#9877 fix: Add warning when using ephemeral state ID in el/elt commands Pull request opened by stbiadmin Description When

meltano elt

or

meltano el

is run without

--state-id

, an ephemeral timestamp-based state ID is generated silently. This means incremental replication state is not persisted between runs, which can be surprising — especially for users who expect state to "just work" across pipeline executions. This PR adds a warning log message when no

--state-id

is provided, informing the user that: • An ephemeral state ID is being used • Incremental replication state will not be reused • They should pass

--state-id=<your_id>

to persist state The warning is emitted in

_run_el_command()

before the

Job

is created, covering both the

el

and

elt

commands.

New Features: • Log a warning when el/elt commands run without an explicit --state-id, indicating that an ephemeral state ID is being used and incremental state will not be persisted. Tests: • Add CLI tests for el and elt commands to assert that the ephemeral state ID warning is emitted when no --state-id is provided. meltano/meltano
