Summary of Changes

Hello @feeblefakie, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request backports a critical fix aimed at enhancing the handling of large data within Object Storage. It addresses potential limitations by significantly increasing the maximum allowed string length for internal serialization processes and, more importantly, implements a robust validation mechanism for BLOB column values. This validation proactively checks the size of BLOBs before storage, ensuring they do not exceed a calculated limit and preventing data integrity issues, thereby improving the system's resilience when dealing with substantial binary data.

Highlights

  • Increased Maximum String Length: The maximum allowed string length for JSON serialization within Object Storage has been set to Integer.MAX_VALUE by configuring the ObjectMapper's StreamReadConstraints.
  • BLOB Column Size Validation: A new validation check has been introduced for BLOB columns in Object Storage operations. It ensures that the size of a BLOB value, considering Base64 encoding, does not exceed a calculated maximum derived from the MAX_STRING_LENGTH_ALLOWED.
  • New Error Type: A specific error, OBJECT_STORAGE_BLOB_EXCEEDS_MAX_LENGTH_ALLOWED, has been added to CoreError to be thrown when a BLOB column value exceeds its permitted size.
  • Unit Tests for BLOB Size Check: New unit tests have been added to ObjectStorageOperationCheckerTest to verify that BLOB columns within the allowed size pass validation, and those exceeding it correctly trigger an IllegalArgumentException.
  • Integration Test Refactoring: Utility methods prepareGet and preparePuts in DistributedStorageIntegrationTestBase have been changed from private to protected to allow for greater reusability in subclasses.

Code Review

This pull request increases the maximum allowed string length for Object Storage, which enables storing larger BLOB values. The change involves updating the Jackson ObjectMapper's stream read constraints and adding a pre-emptive check for BLOB column sizes in ObjectStorageOperationChecker. The implementation is sound and includes relevant unit tests. I have one suggestion to improve the clarity of an error message to make it more helpful for developers.
