Crate 0.55.4 发布了，Crate Data 是一个开源的大规模的可伸缩的数据存储系统，无需任何系统管理需求。提供强大的搜索功能。用于存储各种表格数据、非结构化数据和二进制对象。并可通过 SQL 进行检索。易于安装和使用，支持高可用性和实时大规模并行访问和处理。Crate 特别适合用于 Docker 环境中。
本次发布主要改进如下：
- Fixed a NPE in ordered select statements.
- Fix: Inserting a duplicate primary key lead to an update on
replicas even though it resulted in a DuplikateKeyException
(introduced with version 0.55.0).
- Fix: Querying a partitioned table by a single primary key raised an
exception instead of responding whith a zero row count.
- Improved the performance of sorted join queries
