Struct aws_sdk_timestreamwrite::operation::write_records::builders::WriteRecordsFluentBuilder

pub struct WriteRecordsFluentBuilder { /* private fields */ }

Fluent builder constructing a request to WriteRecords.

Enables you to write your time-series data into Timestream. You can specify a single data point or a batch of data points to be inserted into the system. Timestream offers you a flexible schema that auto detects the column names and data types for your Timestream tables based on the dimension names and data types of the data points you specify when invoking writes into the database.

Timestream supports eventual consistency read semantics. This means that when you query data immediately after writing a batch of data into Timestream, the query results might not reflect the results of a recently completed write operation. The results may also include some stale data. If you repeat the query request after a short time, the results should return the latest data. Service quotas apply.

See code sample for details.

Upserts

You can use the Version parameter in a WriteRecords request to update data points. Timestream tracks a version number with each record. Version defaults to 1 when it's not specified for the record in the request. Timestream updates an existing record’s measure value along with its Version when it receives a write request with a higher Version number for that record. When it receives an update request where the measure value is the same as that of the existing record, Timestream still updates Version, if it is greater than the existing value of Version. You can update a data point as many times as desired, as long as the value of Version continuously increases.

For example, suppose you write a new record without indicating Version in the request. Timestream stores this record, and set Version to 1. Now, suppose you try to update this record with a WriteRecords request of the same record with a different measure value but, like before, do not provide Version. In this case, Timestream will reject this update with a RejectedRecordsException since the updated record’s version is not greater than the existing value of Version.

However, if you were to resend the update request with Version set to 2, Timestream would then succeed in updating the record’s value, and the Version would be set to 2. Next, suppose you sent a WriteRecords request with this same record and an identical measure value, but with Version set to 3. In this case, Timestream would only update Version to 3. Any further updates would need to send a version number greater than 3, or the update requests would receive a RejectedRecordsException.

Implementations

impl WriteRecordsFluentBuilder

pub fn as_input(&self) -> &WriteRecordsInputBuilder

Access the WriteRecords as a reference.

pub async fn send( self ) -> Result<WriteRecordsOutput, SdkError<WriteRecordsError, HttpResponse>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub async fn customize( self ) -> Result<CustomizableOperation<WriteRecordsOutput, WriteRecordsError, Self>, SdkError<WriteRecordsError>>

Consumes this builder, creating a customizable operation that can be modified before being sent.

pub fn database_name(self, input: impl Into<String>) -> Self

The name of the Timestream database.

pub fn set_database_name(self, input: Option<String>) -> Self

The name of the Timestream database.

pub fn get_database_name(&self) -> &Option<String>

The name of the Timestream database.

pub fn table_name(self, input: impl Into<String>) -> Self

The name of the Timestream table.

pub fn set_table_name(self, input: Option<String>) -> Self

The name of the Timestream table.

pub fn get_table_name(&self) -> &Option<String>

The name of the Timestream table.

pub fn common_attributes(self, input: Record) -> Self

A record that contains the common measure, dimension, time, and version attributes shared across all the records in the request. The measure and dimension attributes specified will be merged with the measure and dimension attributes in the records object when the data is written into Timestream. Dimensions may not overlap, or a ValidationException will be thrown. In other words, a record must contain dimensions with unique names.

pub fn set_common_attributes(self, input: Option<Record>) -> Self

A record that contains the common measure, dimension, time, and version attributes shared across all the records in the request. The measure and dimension attributes specified will be merged with the measure and dimension attributes in the records object when the data is written into Timestream. Dimensions may not overlap, or a ValidationException will be thrown. In other words, a record must contain dimensions with unique names.

pub fn get_common_attributes(&self) -> &Option<Record>

A record that contains the common measure, dimension, time, and version attributes shared across all the records in the request. The measure and dimension attributes specified will be merged with the measure and dimension attributes in the records object when the data is written into Timestream. Dimensions may not overlap, or a ValidationException will be thrown. In other words, a record must contain dimensions with unique names.

pub fn records(self, input: Record) -> Self

Appends an item to Records.

To override the contents of this collection use set_records.

An array of records that contain the unique measure, dimension, time, and version attributes for each time-series data point.

pub fn set_records(self, input: Option<Vec<Record>>) -> Self

An array of records that contain the unique measure, dimension, time, and version attributes for each time-series data point.

pub fn get_records(&self) -> &Option<Vec<Record>>

An array of records that contain the unique measure, dimension, time, and version attributes for each time-series data point.
