Read Replica for Analytics
A read replica for analytics is a continuously synced, read-only copy of a production database used to run reports and heavy analytical queries without slowing down the live application.
In Depth
Analytical queries are greedy: a single revenue-by-cohort scan can chew through CPU and I/O that your checkout flow needs. A read replica isolates that risk—the database continuously streams changes to a copy, analytics runs against the copy, and production stays fast. Replicas are typically seconds behind the primary, which is fine for almost all reporting. For teams adopting AI query tools, pointing the tool at a replica is the standard pattern: everyone can ask anything, as often as they like, with zero chance of impacting customers.
How AI for Database Helps
AI for Database can connect to a read replica just like a primary—same plain-English querying, zero load on production.

Query latency is the time between submitting a database query and receiving its results.
Read-Only Mode
Read-only mode is a safety configuration in which a tool or database connection can run SELECT queries to read data but is blocked from any operation that modifies it—no INSERT, UPDATE, DELETE, or schema changes.
Operational Analytics
Operational analytics is the use of current, granular data to drive day-to-day decisions and actions—monitoring orders, signups, inventory, and queues as they move—rather than reviewing historical summaries.
