Amazon Timestream Query 2018-11-01
- Client: Aws\TimestreamQuery\TimestreamQueryClient
- Service ID: timestream-query
- Version: 2018-11-01
This page describes the parameters and results for the operations of the Amazon Timestream Query (2018-11-01), and shows how to use the Aws\TimestreamQuery\TimestreamQueryClient object to call the described operations. This documentation is specific to the 2018-11-01 API version of the service.
Operation Summary
Each of the following operations can be created from a client using
$client->getCommand('CommandName')
, where "CommandName" is the
name of one of the following operations. Note: a command is a value that
encapsulates an operation and the parameters used to create an HTTP request.
You can also create and send a command immediately using the magic methods
available on a client object: $client->commandName(/* parameters */)
.
You can send the command asynchronously (returning a promise) by appending the
word "Async" to the operation name: $client->commandNameAsync(/* parameters */)
.

You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:
Operations
CancelQuery
$result = $client->cancelQuery
([/* ... */]); $promise = $client->cancelQueryAsync
([/* ... */]);
Cancels a query that has been issued. Cancellation is provided only if the query has not completed running before the cancellation request was issued. Because cancellation is an idempotent operation, subsequent cancellation requests will return a CancellationMessage
, indicating that the query has already been canceled. See code sample for details.
Parameter Syntax
$result = $client->cancelQuery([ 'QueryId' => '<string>', // REQUIRED ]);
Parameter Details
Members
- QueryId
-
- Required: Yes
- Type: string

Parameter Details
Members
- ClientToken
-
- Type: string
Using a ClientToken makes the call to CreateScheduledQuery idempotent, in other words, making the same request repeatedly will produce the same result. Making multiple identical CreateScheduledQuery requests has the same effect as making a single request.
-
If CreateScheduledQuery is called without a
ClientToken
, the Query SDK generates aClientToken
on your behalf. -
After 8 hours, any request with the same
ClientToken
is treated as a new request.
- ErrorReportConfiguration
-
- Required: Yes
- Type: ErrorReportConfiguration structure
Configuration for error reporting. Error reports will be generated when a problem is encountered when writing the query results.
- KmsKeyId
-
- Type: string
The Amazon KMS key used to encrypt the scheduled query resource, at-rest. If the Amazon KMS key is not specified, the scheduled query resource will be encrypted with a Timestream owned Amazon KMS key. To specify a KMS key, use the key ID, key ARN, alias name, or alias ARN. When using an alias name, prefix the name with alias/
If ErrorReportConfiguration uses
SSE_KMS
as encryption type, the same KmsKeyId is used to encrypt the error report at rest. - Name
-
- Required: Yes
- Type: string
Name of the scheduled query.
- NotificationConfiguration
-
- Required: Yes
- Type: NotificationConfiguration structure
Notification configuration for the scheduled query. A notification is sent by Timestream when a query run finishes, when the state is updated or when you delete it.
- QueryString
-
- Required: Yes
- Type: string
The query string to run. Parameter names can be specified in the query string
@
character followed by an identifier. The named Parameter@scheduled_runtime
is reserved and can be used in the query to get the time at which the query is scheduled to run.The timestamp calculated according to the ScheduleConfiguration parameter, will be the value of
@scheduled_runtime
paramater for each query run. For example, consider an instance of a scheduled query executing on 2021-12-01 00:00:00. For this instance, the@scheduled_runtime
parameter is initialized to the timestamp 2021-12-01 00:00:00 when invoking the query. - ScheduleConfiguration

DescribeEndpoints
$result = $client->describeEndpoints
([/* ... */]); $promise = $client->describeEndpointsAsync
([/* ... */]);
DescribeEndpoints returns a list of available endpoints to make Timestream API calls against. This API is available through both Write and Query.
Because the Timestream SDKs are designed to transparently work with the service’s architecture, including the management and mapping of the service endpoints, it is not recommended that you use this API unless:
-
You are using VPC endpoints (Amazon Web Services PrivateLink) with Timestream
-
Your application uses a programming language that does not yet have SDK support
-
You require better control over the client-side implementation
For detailed information on how and when to use and implement DescribeEndpoints, see The Endpoint Discovery Pattern.

