CrateDB is designed for real-time analytics at scale, combining the power of SQL with the flexibility of distributed systems. But as data volumes grow, traditional storage often becomes a bottleneck. High-ingest workloads, multi-zone replication, and real-time querying all demand fast and resilient storage—something many standard solutions fall short on.
Simplyblock delivers block storage that’s built for scale—low-latency, zone-independent, and highly available. It’s a strong fit for CrateDB deployments that need consistent write speed, replication safety, and operational simplicity without tying storage to a specific cloud zone or hardware configuration.
Why CrateDB Needs Smarter Storage
CrateDB excels in distributed data processing, but performance can degrade when the underlying storage isn’t designed to handle high-concurrency I/O or geographic redundancy. When relying on local disks or EBS volumes bound to specific availability zones, failure recovery and scale-out operations become complex and slow.
Simplyblock eliminates these constraints with NVMe-over-TCP storage that scales across zones and hosts. It supports disaggregated storage, enabling better resource utilization and fault isolation for CrateDB clusters—especially in environments that demand high availability and fast recovery.

Step 1: Set Up Simplyblock Volume for CrateDB
Start by creating a simplyblock volume and connecting it to your CrateDB node:
sbctl pool create cratedb-pool /dev/nvme0n1
sbctl volume add cratedb-volume 200G cratedb-pool
sbctl volume connect cratedb-volume
Then format and mount the volume:
mkfs.ext4 /dev/nvme0n1
mkdir -p /var/lib/crate
mount /dev/nvme0n1 /var/lib/crate
For full CLI reference, check the simplyblock Documentation.
Step 2: Configure CrateDB to Use the Mounted Volume
Once mounted, direct CrateDB to store data on the simplyblock volume by modifying the crate.yml file:
path:
data: /var/lib/crate
Restart the CrateDB service for the changes to take effect. The node will now store all data and logs on the simplyblock volume.
See more options in the CrateDB Configuration Reference.
Step 3: Monitor and Resize Storage Without Downtime
You can check performance and health using:
sbctl stats
To resize the volume when storage needs increase, use:
sbctl volume resize cratedb-volume 500G
resize2fs /dev/nvme0n1
This allows live scaling with zero service impact—ideal for growing analytics clusters and simplification of data management.
Step 4: Tune for Performance and Scalability
To get the most out of CrateDB on simplyblock, start by using EC2 Nitro-based instances that offer higher disk IOPS and throughput. Configure balanced sharding across nodes to distribute workload evenly and avoid resource hotspots. Regular query profiling and index tuning also help minimize unnecessary disk access, which directly improves performance.
Ongoing monitoring is essential—tools like pidstat, iostat, and CrateDB’s admin UI provide visibility into how your system behaves under load. These practices help maintain predictable performance even as workloads grow. For more technical insights, you can refer to CrateDB Performance Tips.
Step 5: Build a Resilient Multi-Zone CrateDB Cluster
CrateDB supports clustering and node replication, but storage tied to zones can limit failover. Simplyblock’s zone-independent volumes replicate across zones, maintain data integrity during outages, and speed up recovery.
This is especially useful in multi-availability zone disaster recovery use cases, where downtime isn’t an option.
Keeping CrateDB Consistent as It Grows
As CrateDB clusters scale out to handle more ingest and query load, your storage needs to keep pace without adding operational complexity. Simplyblock allows storage volumes to grow alongside your datasets—without reconfiguring nodes or experiencing downtime.
Because the volumes aren’t locked to a zone, they stay available even as your infrastructure evolves. This lets your teams scale CrateDB horizontally, rebalance shards, and support multi-zone resilience while keeping performance steady.
Questions and Answers
CrateDB handles large-scale time-series and analytical workloads, which rely on fast writes. Simplyblock’s NVMe over TCP storage reduces write latency and increases IOPS, allowing CrateDB to ingest high volumes of data without slowing down queries or cluster performance. You can see how simplyblock handles high-performance NVMe storage for databases for more details.
Yes, CrateDB uses replication for high availability, but replication can be slowed by storage I/O bottlenecks. Simplyblock accelerates replication by providing low-latency NVMe storage, ensuring faster synchronization between nodes and more reliable failover in distributed deployments. Learn more about the distributed storage systems that simplyblock supports.
Scaling CrateDB often requires adding more nodes and storage manually. Simplyblock allows elastic provisioning of NVMe volumes, so clusters can grow automatically as data expands. This ensures consistent throughput and low latency, even in large, multi-node deployments. For guidance on scaling databases in containerized environments, see Kubernetes Stateful Workloads.
Yes, simplyblock optimizes storage usage by consolidating volumes and implementing automated tiering. This prevents overprovisioning while keeping performance high. Organizations can also reference AWS Storage Optimization for cost-effective strategies when running CrateDB in the cloud.
To deploy CrateDB with simplyblock, provision NVMe-TCP volumes for each node or configure a Kubernetes StorageClass for persistent volumes. Simplyblock handles replication, snapshots, and failover, ensuring CrateDB clusters remain highly available. For deployment best practices, see How the CSI Container Storage Interface Works.
