    Crate 1.0.5 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。

    本次部分更新如下:


    • Fix: Case sensivity of aliases wasn't handled correctly.Aliases are now fully case sensitive.


    • BREAKING: The `ordinal` column at the `information_schema.columns` will return `NULL` now for all sub-columns (all non top-level columns) as the order of object columns is not guarateed.


    • Fixed a race condition that could have caused that not all columns were written to the metadata when a lot of new dynamic columns were generated concurrently.


    • Fixed an issue that caused joins on `information_schema.columns` to produce a wrong result if `information_schema.columns` was used as the right table.


    • Added cluster checks that warn if some tables need to be recreated or upgraded for compatibility with future versions of CrateDB.


    • Added functionality to monitor query runtime statistics via JMX.This feature can only be used with an enterprise license.


    • Added a new parameter ``upgrade_segments`` to the ``OPTIMIZE`` statement which enables the upgrade of tables and tables partitions to the current version of the storage engine.


    • Added new column ``min_lucene_version`` to ``sys.shards`` table, which shows the oldest lucene segment version used in the shard.


    • Remove restriction to run ``OPTIMIZE`` on blob tables.
