A hundred thousand commands
Over a typical network round trip, where pipelining is transformative
commands: 100000 rtt-ms: 0.5 pipeline-depth: 200
Redis Pipeline Calculator
Give the command count and the network round-trip time. The result shows the sequential and pipelined timings and where the difference comes from.

Nothing else to flag.
No formatting problems, and nothing the rules object to. Worth remembering what that covers: this reads the file you pasted, not the account or cluster it will be applied to.
No finding matches that filter.
Examples
Real input you can load into the tool above. Each one shows a different thing going wrong, because that is what the tool is for.
Too large a batch
A batch big enough to risk the client output buffer limit
commands: 1000000 rtt-ms: 0.5 pipeline-depth: 50000
Common mistakes
These are the ones that fail silently. The config is accepted, nothing raises an error, and the consequence arrives later.
Treating a pipeline as a transaction
Commands from other clients interleave freely between pipelined commands. Only MULTI/EXEC or a script is atomic.
Instead:Use MULTI or Lua where atomicity is required.
Batching without bound
The client holds every reply and the server buffers the output. A very large batch can trip client-output-buffer-limit and have the connection closed.
Instead:A few hundred to a few thousand captures almost all the benefit.
Pipelining over a unix socket and expecting a large gain
The saving is round trips, and a local socket round trip is already tiny.
Instead:Measure first. The benefit scales with network latency.
