Introduction

In this article, we will delve into a peculiar issue that arises during historical syncs in a database. Specifically, we will explore the phenomenon of DB row updates with unexpected values, which can have significant implications for data integrity and consistency. We will examine the root cause of this issue, discuss potential solutions, and provide a step-by-step guide to reproducing the problem.

Background

The issue in question occurs in the token table, where the token_address is 0xb6617f457b33e02e6bdd973c29376a192a5b0908 and the token_id is 0. The series of events leading up to this issue is as follows:

Mint 1 on token: A record is inserted, and the total_supply is set to 1. The is_marketplace_allowed flag is set to false.
Mint 1 on token (again): The record is updated, and the total_supply is incremented to 2. The is_marketplace_allowed flag remains false.
Token contract allowed in marketplace: The is_marketplace_allowed flag is updated to true.
Mint 50 on token: The total_supply is incremented to 52, but the is_marketplace_allowed flag is unexpectedly set to false.

Analysis

At first glance, it appears that the issue lies in the indexer's code, which is responsible for updating the database during historical syncs. However, upon closer inspection, it becomes clear that the problem is not with the indexer's code. The is_marketplace_allowed flag is not being set to false by the indexer, and there is no default value set for this column.

Potential Causes

Given the complexity of the issue, there are several potential causes that need to be explored:

Store API and raw SQL interaction: The use of both the Store API and raw SQL during historical syncs may be contributing to the issue.
Database configuration: The database configuration may be playing a role in the unexpected behavior.
Indexer code: Although the indexer's code appears to be correct, there may be an issue with the way it interacts with the database.

Reproducing the Issue

To reproduce the issue, follow these steps:

Clone the repository: Clone the repository from the provided link: https://github.com/forma-dev/ponder-example.
Run the indexer: Run the indexer in both dev and prod modes to reproduce the issue.
Monitor the database: Monitor the database for any unexpected updates to the token table.

Conclusion

In conclusion, the issue of DB row updates with unexpected values during historical syncs is a complex problem that requires a thorough analysis of the database configuration, indexer code, and interaction between the Store API and raw SQL. By following the steps outlined in this article, developers can reproduce the issue and work towards a solution.

Recommendations

Based on the analysis, the following recommendations are made:

Investigate Store API and raw SQL interaction: Investigate the interaction between the Store API and raw SQL during historical syncs to determine if this is contributing to the issue.
Review database configuration: Review the database configuration to ensure that it is not playing a role in the unexpected behavior.
Audit indexer code: Audit the indexer's code to ensure that it is interacting correctly with the database.

Future Work

Future work should focus on:

Implementing a solution: Implement a solution to the issue, which may involve modifying the indexer's code or database configuration.
Testing the solution: Thoroughly test the solution to ensure that it resolves the issue and does not introduce any new problems.

Introduction

In our previous article, we explored the issue of DB row updates with unexpected values during historical syncs. In this article, we will provide a Q&A section to address some of the most frequently asked questions related to this issue.

Q: What is the root cause of the issue?

A: The root cause of the issue is not immediately apparent and requires a thorough analysis of the database configuration, indexer code, and interaction between the Store API and raw SQL.

Q: Is the issue specific to the `token` table?

A: No, the issue is not specific to the token table. It can occur in any table where the Store API and raw SQL are used during historical syncs.

Q: Can the issue be resolved by modifying the indexer's code?

A: Possibly, but it's not a straightforward solution. The indexer's code may need to be modified to ensure that it interacts correctly with the database, but this may not be enough to resolve the issue.

Q: What is the role of the Store API and raw SQL in the issue?

A: The Store API and raw SQL are used during historical syncs, and their interaction may be contributing to the issue. However, the exact role of each is not yet clear and requires further investigation.

Q: Can the issue be resolved by changing the database configuration?

A: Possibly, but it's not a guaranteed solution. The database configuration may need to be modified to ensure that it is not playing a role in the unexpected behavior, but this may not be enough to resolve the issue.

Q: What are the potential consequences of not resolving the issue?

A: If the issue is not resolved, it can lead to data inconsistencies and integrity issues, which can have significant consequences for the application and its users.

Q: How can the issue be reproduced?

A: The issue can be reproduced by following the steps outlined in our previous article, including cloning the repository, running the indexer, and monitoring the database.

Q: What are the next steps to resolve the issue?

A: The next steps to resolve the issue include investigating the interaction between the Store API and raw SQL, reviewing the database configuration, and auditing the indexer's code.

Q: Can the issue be resolved by implementing a solution?

A: Yes, a solution can be implemented to resolve the issue. However, it requires a thorough understanding of the root cause and a well-designed solution that takes into account the database configuration, indexer code, and interaction between the Store API and raw SQL.
