How Simplyblock Strengthens Memgraph Persistence?

Memgraph is a high-performance, in-memory graph database built for real-time analytics and graph-based applications. While its in-memory architecture makes it extremely fast, reliable persistence is required for durability, recovery, and scaling. If the storage layer cannot keep up, checkpoints, durability logs, and replication may slow down or fail.

Simplyblock provides NVMe-over-TCP storage and zone-independent volumes to ensure persistence in Memgraph remains fast, durable, and highly available across environments.

Memgraph Performance Tied to Storage

Memgraph uses durability logs and periodic snapshots to persist data. The efficiency of these operations depends on storage throughput. Without optimized volumes, checkpoints may lag, logs can grow uncontrollably, and failovers may risk data loss.

By pairing Memgraph with simplyblock, administrators gain consistent performance for both transactional workloads and snapshot persistence. Zone independence further guarantees storage access even during node rescheduling.

Step 1: Provisioning Simplyblock Volumes for Memgraph

Start by creating and attaching volumes to handle Memgraph’s durability logs and snapshots:

sbctl pool create memgraph-pool /dev/nvme0n1

sbctl volume add memgraph-store 150G memgraph-pool

sbctl volume connect memgraph-store

Format and mount the volume:

mkfs.ext4 /dev/nvme0n1

mkdir -p /var/lib/memgraph

mount /dev/nvme0n1 /var/lib/memgraph

Update /etc/fstab:

/dev/nvme0n1 /var/lib/memgraph ext4 defaults 0 0

Step 2: Configuring Memgraph Persistence on Simplyblock

Update the Memgraph configuration file to point to the simplyblock-backed storage:

In /etc/memgraph/memgraph.conf:

–data-directory=/var/lib/memgraph

–durability-enabled=true

Restart Memgraph:

sudo systemctl restart memgraph

Persistence details are explained in the Memgraph FAQ on durability.

Step 3: Expanding Memgraph Storage for Larger Graphs

As datasets grow, checkpoint files and durability logs will require additional storage. Simplyblock supports resizing without downtime:

sbctl volume resize memgraph-store 300G

resize2fs /dev/nvme0n1

This scaling approach works well alongside software-defined storage solutions that simplify distributed data management.

Step 4: Multi-Zone Availability for Memgraph

Real-time graph workloads often demand high availability. Traditional storage tied to a single zone makes this difficult. Simplyblock’s zone-independent volumes ensure Memgraph maintains persistence even when workloads are rescheduled across availability zones.

This strengthens recovery strategies and complements approaches such as disaggregated storage for modern infrastructure.

Step 5: Replicating Memgraph Data with Simplyblock

In addition to Memgraph’s built-in replication, storage-level replication further improves durability. Simplyblock enables volume replication across zones:

sbctl volume replicate memgraph-store –zones=zone-a,zone-b

This ensures minimal data loss and fast recovery during failures. Clustering concepts are described in the Memgraph clustering overview.

Handling Storage Expansion in Memgraph

At scale, Memgraph requires persistence that is fast, reliable, and easy to manage. Simplyblock provides CLI-driven commands for provisioning, resizing, and replicating storage, reducing administrative overhead.

Features such as KubeVirt Storage expand deployment flexibility. For detailed technical references, administrators can use the simplyblock Documentation.
