# Data freshness higher than configured

+ **Symptom:** `DataFreshness` is significantly higher than the configured interval.
+ **Causes:** A high number of source or Iceberg table partitions; large table metadata or many accumulated snapshots; (less commonly) transient service issues or low source throughput.
+ **Resolution:** Verify your partitioning is appropriate for the data and avoid excessive partition cardinality. Check whether the table has grown large metadata or many snapshots and, if so, enable [S3 Tables maintenance](https://docs.aws.amazon.com/AmazonS3/latest/userguide/s3-tables-maintenance.html) (compaction and snapshot expiration) to keep the table performant. For low-throughput topics, increasing the configured data freshness gives the Channel more time to accumulate data for efficient delivery.
