The in-memory storage is not intended for production workloads. It’s intended as a simple solution to get started quickly and data will be lost once the process exits.

By default, there’s no limit in the amount of traces stored in memory but a limit can be established by passing an integer value via --memory.max-traces.

Badger - local storage

• Since Jaeger v1.9

Badger  is an embedded local storage, only available with all-in-one distribution. By default, it acts as ephemeral storage using a temporary file system. This can be overridden by using the --badger.ephemeral=false option.
