Furthermore, developers must utilize and TTL (Time to Live) indexes judiciously. While Change Streams are essential for event-driven architectures, they generate additional I/O operations that are billable. Similarly, TTL indexes allow for the automatic deletion of expired data, which is a crucial mechanism for controlling storage volume and, by extension, storage costs.
In DocumentDB, a request unit (RU) is a measure of the number of read and write operations that can be performed per second. The RU is a combination of:

: Transferring data into DocumentDB from the internet is free. However, data transfer out of DocumentDB to other regions or the internet incurs standard AWS data transfer charges. Comparing Pricing Models DocumentDB Detail Replication Data is durable across 3 AZs; billed for 1 copy. Billing Unit Per-second (10-minute minimum). Max Document Size Up to 16 MB per BSON document. Index Limits Up to 64 indexes per collection. Tips for Cost Management
The second pillar of DocumentDB pricing is . In a traditional database, storage is often a fixed block attached to a server. In DocumentDB, the storage is managed automatically by AWS. Users are billed per gigabyte (GB) of storage consumed per month. A unique feature of DocumentDB is that it automatically grows the storage volume as data is added, up to a massive limit (currently 64 TiB), meaning users do not need to provision storage in advance. This eliminates the cost of wasted, unutilized disk space but requires vigilance regarding data retention policies to prevent runaway storage costs from accumulating. Furthermore, developers must utilize and TTL (Time to
Launched in 2021, serverless is revolutionary for DocumentDB users.
: Efficient indexing and query optimization can help reduce these costs by minimizing the data that needs to be read from or written to disk. 4. Backup and Data Transfer In DocumentDB, a request unit (RU) is a
