Description

Realm is really slow to create when there are millions of objects to create. I had 332,015 polygons to create and it took me 5-10 hours to finish the job. and I can confirm that the use of SphericalMercator is not time-consuming.
My code is here
const Realm = require("realm");
const SphericalMercator = require("@mapbox/sphericalmercator");
const merc = new SphericalMercator({
{{ size: 512,}}
{{ antimeridian: true,}}
});
const TaskSchema = {
{{ name: "Polygon",}}
{{ properties: {}}
{{ _id: "int",}}
{{ minX: "double",}}
{{ minY: "double",}}
{{ maxX: "double",}}
{{ maxY: "double",}}
{{ },}}
{{ primaryKey: "_id",}}
};
async function main() {
{{ var origin = [-87.096306, 40.214224];}}
{{ var count = 0;}}
{{ const fs = require("fs");}}
{{ const path = require("path");}}
{{ const directoryPath = path.join(__dirname, "realm-files");}}
if (!fs.existsSync(directoryPath)) {
{{ fs.mkdirSync(directoryPath);}}
{{ }}}
{{ const realm = await Realm.open({}}
{{ path: "realm-files/myrealm.realm",}}
{{ schema: [TaskSchema],}}
{{ });}}
{{ for (var i = 0; i < 2500; i++) {}}
{{ if (origin[0] > -86.694305 || origin[1] > 40.563003) {}}
{{ break;}}
{{ }}}
{{ for (var j = 0; j < 2500; j++) {}}
{{ if (origin[0] > -86.694305 || origin[1] > 40.563003) {}}
{{ console.log(origin[0]);}}
{{ console.log();}}
{{ break;}}
{{ }}}
{{ var pixelOrigin = merc.px(origin, 22);}}
{{ const pixelDest1 = [pixelOrigin[0], pixelOrigin[1] - 1405.38];}}
{{ const pixelDest2 = [pixelOrigin[0] + 1405.38, pixelOrigin[1] - 1405.38];}}
{{ const pixelDest3 = [pixelOrigin[0] + 1405.38, pixelOrigin[1]];}}
{{ const cordDest1 = merc.ll(pixelDest1, 22);}}
{{ const cordDest2 = merc.ll(pixelDest2, 22);}}
{{ const cordDest3 = merc.ll(pixelDest3, 22);}}
{{ if (j == 0) {}}
{{ iter = cordDest3;}}
{{ } }}
{{ realm.write(() => {}}
{{ polygon = realm.create("Polygon", {}}
{{ _id: count,}}
{{ minX: origin[0],}}
{{ minY: origin[1],}}
{{ maxX: cordDest2[0],}}
{{ maxY: cordDest2[1],}}
{{ });}}
{{ });}}
{{ origin = cordDest1;}}
{{ count++;}}
{{ }}}
{{ origin = iter;}}
{{ }}}
}
(async () => {
await main();
})();
