate

Secret Key Id in order to connect to AWS

If no credentials are defined, we will use the default credentials provider chain to fetch credentials.

AWS session token, retrieved from an AWS token service, used for authenticating that this user has received temporary permissions to access a given resource

If no credentials are defined, we will use the default credentials provider chain to fetch credentials.

The AWS STS endpoint with which the SDKClient should communicate

AWS STS Role

The Amazon Resource Name (ARN) of the role to assume. If set the task will use the StsAssumeRoleCredentialsProvider. If no credentials are defined, we will use the default credentials provider chain to fetch credentials.

AWS STS External Id

A unique identifier that might be required when you assume a role in another account. This property is only used when an stsRoleArn is defined.

DefaultPT15M

AWS STS Session duration

The duration of the role session (default: 15 minutes, i.e., PT15M). This property is only used when an stsRoleArn is defined.

AWS STS Session name

This property is only used when an stsRoleArn is defined.

Map containing the first row of fetched data.

Only populated if using fetchType=FETCH_ONE.

List containing the fetched data.

Only populated if using fetchType=FETCH.

The number of fetched rows.

Formaturi

Kestra's internal storage URI of the stored data.

Only populated if using fetchType=STORE.

Unititems

Number of items fetched from DynamoDB
