qdrant-horizontal-scaling

Horizontal scaling distributes data across multiple Qdrant nodes using shards, while vertical scaling increases resources on a single node. Horizontal scaling is preferred for growing deployments requiring fault tolerance.

Determine Qdrant node and shard counts by diagnosing current data growth and performance goals. Capacity planning guidelines recommend shard configurations and replication factors based on your specific operational scale.

Resharding in Qdrant involves reconfiguring shards across new nodes to balance data distribution. Apply operational guidance to add nodes and execute resharding strategies for growing deployments.

Configure Qdrant replication factors by setting the number of replicas for each shard across cluster nodes. This fault-tolerance planning ensures data availability when nodes fail during scaling operations.

Choose Qdrant horizontal scaling when data growth outpaces single-node capacity or when fault tolerance across multiple nodes is required. Vertical scaling suits smaller deployments with adequate single-machine resources.
