Command to fetch a page.

Specifies the session token for the current command. A session token is constant throughout the life of the session.

To obtain a session token, run the StartSession command. This SessionToken is required for every subsequent command that is issued during the current session.

Command to abort the current transaction.

Command to end the current session.

Command to start a new transaction.

Command to execute a statement in the specified transaction.

Command to commit the specified transaction.

Command to start a new session. A session token is obtained as part of the response.

Contains the details of the fetched page.

Contains the details of the aborted transaction.

Contains the details of the ended session.

Contains the details of the started transaction.

Contains the details of the executed statement.

Contains the details of the committed transaction.

Contains the details of the started session that includes a session token. This SessionToken is required for every subsequent command that is issued during the current session.

The response's http status code.

Contains server-side performance information for the command.

Specifies the transaction ID of the transaction to commit.

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.

Contains server-side performance information for the command.

Contains metrics about the number of I/O requests that were consumed.

The commit digest of the committed transaction.-- -- 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.

The transaction ID of the committed transaction.

Contains server-side performance information for the command.

Specifies the parameters for the parameterized statement in the request.

Specifies the transaction ID of the request.

Specifies the statement of the request.

Contains server-side performance information for the command.

Contains metrics about the number of I/O requests that were consumed.

Contains the details of the first fetched page.

Specifies the transaction ID of the page to be fetched.

Specifies the next page token of the page to be fetched.

Contains server-side performance information for the command.

Contains metrics about the number of I/O requests that were consumed.

Contains details of the fetched page.

The number of read I/O requests that the command made.

The number of write I/O requests that the command made.

The token of the next page.

A structure that contains values in multiple encoding formats.

The name of the ledger to start a new session against.

Contains server-side performance information for the command.

Session token of the started session. This SessionToken is required for every subsequent command that is issued during the current session.

Contains server-side performance information for the command.

The transaction ID of the started transaction.

The amount of time that QLDB spent on processing the command, measured in milliseconds.

An Amazon Ion plaintext value contained in a ValueHolder structure.

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.
