海外TECH	DEV Community	Best Practice for TCC Distributed Transaction In Go	https://dev.to/yedf2/best-practice-for-tcc-distributed-transaction-in-go-402m	Best Practice for TCC Distributed Transaction In GoThis article will present a complete TCC example to give the reader an accurate understanding of TCC type transactions Business ScenarioA typical distributed transaction scenario is inter bank transfers where A needs to transfer funds across a bank to B The hypothetical requirement scenario is that both transfers out of A and into B may succeed and fail and that both transfers in and out will eventually succeed or fail There is also a requirement that if there is a rollback the SAGA mode will result in A discovering that its balance has been deducted but the recipient B is late in receiving the balance which will cause A great distress The business would prefer to avoid this situation TCC ComponentsThe TCC is divided into partTry part attempts to execute completes all business checks consistency reserve necessary business resources Confirm part if all branches succeed in the Try phase then we move to the Confirm phase where Confirm actually executes the business without any business checks using only the business resources reserved in the Try phaseCancel part If one of the Trys in all branches fails we go to the Cancel phase which releases the business resources reserved in the Try phase If we were to perform a transaction similar to a bank interbank transfer with TransOut and TransIn in separate micro services a typical timing diagram for a successfully completed TCC transaction would be as follows Core OperationsFirst we create the account balance table where trading balance indicates the amount that has been frozen create table if not exists dtm busi user account id int PRIMARY KEY AUTO INCREMENT user id int UNIQUE balance DECIMAL not null default trading balance DECIMAL not null default create time datetime DEFAULT now update time datetime DEFAULT now key create time key update time Let s write the core code first the freeze unfreeze funds operation will check the constraint balance trading balance gt if the constraint is not valid the execution failsfunc tccAdjustTrading db dtmcli DB uid int amount int error affected err dtmimp DBExec db update dtm busi user account set trading balance trading balance where user id and trading balance balance gt amount uid amount if err nil amp amp affected return fmt Errorf update error maybe balance not enough return err func tccAdjustBalance db dtmcli DB uid int amount int error affected err dtmimp DBExec db update dtm busi user account set trading balance trading balance balance balance where user id amount amount uid if err nil amp amp affected return fmt Errorf update user account rows return err Let s write the specific Try Confirm Cancel handler functionsapp POST BusiAPI TccBTransOutTry dtmutil WrapHandler func c gin Context interface bb MustBarrierFromGin c return bb Call txGet func tx sql Tx error return tccAdjustTrading tx TransOutUID req Amount app POST BusiAPI TccBTransOutConfirm dtmutil WrapHandler func c gin Context interface bb MustBarrierFromGin c return bb Call

return bb Call txGet func tx sql Tx error return tccAdjustTrading tx TransInUID req Amount The core logic of these functions is to freeze and adjust the balance the role of bb Call in this will be explained in detail later TCC transactionsThen the TCC transaction is created and branch calls are made TccGlobalTransaction will open a global transaction err dtmcli TccGlobalTransaction DtmServer func tcc dtmcli Tcc rerr error CallBranch will register the Confirm Cancel of the transaction branch to the global transaction and then call Try directly res rerr tcc CallBranch amp TransReq Amount host api TccBTransOutTry host api TccBTransOutConfirm host api TccBTransOutCancel if err nil return resp err return tcc CallBranch amp TransReq Amount host api TccBTransInTry host api TccBTransInConfirm host api TccBTransInCancel At this point a complete TCC distributed transaction is finished RunIf you want to run a successful example entirety the steps are as follows run dtmgit clone amp amp cd dtmgo run main goRun the examplegit clone amp amp cd dtm examplesgo run main go http tcc barrier Handling network exceptionsSuppose a transaction committed to dtm fails briefly at one of these steps dtm will retry the incomplete operation requiring the subtransactions of the global transaction to be idempotent dtm framework pioneered the subtransaction barrier technique providing the BranchBarrier utility class to help users handle idempotency easily It provides a function Call which guarantees that the operation inside this function will be called at most once func bb BranchBarrier Call tx sql Tx busiCall BarrierBusiFunc errorThis BranchBarrier can automatically handle not only idempotency but also null compensation and hanging issues see exceptions and solutions for details Rollback of TCCWhat happens if the bank is preparing to transfer the amount to user and finds that user s account is abnormal and returns a failure We modify the code to simulate this situation app POST BusiAPI TccBTransInTry dtmutil WrapHandler func c gin Context interface return dtmcli ErrFailure This is the timing diagram for a transaction failure interactionThe difference between this and a successful TCC is that when a child transaction returns a failure the global transaction is subsequently rolled back calling the Cancel operation of each child transaction to ensure that the global transaction is all rolled back The forward operation of TransInTry returned a failure without doing anything at this point calling the TransInCancel compensation operation will cause the reverse adjustment to go wrong Don t worry the preceding subtransaction barrier technique ensures that the TransInTry error is compensated as a null operation if it occurs before the commit and that the compensation operation commits the data if the TransInTry error occurs after the commit You can change TccBTransInTry toapp POST BusiAPI TccBTransInTry dtmutil WrapHandler func c gin Context interface bb MustBarrierFromGin c bb Call txGet func tx sql Tx error return tccAdjustTrading tx TransInUID req Amount return dtmcli ErrFailure The final result balance will still be right see
