This is often caused by a hot partition and not using the shard-aware driver.

Checkout the `nodetool toppartitions` command.

Hi,

Currently we are using ScyllaDB version 4.4.7 and read the data using Spark Cassandra Connector 2.5.2 as we use Spark 2.4.7 . We don't know if the Connector supports Shard Awareness as there is no mention of it on the github page of the Connector. Could you please help in guiding us how to enable shard awareness or if there is any driver /connector specific to ScyllaDB as we couldn't find any specific Spark connector for ScyllaDB.

Thanks & Regards

ScyllaDB 4.4.7 is past end-of-life, please upgrade to a supported version.

I don't know enough about the spark connector, you can try asking on the forum.
