Hi,
In a method we are creating a new instance of ReadOnlyTransaction and
WriteTransaction from the transaction chain and subsequently doing the read and
write operations on the datastore. When multiple requests are sent
concurrently, IllegalStateException is thrown. Is there any way to solve this
issue, apart from synchronizing the method which does the above operations ?
Method pseudocode :
doSomeTask(BindingTransactionChain txnChain) {
1) final WriteTransaction writeTxn =
txnChain.newWriteOnlyTransaction();
2) final ReadOnlyTransaction readTxn =
txnChain.newReadOnlyTransaction();
3) Read the data and close the transaction readTxn.close()
4) Write the data.
}
Exception trace :
java.lang.IllegalStateException: Previous transaction
member-1-datastore-operational-fe-0-chn-3-txn-1018 is not ready yet
