Stellar Index v0.5.0-rc.122

[v0.5.0-rc.122] — 2026-06-19

Fixed

• Blend reserves lookup no longer full-scans the lake. rc.121's
  /v1/lending/pools/{pool}/reserves fanned out one key_xdr= lookup per
  reserve, each a ~20s full scan of the 270M-row contract_data set (no
  skip-index on key_xdr) → handler timeout / 500. Rewritten as a SINGLE
  batched key_xdr IN (…) query with argMax for the latest version, bounded
  to a recent ledger window so it's partition-pruned (~6s on r1). An active
  Blend pool rewrites its reserves continuously so the latest state is always
  in-window. (A key_xdr bloom index would remove the bound + speed the
  wasm/code-history readers too — deferred; heavy MATERIALIZE on a shared host.)
