Upgrade to v0.49

Breaking changes

Removed services

The following services have been removed:

  • Chainsafe service has been removed (PR-5744) - The service has been sunset.
  • libsql service has been removed (PR-5616) - Dead service removal.

Batch operations removed

PR-5393 removes the batch concept from OpenDAL. All batch-related operations and capabilities have been removed.

Capability changes

  • write_multi_align_size capability has been removed (PR-5322)
  • Added new shared capability (PR-5328)

Options-based API

New options classes have been introduced for structured operation configuration:

  • ReadOptions - for read operations
  • WriteOptions - for write operations
  • ListOptions - for list operations
  • StatOptions - for stat operations

Example usage:

// Read with options
ReadOptions options = ReadOptions.builder()
    .range(0, 1024)
    .ifMatch("etag")
    .build();
byte[] data = operator.read("path/to/file", options);

// Write with options
WriteOptions options = WriteOptions.builder()
    .contentType("text/plain")
    .cacheControl("max-age=3600")
    .build();
operator.write("path/to/file", data, options);

Upgrade to v0.48

Breaking change

PR-6169 The append method in AsyncOperator has been deprecated. Please use the write method with WriteOptions.builder().append(true).build() instead.

Upgrade to v0.46

Breaking change

PR-4641 renames async Operator to AsyncOperator and BlockingOperator to Operator.

Upgrade to v0.44

Breaking change

Because of a TLS lib issue, we temporarily disable the services-ftp feature.

Upgrade to v0.41

Breaking change for constructing operators

PR-3166 changes the API for constructing operators:

Previous:

new BlockingOperator(scheme, config);
new Operator(scheme, config);

Current:

BlockingOperator.of(scheme, config);
Operator.of(scheme, config);

Now, there is no public constructor for operators, but only factory methods. In this way, the APIs are free to do arbitrary verifications and preparations before constructing operators.
