-- The following record fields are available, with the corresponding lenses provided
-- for backwards compatibility:
--
-- 'transactionId', 'commitTransactionRequest_transactionId' - Specifies the transaction ID of the transaction to commit.

-- 'commitDigest', '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.

-- -- /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.
