+# The pipe memory pool is 10% of the heap (~22MB at the default 224M budget),
+# while the stock pipe memory estimates are sized for datacenter nodes: each
+# pipe reserves a 15MB insert-node queue and estimates ~18MB more at task
+# startup, so CREATE PIPE fails on an untuned edge node. Shrink the per-pipe
+# queue budget and skip the startup estimation; actual allocations stay
+# elastic within the pool, degrading to batched TsFile transfer on pressure.
+# Validated on Raspberry Pi 4B: one realtime pipe ('history.enable'='false')
+# forwarding a 100-points/s load adds ~20MB RSS and syncs with sub-second
+# latency (single-record p99 < 500ms).
