Crate 0.55.3 发布。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。 主要更新内容如下： - Fixed an issue which prevents java client from running explain statements. - Fixed an issue which caused `current_timestamp` as part of a generated expression to not work correctly. This fix will only affect new tables. Tables which already contain a generated column which uses `current_timestamp` will need to be recreated. - Improved error handling when grouping by invalid data types. - Fixed an issue when ordering by a function on a joined query. - Fixed an issue which could lead to wrong Error messages due to a race condition. - Fix: Arrays of geo_point can be used in insert/update statements as literals as well as bind arguments. - Fixed a read isolation issue which could cause joins involving system and blob tables to return inconsistent results. - On Hunspell dictionary configuration, the parameter indices.analysis.hunspell.dictionary.location has been removed and <path.conf>/hunspell i s always used. - Fixed a bug that prevented join and sort on blob tables. - Adapted behaviour of stats.enabled, stats.jobs_log_size and stats.operations_log_size settings to match behaviour of other cluster wide settings like for example minimum_master_nodes. - Fix: Do not fetch table stats when node is not fully available yet. This could have led to NullPointerExceptions during long recovery process on node start. - Fixed an issue which prevented running join queries on empty partitioned tables. - Fix: the ``hostname`` column of the ``sys.nodes`` table returns a hostname instead of an IP address. - Fixed an issue that caused select statements to get stuck if used as part of a bulk request. Now a proper error is raised. - Updated Elasticsearch to 2.3.4 - Fix: the ``within`` scalar function now allows querying geo_shapes within geo_shapes. 下载地址： Source code (zip) Source code (tar.gz) Crate 0.55.3 发布，数据存储系统下载地址
