lib/stellar/indexer.ts imports from deleted lib/dag/ module

[grantfox-oss]

Labels: bug build cleanup
Difficulty: Medium

Summary

lib/stellar/indexer.ts imports reconstructDagFromMetaXdr from ../dag/engine and the ExecutionDag type from ../dag/types. Both of these files were removed. The import causes a build failure. The indexer also has an onDag option in its StreamingIndexerOptions interface that references the ExecutionDag type and a block of code that calls reconstructDagFromMetaXdr() inside the streaming callback.

What a Contributor Needs to Deliver

Both import statements must be removed. The onDag field must be removed from StreamingIndexerOptions. All code inside the streaming callback that references onDag or calls reconstructDagFromMetaXdr() must be removed. The remaining streaming logic must be unaffected. The file must compile cleanly after the change.

Hi team — I'd like to take this on. For "lib/stellar/indexer.ts imports from deleted lib/dag/ module" I can start with a small, tested implementation and open a PR referencing this issue shortly. Happy to coordinate if anyone's already looking at it.

Hello, my name is David Acuña, full stack developer. I checked this issue and I'd like to work on it.

This is what I'll do:

In lib/stellar/indexer.ts, I'll remove the broken imports of reconstructDagFromMetaXdr from ../dag/engine and ExecutionDag from ../dag/types, delete the onDag field from StreamingIndexerOptions, and remove the streaming-callback block that reconstructs and emits DAGs. I'll also stop destructuring onDag from the options so no dangling references remain.

The rest of the Horizon streaming path — event filtering, ingestion pool, retries, and metrics — will stay unchanged. After the cleanup, I'll confirm the file compiles cleanly and that no other callers still pass onDag.
