Pinterest UMS (wide-column store)

UMS is Pinterest's in-house wide-column store — one of the early HBase-backed storage services in the company's infrastructure history. The HBase deprecation retrospective names it as one of the foundational systems powered by HBase.

Definition

UMS exposes a wide-column API (akin to Bigtable / HBase) as a Pinterest-internal service, hiding raw HBase access behind a service boundary. Public information on UMS is limited to the mention in the HBase-deprecation retrospective (Source: sources/2024-05-14-pinterest-hbase-deprecation-at-pinterest).

Role in the HBase-deprecation case

UMS is one of the named services in Pinterest's HBase ecosystem diagram (Figure 1 in the source post), alongside Zen, OpenTSDB, Omid/Sparrow, Ixia, and Pinalytics. Collectively these services make HBase deprecation an organisation-level move — not just a storage-substrate swap but a family-level retirement of all HBase-backed services, each of which either migrates or rehomes.
