LizardFS

About LizardFS

A software-defined storage solution that is distributed, parallel, scalable, fault-tolerant, and geo-redundant. LizardFS provides a highly available file system with automatic data replication and self-healing capabilities.

Key Features

• 1Open-source distributed file system forked from MooseFS with active development
• 2Master server stores metadata; chunk servers store data blocks
• 3Configurable replication goal per file or directory
• 4Erasure coding for storage-efficient redundancy on large files
• 5Geo-replication for multi-datacenter deployments

How Python Data Engineers Use LizardFS

Python data engineers in on-premise environments use LizardFS as a shared POSIX file system mounted across pipeline worker nodes. Python scripts write output files to the LizardFS mount and those files are immediately visible to all other nodes in the cluster — enabling simple shared-nothing pipeline patterns where workers write outputs that other workers consume without message queue coordination.
