v3.13.0

Summary

This release includes a lot of enhancements, improvements, bug fixes, and vulnerability fixes.

Community edition

Enhancements

• Added dynamic arbitrary filtering for non-JDBC databases. (#1682)
• Added the Insert, Upsert, and Update operations to the transactional API. (#1697)
• Added YugabyteDB adapter as one of JDBC storages (#1710)
• Added Group Commit feature for Coordinator Table (#1728)
• Allowed directly executing CRUD operations with transaction managers. (#1755)
• Added support for arbitrary filtering for partition scan and index scan. (#1763)
• Added a single CRUD operation transaction manager. This transaction manager implementation does not allow beginning a transaction by calling begin()/start(). It only allows directly executing CRUD operations from the transaction manager. (#1793)
• Added support for arbitrary filtering for get operations. (#1834)
• Added a new Admin API admin.getNamespacesNames() to list the user namespaces. Though, this API won't return a namespace that does not contain a table. From ScalarDB 4.0, we plan to improve the design to suppress this limitation. (#2002)

Improvements

• Removed the hard-coded collation for MySQL and SQL Server in the JDBC adapter. As a result, the collation configured in the underlying database will be used when creating tables. (#1518)
• Added error codes to the error messages of Schema Loader. (#1564)
• Performance improvement of the group commit by using priority queue in the background worker. (#1641)
• Refactored scan with filtering. (#1715)
• Avoided creating an internal unique index as much as possible to reduce resource consumption and improve performance. (#1723)
• Changed the hard-coded password for the Oracle user to a more secure one in the JDBC adapter. (#1765)
• Update base image of container image. This update fixes an OOM issue on a Kubernetes with cgroup v2 environment. In the previous versions, if you use a Kubernetes cluster with cgroup v2, you might face an OOM-killed issue. (#1826)
• Added capability to specify global properties for all storages in multi-storage. (#1486)
• In MySQL, ScalarDB FLOAT type is changed from DOUBLE to REAL (single-precision floating-point value) (#2000)

Bug fixes

• Upgraded the base image to fix security issues. CVE-2023-47038 (#1522 #1521)
• Upgraded the PostgresSQL lib to fix security issues. CVE-2024-1597 (#1547)
• Fixed a bug where NullPointerException occurs during the EXTRA_READ validation when scanning records in a transaction, but some of them are deleted by other transactions. (#1624)
• Fixed a bug where lazy recovery was not executed for the implicit pre-read of put and delete operations. (#1681)
• Fixed a bug where users could see inconsistent results when scanning records by an index key after putting the related records in Consensus Commit transactions. (#1727)
• Upgraded grpc_health_probe to fix security issues. CVE-2024-24790, CVE-2023-45283, and CVE-2023-45288 (#1980)
• Fixed snapshot management issues. (#1976)
• Fix a bug of the import-table feature that it could access tables in other namespace that have the same table name when using MySQL storage. (#2001)
