Partition stream by (wiki_id, page_id)
Partition page_source
by (wiki_id
, page_id
).
This change is mostly cosmetic (not perf related) and syncs mw-page-content-change-enrich
partition scheme
with the key pair declared by eventgate for this stream.
Tested with live traffic on eqiad, with no regression wrt the previous partitioning scheme (by wiki_id
). Metrics checked:
- watermark lag.
- avg time for async operations.
- ps util memory.
