Hello! Yesterday, I saw the wiki of `NiFi's Write-Ahead Log Implementation`. I saw below:
================================== Verify records have been restored ('restored flag' set to true). If not, throw IllegalStateException Obtain repo shared lock (read lock) Claim a partition that is not currently in use Increment an AtomicLong and mod by the number of partitions -> partitionIndex Try to claim (obtain a write lock on) partition[partitionIndex]. If not successful, go back to 2a. ================================== Is this `2a` pointed to the Step 2(Obtain repo shared lock (read lock)) or the 3a? Best Regards?? Thanks!
