Guides Qdrant scaling decisions. Use when someone asks 'how many nodes do I need', 'data doesn't fit on one node', 'need more throughput or QPS', 'CPU is pegged / can't keep up with the request rate', 'one query is slow / p99 or tail latency too high', 'cluster is slow', 'too many tenants', 'vertical or horizontal', 'how to shard', 'need to add capacity', 'large limit / pagination / scroll is slow', or 'only recent data matters / expiring old vectors / retention window'.

Qdrant Scaling
Route first, then answer. Match the user's symptom in the table, Read that file, and answer from it. Do not answer from this page alone: it contains routing only, not the guidance. If two rows match, read both.

Data does not fit on a single node, running out of disk or memory as the dataset grows

Need to shard the collection across more nodes, data outgrew one node

Can't hold the request rate, CPU is pegged
scaling-qps/SKILL.md
A single query is too slow, need to cut the tail latency of individual requests

p99 or tail latency too high, but traffic/QPS is fine

Queries return very large result sets and slow down
scaling-query-volume/SKILL.md
Large limit, top-1000 queries, pagination, scroll across shards

Already vertically maxed out, need more nodes, resharding

Latency and throughput pull opposite ways on segment count. For latency, increase segments toward the CPU core count (defaultsegmentnumber: 16). For throughput, use fewer and larger segments (defaultsegmentnumber: 2). Applying the wrong direction makes the reported problem worse.
