The transactional data APIs for Amazon QLDB

Instead of interacting directly with this API, we recommend using the QLDB driver or the QLDB shell to execute data transactions on a ledger.

If you are working with an AWS SDK, use the QLDB driver. The driver provides a high-level abstraction layer above this QLDB Session data plane and manages SendCommand API calls for you. For information and a list of supported programming languages, see Getting started with the driver in the Amazon QLDB Developer Guide.
If you are working with the AWS Command Line Interface (AWS CLI), use the QLDB shell. The shell is a command line interface that uses the QLDB driver to interact with a ledger. For information, see Accessing Amazon QLDB using the QLDB shell.

Service Configuration

defaultService :: Service Source #

API version 2019-07-11 of the Amazon QLDB Session SDK configuration.

Errors

Error matchers are designed for use with the functions provided by Control.Exception.Lens. This allows catching (and rethrowing) service specific errors returned by QLDBSession.

InvalidSessionException

_InvalidSessionException :: AsError a => Getting (First ServiceError) a ServiceError Source #

Returned if the session doesn't exist anymore because it timed out or expired.

CapacityExceededException

_CapacityExceededException :: AsError a => Getting (First ServiceError) a ServiceError Source #

Returned when the request exceeds the processing capacity of the ledger.

OccConflictException

_OccConflictException :: AsError a => Getting (First ServiceError) a ServiceError Source #

Returned when a transaction cannot be written to the journal due to a failure in the verification phase of optimistic concurrency control (OCC).

RateExceededException

_RateExceededException :: AsError a => Getting (First ServiceError) a ServiceError Source #

Returned when the rate of requests exceeds the allowed throughput.

BadRequestException

_BadRequestException :: AsError a => Getting (First ServiceError) a ServiceError Source #

Returned if the request is malformed or contains an error such as an invalid parameter value or a missing required parameter.

LimitExceededException

_LimitExceededException :: AsError a => Getting (First ServiceError) a ServiceError Source #

Returned if a resource limit such as number of active sessions is exceeded.

Waiters

Waiters poll by repeatedly sending a request until some remote success condition configured by the Wait specification is fulfilled. The Wait specification determines how many attempts should be made, in addition to delay and retry strategies.

Operations

Some AWS operations return results that are incomplete and require subsequent requests in order to obtain the entire result set. The process of sending subsequent requests to continue where a previous request left off is called pagination. For example, the ListObjects operation of Amazon S3 returns up to 1000 objects at a time, and you must send subsequent requests with the appropriate Marker in order to retrieve the next page of results.

Operations that have an AWSPager instance can transparently perform subsequent requests, correctly setting Markers and other request facets to iterate through the entire result set of a truncated API operation. Operations which support this have an additional note in the documentation.

Many operations have the ability to filter results on the server side. See the individual operation parameters for details.

Arguments

:: Text	`$sel:transactionId:CommitTransactionRequest'`
-> ByteString	`$sel:commitDigest:CommitTransactionRequest'`
-> CommitTransactionRequest

Create a value of CommitTransactionRequest with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:transactionId:CommitTransactionRequest', commitTransactionRequest_transactionId - Specifies the transaction ID of the transaction to commit.

$sel:commitDigest:CommitTransactionRequest', commitTransactionRequest_commitDigest - Specifies the commit digest for the transaction to commit. For every active transaction, the commit digest must be passed. QLDB validates CommitDigest and rejects the commit with an error if the digest computed on the client does not match the digest computed by QLDB.

The purpose of the CommitDigest parameter is to ensure that QLDB commits a transaction if and only if the server has processed the exact set of statements sent by the client, in the same order that client sent them, and with no duplicates.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

newTimingInformation :: TimingInformation Source #

Create a value of TimingInformation with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:processingTimeMilliseconds:TimingInformation', timingInformation_processingTimeMilliseconds - The amount of time that QLDB spent on processing the command, measured in milliseconds.

Create a value of ValueHolder with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:ionText:ValueHolder', valueHolder_ionText - An Amazon Ion plaintext value contained in a ValueHolder structure.

$sel:ionBinary:ValueHolder', valueHolder_ionBinary - An Amazon Ion binary value contained in a ValueHolder structure.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.
