Description and Constraints

  1. For the PSI operator, the input is of the string type, and the output is the intersecting string or the indices (int type) of the intersecting string.
  2. The PSI operator supports two-party and three-party operations. The maximum length of data transmitted between nodes is 32 GB to prevent memory overflow.
  3. The number of input data records cannot exceed INT32_MAX.
  4. The communication callback relies on a secure, encrypted transmission channel established by the calling party. The section "API Call Demos" provides a socket-based implementation for reference.
  5. Resource configuration reference: According to the local benchmark test results, when 10 million 11-byte string data records (about 105 MB) are processed, the memory usage of the PSI operator is greater than or equal to 1810 MB, which is about 17.2 times the original data size.
