> Key: ZOOKEEPER-1967
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1967
> Project: ZooKeeper
> Issue Type: Improvement
> Components: quorum, server
> Reporter: Alexander Shraer
>
> The .next temporary config file is created when a server acks a reconfig
> proposal.
> During reconfig commit this file becomes the permanent dynamic config file.
> This temp file is read (if exists) during server boot to determine whether
> there is a reconfig potentially in progress.
> This info is also available in the transaction log, since reconfig is a
> transaction. Initially I chose not to take this information from the
> transaction log, mainly for simplicity, since I believed that we need the
> last proposed reconfig info before we're processing the transaction log (for
> example, if we'd like to contact new config servers during FLE - this is
> discussed in ZOOKEEPER-1807).
> It would be useful to revisit this issue and check whether we could eliminate
> the temporary dynamic config file, finding the last proposed reconfig in the
> the transaction log.
