+component: tempostack

+# A brief description of the change. Surround your text with quotes ("") if it needs to start with a backtick (`).
+note: Use the ReadinessProbe to better indicate when tempo-query is ready to accept requests. Improving the startup reliability by avoiding lost data.

+# One or more tracking issues related to the change
+issues: [1058]

+# (Optional) One or more lines of additional information to render under the primary note.
+# These lines will be padded with 2 spaces and then inserted directly into the document.
+# Use pipe (|) for multiline entries.
+subtext: Without a readiness check in place, there is a risk that data will be lost when the queryfrontend pod is ready but the tempo query API is not yet available.
