数据存储系统 Crate 1.0.4 版本发布了。

Crate 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。

1.0.4 更新内容:

- Fixed an issue which caused restoring a whole partitioned table from a snapshot to fail.

 - Fixed the low/high disk-based shard allocation watermark settings. When a percentage value is provided for either of settings, it won't be converted to an absolute byte value.

 - Fix: Index columns based on string arrays are correctly populated with values.

 - Updated crate-admin to ``1.0.5`` which includes the following change:

    - Fixed a console results issue that caused the results table not to be displayed after horizontal scrolling.

    - Fixed an issue that caused the admin-ui to load only one plugin.

    - Display warning in the console view when the query result contains an unsafe integer.

    - Relocated the help resources section to be underneath the tweet import tutorial.

    - Show loading indicator when `Execute Query ` is in progress.

 - Fixed evaluation on ``UPDATE`` of generated columns without referenced columns, e.g. generated columns with a ``CURRENT_TIMESTAMP`` expression.

 - Fixed global aggregations on JOINs with 3 or more tables.

 - Removed limitation which didn't allow ordering on partitioned columns in GROUP BY query
