) ### What problem does this PR solve? Issue Number: N/A Related PR: #57264 Problem Summary: Cloud streaming jobs query Meta Service for progress while replaying each job update journal, making FE replay depend on Meta Service availability and RPC latency. ALTER already persists the updated offset provider state and job statistics in the journal. Restore the provider state and cloud statistics locally during replay instead of querying Meta Service. A paused job therefore retains its altered offset and journaled statistics after an FE restart, before RESUME. PENDING scheduling still fetches the authoritative committed progress from Meta Service before dispatching tasks, and pauses the job if that fetch fails. ### Release note Cloud streaming jobs restore journaled offsets and statistics during FE replay without querying Meta Service. Progress is still synchronized from Meta Service before consumption resumes.
