SQL 语法 PreviousFill,GroupByFill 主体框架成型 (欢迎各位加入🔥) #931 Accelerate Previous Fill #854 Group By Fill 4. IOTDB-573 构造 AbstractIoTDBThread 类来管理所有异常 https://issues.apache.org/jira/browse/IOTDB-573 5. 合并了新的 TsFile 文件结构，写入速度与原结构相同， 但原始数据查询快了30%,聚合查询快了70%，count(*)查询快了80% 有兴趣了解更新项 欢迎访问 #855 6. 与官网仓库合二为一、在 Session 接口中增加中文字符支持、以及优化 SeriesReader、TimeGenerator 等等 Thanks --- Dawei Liu > 2020年4月3日 下午11:51，Dawei Liu <[email protected]> 写道： > > Dear community, > > > I am very happy to share with you again the IoTDB weekly news. > > The weekly has been published for 2 weeks and received enthusiastic feedback. > we update the weekly report template according to the suggestion, > more let people easy to understand IoTDB development. > > Have a good weekend. > > [Message Board] > 1.
