Redis + MongoDB vs. Couchbase: Performance Benchmark Comparison

Superior performance and manageability

CHALLENGES

7 frequent challenges with Redis/MongoDB

Using MongoDB™ with Redis can enhance performance, but the combination adds significant complexity and might introduce more challenges. Because Redis lacks some features, it often needs additional modules that further complicate the setup.

CHALLENGE #1

Architecture

Redis/MongoDB is very difficult to scale from a single replica set to a fully sharded environment.

Learn more

CHALLENGE #2

Cost

MongoDB’s inability to scale increases operational costs.

Learn more

CHALLENGE #3

Replication and failover

MongoDB is highly susceptible to data loss and inconsistency.

Learn more

CHALLENGE #4

Operational overhead

Redis/MongoDB deployments require operations teams with mastery of disparate skill sets.

Learn more

CHALLENGE #5

Multi-data center deployment

When deployed in multiple geographies, MongoDB can’t perform all writes locally.

Learn more

CHALLENGE #6

Mobile

Redis lacks a mobile solution, and MongoDB’s mobile solution has significant shortcomings.

Learn more

CHALLENGE #7

Time

Redis/MongoDB is time-consuming to develop, manage, and maintain.

CODE SNIPPET

Couchbase's SQL++ and single API excels over Redis/MongoDB

				
			

// scope/collection allow for more flexible data organization
const bucket = cluster.bucket('accounts-receivable');
const scope = bucket.scope('tenant1');
const collection = scope.collection('invoices');
const result = await collection.get('key');

				
// Redis lacks scope and collection capability
const redisClient = redis.createClient({ ... });
redisClient.connect();
const value = await redisClient.get('key');

				
			

/* equivalent to the Mongo example */
SELECT SUM(value * volume) AS val, symbol
FROM   db.stocks
WHERE  symbol IN ( "AAPL", "GOOG" ) AND value > 0
GROUP  BY symbol
ORDER  BY val DESC, symbol ASC

				
			

// equivalent to the SQL++ example
db.stocks.aggregate([
	 { "$match": {
	 	 "$and": [
	 	 	 {"symbol": {
	 	 	 	 "$in": [
	 	 	 	 "AAPL",
	 	 	 	 "GOOG"]}},
	 	 	 { "value": {
	 	 	 "$gt": 0 }}]}},
	 { "$group": {
	 	 "_id": {
	 	 	 "symbol": "$symbol" },
	 	 "sum(value * volume)": {
	 	 	 "$sum": {
	 	 	 	 "$multiply": [
	 	 	 	 	 "$value",
	 	 	 	 	 "$volume"]}}}},
	 { "$project": {
	 	 "_id": 0,
	 	 "sum(value * volume)": "$sum(value * volume)",
	 	 "symbol": "$_id.symbol"}}
	 { "$sort": {
	 	 "sum(value * volume)": -1,
	 	 "symbol": 1 }}]})
