crate 0.49.4 发布，更新内容如下： - Fixed issue that could lead to deadlock and therefore freezing of a node when there where too many queries asking for routing information in parallel. - Fix: Querying from information_schema while a table is created could cause an error - only log amazon s3 client stuff on level ``WARN`` - log failing uri on COPY FROM - Fixed a NPE that was thrown if a SELECT statement contained `_score` in the result columns and an ORDER BY clause. - Fix: selecting error from sys.jobs_log caused a NPE in some cases - Fix: If a query would fail because a shard starts to relocate during query time, the query is retried now - Fix: load Crate plugins only once on node start - Fixed an issue that caused `sys.shards` queries to omit unassigned shards if the query was made against a node that has `node.data` set to false - Fix: Fixed a bug where some searchers were not properly closed - Fixed a race condition that could cause `DROP TABLE IF EXISTS` to fail if the table was concurrently dropped. - Fixed a race condition in `ALTER TABLE <partitioned_table>` that could occur if a `DELETE FROM <partitioned_table>` was invoked immediately before the `ALTER TABLE` statement. 更多内容请查看更新日志。 该版本下载： Source code (zip) Source code (tar.gz) 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。 使用方法： crate 0.49.4 发布，大规模数据存储系统下载地址
