Pertanyaan geo MongoDB3.2.10 adalah masalah terlalu perlahan
Versi
Mongo3.2.10
Soalan
Pertanyaan geo pengelompokan padat mengembalikan 30 rekod terkini, yang memerlukan pengimbasan 20,000+ rekod.
Untuk set titik yang sama, cuba buat pertanyaan indeks 2d dan indeks 2dsphere, dan kecekapan pelaksanaan tidak jauh berbeza.
