/** 时间戳转日期 */ const timestampToDate = (timestamp: any) => { if (timestamp == null || timestamp == undefined) return ""; const date = new
可以使用SimpleDateFormat类来格式化时间戳,将其转换为指定的日期字符串。下面是一个代码示例: longtimestamp=System.currentTimeMillis();SimpleDateFormatsdf=newSimpleDateFormat("yyyy-MM-dd HH:mm:ss");StringformattedDate=sdf.format(newDate(timestamp));System.out.println("格式化后的日期:"+formattedDate);...

To improve performance (significantly), formatted date parts are computed lazily rather than when a timestamp object is instantiated, and the computed parts are then cached for later access without recomputing. Behind the scenes, this avoids unnecessary(string-to-number (format-time-string...calls...

TsFile employs advanced encoding and compression techniques to optimize storage and access for time series data. It uses methods like run-length encoding (RLE), bit-packing, and Snappy for efficient compression, allowing separate encoding of timestamp and value columns for better data processing. It...
