Crate.IO 大规模数据存储系统
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。
数据存储系统 Crate 1.0.4 版本发布了。
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
