On disk, the data is organized by `<group>/shard-<shard_id>/<segment_id>/`. The segment is designed to support retention policy. -### 3.3 Query Nodes - -Query Nodes do not store data.

The number of Meta Nodes should always be odd, for instance, “3”. The number of Data Nodes scales based on your storage and query needs. The number of Query Nodes and Liaison Nodes depends on the expected query load and routing complexity. +When creating a BanyanDB cluster, choosing the appropriate number of each node type to configure and connect is crucial.
