What is the retention period of logs stored in Jaeger for tracing?
There's nothing in Jaeger about retention period for logs, either for logs stored in spans, nor for logs generated by Jaeger components themselves.
If the OP refers to traces as "logs", then the retention is controlled by the storage backend, e.g. Cassandra tables have TTLs, and Elasticsearch can be explicitly configured to retire indices.
