Easy: MongoDB Multi-Document ACID Transactions
Just like relational transactions
• Multi-statement, familiar relational syntax
• Easy to add to any application
• Multiple documents in 1 or many collections and databases
ACID guarantees
• Snapshot isolation, all or nothing execution
• No performance impact for non-transactional operations
Planning
• MongoDB 4.0: replica set
• MongoDB 4.2: extended to sharded clusters
13. 13
Fully Indexable
Fully featured secondary indexes
• Primary Index
– Every Collection has a primary key index
• Compound Index
– Index against multiple keys in the document
• MultiKey Index
– Index into arrays
• Text Indexes
– Support for text searches
• GeoSpatial Indexes
– 2d & 2dSphere indexes for spatial geometries
• Hashed Indexes
– Hashed based values for sharding
Index Types
• TTL Indexes
– Single Field indexes, when expired delete the document
• Unique Indexes
– Ensures value is not duplicated
• Partial Indexes
– Expression based indexes, allowing indexes on subsets of data
• Case Insensitive Indexes
• supports text search using case insensitive search
• Sparse Indexes
– Only index documents which have the given field

Compared to SQL JOINs and aggregation
SELECT
city,
SUM(annual_spend) Total_Spend,
AVG(annual_spend) Average_Spend,
MAX(annual_spend) Max_Spend,
COUNT(annual_spend) customers
FROM (
SELECT t1.city, customer.annual_spend
FROM customer
LEFT JOIN (
SELECT address.address_id, city.city,
address.customer_id, address.location
FROM address LEFT JOIN city
ON address.city_id = city.city_id
) AS t1
ON
(customer.customer_id = t1.customer_id AND
t1.location = "home")
) AS t2
GROUP BY city;
SQL queries have a
nested structure
Understanding the outer
layers requires
understanding the inner
ones
So SQL has to be read
“inside-out”
17. 17
db.customers.aggregate([
{
$unwind: "$address",
},
{
$match: {"address.location": "home"}
},
{
$group: {
_id: "$address.city",
totalSpend: {$sum: "$annualSpend"},
averageSpend: {$avg: "$annualSpend"},
maximumSpend: {$max: "$annualSpend"},
customers: {$sum: 1}
}
}
])
Versatile: Complex queries fast to create, optimize, & maintain
MongoDB’s aggregation framework has the flexibility you need to get
value from your data, but without the complexity and fragility of SQL
These “phases” are distinct and
easy to understand
They can be thought about in
order… no nesting.
