Kafka uses regular Linux disk files for storage. We recommend using the EXT4 or XFS
file system. Improvements to the XFS file system show improved performance characteristics for
Kafka workloads without compromising stability.
Do not use mounted shared drives or any network file systems with
Kafka, due to the risk of index failures and (in the case of network
file systems) issues related to the use of MemoryMapped files to
store the offset index.
Encrypted file systems such as SafenetFS are not supported for
Kafka. Index file corruption can occur.
