No Metadata Keys + +When using bounded iterators, metadata keys (like `BS:H` in blockstore) are **not included**. + +**Workaround**: Use `UpdateBlockStoreHeight()` function after patching. + +#### 2. Application-Level Filtering for Specific Heights + +Specific heights use encompassing range iterator + application filter. + +**Impact**: Less efficient than continuous ranges, but still much better than full scan. + +#### 3. No Cross-Version Support + +Patching between different Cronos versions may fail if database formats differ. + +**Mitigation**: Use matching versions for source and target nodes. + +#### 4. No Rollback on Failure + +If patching fails midway, there's no automatic rollback. + +**Mitigation**: Always backup before patching. Can re-run patchdb to complete. + +#### 5. Limited Database Support + +Only `blockstore` and `tx_index` supported. + +**Reason**: These are the only databases with height-encoded keys.

The latest data wins. + +**Q: Can I patch from a newer version to an older version?** + +A: Not recommended. Database formats may differ between versions. + +**Q: Does patchdb verify the patched data?** + +A: No, patchdb doesn't have verification mode. Ensure source data is valid before patching. + +**Q: Can I use patchdb for application.db?** + +A: No, only blockstore and tx_index are supported. Use `migrate-db` for application.db. + +**Q: What if my target database doesn't exist yet?** + +A: Use `migrate-db` to create it first, then use `patchdb` to add specific heights. + +**Q: How long does patching take?** + +A: Depends on the number of heights: +- Single block: seconds +- 100K range: minutes +- 1M range: tens of minutes + +**Q: Can I patch from a different backend type?** + +A: Yes, use `--source-backend` and `--target-backend` flags to specify different types. + +--- + ## Contributing When adding new features: diff --git a/cmd/cronosd/dbmigrate/height_filter.go

During **patching** (not full migration), when an `H:` key is patched, the block hash is extracted from its value and used to look up and patch the corresponding `BH:` key automatically. For full migrations, BH: keys are included in the complete database scan. #### TX Index Bounded Iterator -Single iterator with height range: +**CRITICAL**: tx_index keys use format `tx.height/{height}/{hash}` where height is a **decimal string** (not zero-padded).
