此版本更新内容如下： - Updated crate-admin to 0.16.0 which includes following changes: - The table list is now fully searchable and sorted by table name within its schemas. - fix: charts are not correctly displayed in Microsoft Edge browser. - UDC: identify anonymous user with cluster id. Both user id and cluster id are anonymous traits. Note: You can disable UDC via the `udc.enabled` setting on the Crate server. - implement ``intersects`` scalar function - fix: properly restrict partitioned by columns to primitive types during analysis - added functionality to index and match geo shapes - restrict WITHIN function to only accept geo_point (and compatible types) as first argument - Added snapshot and restore functionality - Changed crate launch scripts to no longer support extending the CRATE_CLASSPATH environment variable - Added initial limited cross and inner join support - Updated crate/elasticsearch for improved logging on graceful shutdown errors - Added ``array_cat``, ``array_unique`` and ``array_difference`` scalar functions. Also modified ``concat`` function to resolve to ``array_cat`` when ``concat`` function is called with 2 array args, so the operator ``||`` will work with arrays. 下载：https://github.com/crate/crate/archive/0.53.0.zip。 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。 Crate Data 0.53.0 发布，数据存储系统下载地址
