Optimization of Solana Scanning transactions history with multi-machine architecture
Solana Transactions, I met with my multi-machine architecture. By default, the two instances would treat the newspapers in isolation,
The problem: lack of data consistency
If an instance has broken down, it will continue to receive new transaction newspapers, but this can cause problems if
Mechanism and implemented a simple solution to analyze the history of transactions by block:
Analysis of the transaction by scanning by block
Here is an overview of my approach:
- Configure the journalization
: Configure the two instances with the same newspaper to capture the newspapers.
- Create a transaction scanning function :
This is where things become interesting –
`Javascript
Constitutions = {}; // initializes an empty object to store all transactions
Const Logger = ...; // Configure the Logger instance
Logtransaction asynchronous function (transaction) {
to try {
Const transactionhash = transaction.hash;
If (! Transactions [Transactionhash]) {
Transactions [transactionhash] = {};
}
For (Const Key in Transactions [Transactionhash]) {
Transactions [Transactionhash] [Key] .push (transaction);
}
} Catch (error) {
Logger.error ('Error processing transaction:', error);
}
}
Asynchronous function scantransactionhistorybyblock (blocknumber) {
Const Blockinfo = Wait Getblockinfo (Blocknumber);
Const transactionsinisblock = [];
For (Const entry de Blockinfo.transactions) {
if (entry.type === 'transaction') {
Logtransaction (entry);
}
// Add all other relevant transaction data to our database
}
}
'
Example of use cases
Here is an example of how
Javascript
Const Blockchain = ...; // Suppose we have access to the Blockchain instance
Hand asynchronous function () {
Const Blocknumber = 12345;
Wait ScantransActionhistorybyBlock (Blocknumber);
}
` ‘
This approach is decreasing, providing a reliable means of processing and validating transactions on Solana.
