pub struct WriteRecordsFluentBuilder { /* private fields */ }Expand description
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§
Source§impl WriteRecordsFluentBuilder
impl WriteRecordsFluentBuilder
Sourcepub fn as_input(&self) -> &WriteRecordsInputBuilder
pub fn as_input(&self) -> &WriteRecordsInputBuilder
Access the WriteRecords as a reference.
Sourcepub async fn send(
self,
) -> Result<WriteRecordsOutput, SdkError<WriteRecordsError, HttpResponse>>
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.
Sourcepub fn customize(
self,
) -> CustomizableOperation<WriteRecordsOutput, WriteRecordsError, Self>
pub fn customize( self, ) -> CustomizableOperation<WriteRecordsOutput, WriteRecordsError, Self>
Consumes this builder, creating a customizable operation that can be modified before being sent.
Sourcepub fn database_name(self, input: impl Into<String>) -> Self
pub fn database_name(self, input: impl Into<String>) -> Self
The name of the Timestream database.
Sourcepub fn set_database_name(self, input: Option<String>) -> Self
pub fn set_database_name(self, input: Option<String>) -> Self
The name of the Timestream database.
Sourcepub fn get_database_name(&self) -> &Option<String>
pub fn get_database_name(&self) -> &Option<String>
The name of the Timestream database.
Sourcepub fn table_name(self, input: impl Into<String>) -> Self
pub fn table_name(self, input: impl Into<String>) -> Self
The name of the Timestream table.
Sourcepub fn set_table_name(self, input: Option<String>) -> Self
pub fn set_table_name(self, input: Option<String>) -> Self
The name of the Timestream table.
Sourcepub fn get_table_name(&self) -> &Option<String>
pub fn get_table_name(&self) -> &Option<String>
The name of the Timestream table.
Sourcepub fn common_attributes(self, input: Record) -> Self
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.
Sourcepub fn set_common_attributes(self, input: Option<Record>) -> Self
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.
Sourcepub fn get_common_attributes(&self) -> &Option<Record>
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.
Sourcepub fn records(self, input: Record) -> Self
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.
Sourcepub fn set_records(self, input: Option<Vec<Record>>) -> Self
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.
Sourcepub fn get_records(&self) -> &Option<Vec<Record>>
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.

fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().

Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().

painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
