Poem

🐰 A pointer hops to a new hash today,
No code changes come along the way,
Just a reference shift, clean and small,
The submodule glides through it all! 📍

Repo: eloqdata/eloqdoc PR: 211
File: src/mongo/db/modules/eloq/cmake/build_eloq_log_service.cmake:26-80
Timestamp: 2025-09-25T12:24:06.434Z
Learning: The user githubzilla implemented a fix in commit fe98aaf to address the MEMORY state incorrectly triggering RocksDB discovery in build_eloq_log_service.cmake. This was a control flow issue where MEMORY builds were falling into an else branch that still attempted RocksDB discovery.

File: src/mongo/db/modules/eloq/CMakeLists.txt:54-55
Timestamp: 2025-11-28T10:55:21.020Z
Learning: In src/mongo/db/modules/eloq/CMakeLists.txt, the CMake options EXT_TX_PROC_ENABLED, FORK_HM_PROCESS, and STATISTICS are used by the data_substrate submodule build system and should be retained as configuration interface options.

1-1: Submodule addition is properly configured.

The data_substrate submodule has been added (not updated) with commit dd1e7fd02d3d9170f01a6f74d3d9f63567ade3ac pointing to https://github.com/eloqdata/tx_service.git. The commit hash format is valid and the message aligns with the PR objective ("Fix create index memory unbounded"). The CMakeLists.txt retains the required options (EXT_TX_PROC_ENABLED, FORK_HM_PROCESS, STATISTICS).