Query
$result = $client->query
([/* ... */]); $promise = $client->queryAsync
([/* ... */]);
Query
is a synchronous operation that enables you to run a query against your Amazon Timestream data.
If you enabled QueryInsights
, this API also returns insights and metrics related to the query that you executed. QueryInsights
helps with performance tuning of your query. For more information about QueryInsights
, see Using query insights to optimize queries in Amazon Timestream.
The maximum number of Query
API requests you're allowed to make with QueryInsights
enabled is 1 query per second (QPS). If you exceed this query rate, it might result in throttling.
Query
will time out after 60 seconds. You must update the default timeout in the SDK to support a timeout of 60 seconds. See the code sample for details.
Your query request will fail in the following cases:
-
If you submit a
Query
request with the same client token outside of the 5-minute idempotency window. -
If you submit a
Query
request with the same client token, but change other parameters, within the 5-minute idempotency window. -
If the size of the row (including the query metadata) exceeds 1 MB, then the query will fail with the following error message:
Query aborted as max page response size has been exceeded by the output result row
-
If the IAM principal of the query initiator and the result reader are not the same and/or the query initiator and the result reader do not have the same query string in the query requests, the query will fail with an
Invalid pagination token
error.
Parameter Syntax
$result = $client->query([ 'ClientToken' => '<string>', 'MaxRows' => <integer>, 'NextToken' => '<string>', 'QueryInsights' => [ 'Mode' => 'ENABLED_WITH_RATE_CONTROL|DISABLED', // REQUIRED ], 'QueryString' => '<string>', // REQUIRED ]);
Parameter Details
Members
- ClientToken
-
- Type: string
Unique, case-sensitive string of up to 64 ASCII characters specified when a
Query
request is made. Providing aClientToken
makes the call toQuery
idempotent. This means that running the same query repeatedly will produce the same result. In other words, making multiple identicalQuery
requests has the same effect as making a single request. When usingClientToken
in a query, note the following:-
If the Query API is instantiated without a
ClientToken
, the Query SDK generates aClientToken
on your behalf. -
If the
Query
invocation only contains theClientToken
but does not include aNextToken
, that invocation ofQuery
is assumed to be a new query run. -
If the invocation contains
NextToken
, that particular invocation is assumed to be a subsequent invocation of a prior call to the Query API, and a result set is returned. -
After 4 hours, any request with the same
ClientToken
is treated as a new request.
- MaxRows
-
- Type: int
The total number of rows to be returned in the
Query
output. The initial run ofQuery
with aMaxRows
value specified will return the result set of the query in two cases:-
The size of the result is less than
1MB
. -
The number of rows in the result set is less than the value of
maxRows
.
Otherwise, the initial invocation of
Query
only returns aNextToken
, which can then be used in subsequent calls to fetch the result set. To resume pagination, provide theNextToken
value in the subsequent command.If the row size is large (e.g. a row has many columns), Timestream may return fewer rows to keep the response size from exceeding the 1 MB limit. If
MaxRows
is not provided, Timestream will send the necessary number of rows to meet the 1 MB limit. - NextToken
-
- Type: string
A pagination token used to return a set of results. When the
Query
API is invoked usingNextToken
, that particular invocation is assumed to be a subsequent invocation of a prior call toQuery
, and a result set is returned. However, if theQuery
invocation only contains theClientToken
, that invocation ofQuery
is assumed to be a new query run.Note the following when using NextToken in a query:
-
A pagination token can be used for up to five
Query
invocations, OR for a duration of up to 1 hour – whichever comes first. -
Using the same
NextToken
will return the same set of records. To keep paginating through the result set, you must to use the most recentnextToken
. -
Suppose a
Query
invocation returns twoNextToken
values,TokenA
andTokenB
. IfTokenB
is used in a subsequentQuery
invocation, thenTokenA
is invalidated and cannot be reused. -
To request a previous result set from a query after pagination has begun, you must re-invoke the Query API.
-
The latest
NextToken
should be used to paginate untilnull
is returned, at which point a newNextToken
should be used. -
If the IAM principal of the query initiator and the result reader are not the same and/or the query initiator and the result reader do not have the same query string in the query requests, the query will fail with an
Invalid pagination token
error.

QueryInsights
Description
QueryInsights
is a performance tuning feature that helps you optimize your queries, reducing costs and improving performance. With QueryInsights
, you can assess the pruning efficiency of your queries and identify areas for improvement to enhance query performance. With QueryInsights
, you can also analyze the effectiveness of your queries in terms of temporal and spatial pruning, and identify opportunities to improve performance. Specifically, you can evaluate how well your queries use time-based and partition key-based indexing strategies to optimize data retrieval. To optimize query performance, it's essential that you fine-tune both the temporal and spatial parameters that govern query execution.
The key metrics provided by QueryInsights
are QuerySpatialCoverage
and QueryTemporalRange
. QuerySpatialCoverage
indicates how much of the spatial axis the query scans, with lower values being more efficient. QueryTemporalRange
shows the time range scanned, with narrower ranges being more performant.
Benefits of QueryInsights
The following are the key benefits of using QueryInsights
:
-
Identifying inefficient queries –
QueryInsights
provides information on the time-based and attribute-based pruning of the tables accessed by the query. This information helps you identify the tables that are sub-optimally accessed. -
Optimizing your data model and partitioning – You can use the
QueryInsights
information to access and fine-tune your data model and partitioning strategy. -
Tuning queries –
QueryInsights
highlights opportunities to use indexes more effectively.
The maximum number of Query
API requests you're allowed to make with QueryInsights
enabled is 1 query per second (QPS). If you exceed this query rate, it might result in throttling.
Members
