v1.5.14

Sling v1.5.14 (2026-04-06T15:41:03Z)

New Features

• SQL Server BCP with Entra ID authentication: BCP bulk loading now supports Entra ID token-based auth and Azure CLI integration for passwordless authentication.
• DuckDB Arrow IPC streaming: Implement Arrow IPC streaming for DuckDB connections, improving read/write performance.
• CDC full-refresh mode: Added support for full-refresh mode with CDC options, clearing state before running an initial snapshot.
• CDC UUID primary key support: CDC initial snapshots now handle string/UUID primary keys with offset-based chunking, in addition to integer PKs.
• length() function supports scalar types: The length() function now safely handles integers, floats, booleans, and dates by converting to string representation, allowing use in wildcard transforms with ternary guards.
• sling project jobs run --wait flag: New --wait / -w flag polls execution status every 5 seconds until the job reaches a terminal state, then reports rows, bytes, and duration.
• OAuth2 custom credentials and spec URL: Enhanced OAuth2 initialization to support custom client credentials and spec URL for flexible token management.

Bug Fixes

• Oracle sqlldr column sizing: Fixed sqlldr control file generation to use target column precision instead of hardcoding char(400000), preventing excessive memory allocation during Oracle bulk imports.
• TINYINT type handling: Corrected data type mapping for tinyint in metadata queries across MariaDB, MySQL, and StarRocks templates.
• Cross-platform path handling: Replaced path package with filepath across the codebase for correct behavior on Windows.
• Token save in agent mode: Allow local SaveToken to proceed even when running in agent mode.
