+A frequently asked question is why my latest message not showing up when querying with Pulsar SQL.
+It's not a bug but controlled by a setting, by default bk LAC only advanced when subsequent entries are added.
+If there is no subsequent entries added, the last entry written will not be visible to readers until the ledger is closed.
+We can add following setting to change the behavior:
+In Broker config, set
+bookkeeperExplicitLacIntervalInMills > 0
+bookkeeperUseV2WireProtocol=false
+
+And in Presto config, set
+pulsar.bookkeeper-explicit-interval > 0
+pulsar.bookkeeper-use-v2-protocol=false
