Known Issues

The Kafka source connector CDC strategy depends on Neo4j Change Data Capture identifiers. CDC change identifiers can become invalid after operations such as restoring a backup, restoring from a snapshot, copying a database, importing data through CLI commands, or pausing and resuming a Neo4j Aura database. They can also become invalid when the transaction log gets truncated and no longer contains the transaction referenced by the stored change identifier.
