GB (read as "Ji"). In fact, the smallest storage unit in computer language is bit (read as "bit"), the computer's representation of many data are binary units, and 1 bits represents a binary digit, only 0 or 1;byte is the most commonly used in the computer unit, 8bit 1byte, Many places with 1b represent 1BIT,1B represent 1byte. 1 kilobyte equals 1000byte (10 bytes, or 1024byte, of 1kilobyte equals 2 for binary calculations in the computer). The conversion of some other units is described below:

sstable was on disk it was effectively immutable because an insert or delete would require a large I/O rewrite of th E file. Have said that, for static indexes It's a great solution:read in the index, and all always one disk seek away, or Simply the memmap entire file to memory. The Random reads is fast and easy. Random writes was much harder and expensive, that's, unless the entire table is in memory, in which case we ' re back to Si Mple pointer manipulation. Turns out, this is the very probl
