How Astra DB Billing Works
Pricing is simple from start to scale.
Pay as you go
Astra DB’s pricing is simple and transparent, based on the volume of data, and the numbers of operations.
No more sizing your database to match your application workload. Astra DB auto-scales up and down based on actual usage.
Save significant engineering and operations effort typically spent on sizing, provisioning, monitoring, and tuning.
A “Read Request Unit” (RRU) is the unit of measure for billing database reads.
It is based on the payload of each read query response.
A read request that returns up to 4KB of data is considered one RRU. If the request returns more than 4KB of data, additional RRUs are required. If the read request involves an ALLOW FILTERING query the data is measured prior to in-memory filtering.
A “Write Request Unit” (WRU) is the unit of measure for billing database writes.
It is based on the payload size of each write request.
A write request with up to 1KB of data or a DELETE request are each considered one WRU. If the request has more than 1KB of data, additional WRUs are required.
A write index SAI is considered as a write request. The write index SAI size (and the number of WRUs required) is based on the size of each indexed column (not the size of the index), regardless of the column type.
Note: Writes in a multi-region configuration are billed for each region written to.
“Data Storage” means all data stored into the Database including the data, indexes and metadata.
Storage is calculated based on logical storage consumption. Data Storage is measured in GB per month, using the maximum data stored in the given month for the usage calculation.
You are not billed extra for standard backups of your data (It is included in the base storage costs).
“Data Transfer” means the transfer of Customer Data out of the database.
Billable units and pricing vary depending on whether the Data Transfer occurs within the same cloud provider network (“Data Transfer - Within Cloud Provider Network”) or leaves the cloud provider network over the internet (“Data Transfer - Internet”).
Data Transfer charges are measured in GB.
Creating a “Private Endpoint” allows users to securely connect applications and third party SaaS offerings to Astra DB.
Users are billed at a fixed rate per hour plus data transfer charges per GB. Data transfer charges using private endpoints are for the transfer of Customer Data into and out of the database.
Cloud providers will also bill for use of private endpoint capabilities.
“Multi-Region” means replicating the database between multiple cloud regions enabling users to write to and read from multiple regions.
Additional charges include network egress between regions which is billed per GB. This cost is based on the source region. Users will also incur a one-time data transfer charge to replicate all data to the newly added region.
