45-65: Consider optimizing batch processing for large datasets.The current implementation loads all batches into memory before processing them. While the comment suggests an expected capacity of 100, this could be problematic for larger datasets.
Consider processing batches in chunks to manage memory more efficiently:
func migrateOutgoingTxBatchBlockKey(ctx sdk.Context, storeKey storetypes.StoreKey, cdc codec.BinaryCodec) { kvStore := ctx.KVStore(storeKey) iter := storetypes.KVStorePrefixIterator(kvStore, types.OutgoingTxBatchBlockKey) defer iter.Close() - batches := make([]*types.OutgoingTxBatch, 0, 100) for ; iter.Valid(); iter.Next() { batch := new(types.OutgoingTxBatch) cdc.MustUnmarshal(iter.Value(), batch) - batches = append(batches, batch) + newBlockKey := types.GetOutgoingTxBatchBlockKey(batch.Block, batch.BatchNonce) + kvStore.Set(newBlockKey, cdc.MustMarshal(batch)) kvStore.Delete(iter.Key()) } - - for _, batch := range batches { - newBlockKey := types.GetOutgoingTxBatchBlockKey(batch.Block, batch.BatchNonce) - kvStore.Set(newBlockKey, cdc.MustMarshal(batch)) - } }This approach:
- Processes each batch immediately
- Reduces memory usage
- Maintains the same functionality

39-43: Consider adding migration safety checks.The current migration process lacks validation steps that could prevent data loss in case of interruption or errors.
Consider adding the following safety measures:
- Validate the new key format before deleting old keys
- Add a migration status tracker
- Implement rollback capability
Would you like me to provide a detailed implementation of these safety measures?
13-14: Verify the necessity of adding a new deprecated variable.Adding a new variable that's immediately marked as deprecated seems counterintuitive, especially since it's not used in the migration functions. Additionally, the AI summary indicates this key is removed in
x/crosschain/types/key.go.Let's verify the usage and necessity of this key:
✅ Verification successful
Let me gather more context about this migration and the key's usage.
Based on the gathered information, I can now provide a final response:
The deprecated variable declaration is part of a proper migration strategy
The git history and specification documentation reveal that
OutgoingTxPoolKeywas previously an active part of the system (as shown intypes/key.goremoval diff) and was used for indexing outgoing transaction pools. The key's presence in the migration file serves two purposes:
- Documentation of the historical key value (0x18) for future reference
- Maintaining the constant during the migration process, even though it's marked as deprecated
Unlike other removed keys that are included in
GetRemovedStoreKeys(), this key is not actively removed during migration, suggesting it might be handled differently or in a subsequent upgrade.This is a common practice in migration files to document the deprecation process while ensuring a smooth transition.
