When trying to view the data on a collection which has documents with big arrays in it, the compass UI gets completely unresponsive. The same problem is encountered in Aggregations tab as well.
The problem is common for most of IoT projects, it's not unusual to see such documents there.
Below the script to simulate the issue:
const DATA_SIZE = 60 * 60 * 12 // every second for 12 hours const adjectives = 'autumn hidden smiling bitter misty'.split(' ') const nouns = 'waterfall river carefully breeze moon rain'.split(' ') const getRandomNumber = limit => (Math.random() * limit).toFixed(4) * 1 function insertData(left, right, coll) { print(`inserting: ${left}-${right} `) coll.insert({ serverName : `${left}-${right}`, hostName : `${left}${right}.local`, eventName : right, data : generateRandomData(DATA_SIZE) }) } function generateRandomData(size) { var temp = [] for(let i = 0; i < size; i++ ) { temp.push({ ts : new Date().getTime() + i, v : i + getRandomNumber(1000) }) } return temp } function populateCollection(coll) { coll.drop() coll.createIndex({serverName: 1, eventName: 1}) adjectives.forEach(adj => nouns.forEach(noun => insertData(adj, noun, coll))) } populateCollection(db.iot) print('Enjoy!')
