记录一下config.json中data.bin的存储规则

[Antinomy20001]

读取data.bin的实现在FaissInterface.cpp的bool faissSearch::load里。

具体存储规则如下：

首先是5个int，只有前三个有意义，分别对应：数据维度(dimension)，向量数量(count)，fileFormatVersion，0，0。

接下来为count组数据，每组数据的以一个int长度的id开头，然后是dim * sizeof(float)长度的数据表示向量数据。

The implementation of reading data.bin is in bool faissSearch::load , FaissInterface.cpp.

The storage rules are as follows:

The first is 5 ints, only the first three are meaningful, corresponding to: data dimension (dimension), number of vectors (count), fileFormatVersion, 0, 0.

Next is the count group data, each group of data begins with an id length id, and then dim * sizeof (float) length data represents vector data.
