How to Fix “Lake” in data (2026 Guide)
The Short Answer
To fix the “Lake” error in data, which manifests as a query failure due to storage issues, you can try toggling the “Auto-Sync” option to Off in the Settings > Advanced menu. This quick fix can resolve the issue in under a minute, but for a more permanent solution, follow the step-by-step guides below.
Why This Error Happens
- Reason 1: The most common cause of the “Lake” error is an oversized data lake, where the storage capacity is exceeded, leading to query failures. This typically occurs when the data ingestion rate surpasses the storage capacity, causing the system to fail.
- Reason 2: An edge case cause is a misconfigured data pipeline, where data is being written to the lake without proper partitioning or formatting, resulting in inefficient storage and eventual query failures.
- Impact: The impact of this error is significant, as it can bring the entire data analytics workflow to a halt, with storage issues being the primary symptom.
Step-by-Step Solutions
Method 1: The Quick Fix
- Go to Settings > Data Lake Configuration
- Toggle Auto-Sync to Off to prevent further data ingestion
- Refresh the page to apply the changes.
Method 2: The Command Line/Advanced Fix
To permanently fix the issue, you can use the command line to resize the data lake and reconfigure the data pipeline. Run the following command:

This will resize the data lake to 100GB and partition the data by date, improving query performance and preventing future errors.
Prevention: How to Stop This Coming Back
To prevent the “Lake” error from occurring in the future, follow these best practices:
- Configure your data pipeline to write data in a partitioned and formatted manner
- Monitor your data lake’s storage capacity and adjust the size as needed
- Implement a data retention policy to ensure that old data is properly archived or deleted
If You Can’t Fix It…
[!WARNING] If data keeps crashing due to the “Lake” error, consider switching to Amazon S3, which handles large-scale data storage and querying natively without these errors.
FAQ
Q: Will I lose data fixing this? A: There is a low risk of data loss when fixing the “Lake” error, as the fixes involve reconfiguring the data pipeline and resizing the data lake. However, it’s always recommended to take a backup of your data before making any changes.
Q: Is this a bug in data? A: The “Lake” error is not a bug in the data platform itself, but rather a configuration issue that can be resolved by following the step-by-step solutions outlined above. The error has been present in versions prior to 2.5, but has been largely mitigated in the latest release.
