Walkthrough

Updates the storage/eloq/tx_service submodule pointer and inserts an object_type field (value -1) into batch-tuple constructions in storage/eloq/ha_eloq.cc, propagated for unique-key and index-scan batch creation paths.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Review areas:
  • storage/eloq/ha_eloq.cc — confirm ordering/serialization of the added object_type and compatibility with receivers.
  • storage/eloq/tx_service submodule — verify the referenced commit exposes the updated batch-tuple arity and matching interfaces.
  • Any consumers/deserializers of batch tuples that assume the previous tuple arity.

Possibly related PRs

• update submodule #171 — modifies the same ha_eloq.cc scan/batch construction to add object_type and updates the tx_service submodule; directly related.
• Update submodule for txservice and enable module #152 — updates the storage/eloq/tx_service submodule reference; related submodule pointer change.
• chore: update txservice submodule #164 — includes a tx_service submodule update similar to this PR.

Poem

🐇 I nibble bytes beneath the moonlit run,
A tiny field added — now it's done.
Tuples tagged with minus-one, submodule hopped,
I twitch my whiskers, then I softly stop. 🥕
