Fail Fast on Configurable Limit Size

Oct 13, 2025 by recoveryshake.com 142 views

Background

In the context of our system, we are constantly evolving to accommodate larger transactions while ensuring that these transactions adhere to specific limits and types. This story focuses on implementing validations to guarantee that the transactions we process meet these requirements. As we introduce the capability to handle bigger transactions, it is crucial to verify that they do not exceed certain size limits and are of the correct type.

Acceptance Criteria

To ensure that our ingest workflow checks are comprehensive and effective, we have established the following acceptance criteria:

1. Fail Fast on Configurable Limit Size

We will add a validation in the parseAndCheck method to immediately fail if the transaction size exceeds the configurable limit size. This validation will be a critical component in preventing oversized transactions from being processed.

2. Verify Transaction Type

To ensure that we are processing the correct type of transactions, we will add a check to verify that the transaction type is indeed EthereumTransaction. This will help us maintain the integrity of our system and prevent potential errors.

3. Validate Ethereum Data Fields

We will also add a check to verify that the ethereum_data fields are within the specified limit. This validation will help us prevent data overflow and ensure that our system can process transactions efficiently.

Dependencies

To complete this story, we will rely on the following dependencies:

1. Jumbo Transaction Configuration

We will need to reference the story that introduces the jumbo transaction configuration, which has not been created yet. Once this configuration is in place, we can proceed with implementing the ingest workflow checks.

Q: What is the purpose of adding ingest workflow checks?

A: The primary goal of adding ingest workflow checks is to ensure that transactions are processed efficiently and reliably. By implementing these checks, we can prevent oversized transactions from being processed, verify that transactions are of the correct type, and validate the ethereum_data fields to prevent data overflow.

Q: Why is it essential to verify the transaction type?

A: Verifying the transaction type is crucial to ensure that we are processing the correct type of transactions. This helps maintain the integrity of our system and prevents potential errors.

Q: What is the significance of validating the `ethereum_data` fields?

A: Validating the ethereum_data fields is essential to prevent data overflow and ensure that our system can process transactions efficiently. By checking that these fields are within the specified limit, we can prevent potential issues and maintain the reliability of our system.

Q: How will the ingest workflow checks be implemented?

A: The ingest workflow checks will be implemented by adding validations to the parseAndCheck method. This will involve checking that the transaction size does not exceed the configurable limit size, verifying that the transaction type is EthereumTransaction, and validating the ethereum_data fields.

Q: What are the dependencies required to complete this story?

A: The dependencies required to complete this story include the jumbo transaction configuration, which has not been created yet. Once this configuration is in place, we can proceed with implementing the ingest workflow checks.

Q: How will the implementation be tested?
