Hi Calvin, Thanks for the KIP.
[AL1] > When the cluster does not support the new version, the admin client will fail to build the ListTransaction request with version 2. UnsupportedVersionException will be thrown. It looks like this will make it impossible to use newer clients with older brokers, which would break backward compatibility. Instead of this, we should do what https://cwiki.apache.org/confluence/display/KAFKA/KIP-994%3A+Minor+Enhancements+to+ListTransactions+and+DescribeTransactions+APIs did, when it added a new filter: the client should only fail when the new filter is used and the broker doesn't support the new filter. -Artem On Tue, Apr 1, 2025 at 4:18 PM Calvin Liu <ca...@confluent.io.invalid> wrote: > Hi Kafka Community, > I would like to start a discussion on KIP-1152: Add transactional ID prefix > filter to ListTransactions API > The main motivation behind the KIP is to reduce the transactions included > in the ListTransactions response when the transactional IDs are > well-formatted and can be fetched with a prefix. > > The KIP will update the ListTransaction APIs, ListTransactionOptions and > kafka-transactions.sh > Thanks! > > Link to the KIP. > > https://cwiki.apache.org/confluence/display/KAFKA/KIP-1152%3A+Add+transactional+ID+prefix+filter+to+ListTransactions+API >
