RequestTags
Optional. The request tags for the request. Request tags are user-provided strings used for usage
monitoring, cost management, and observability. Callers can associate custom application context (such as
component, microservice, feature name, or operation type) with database requests. These tags are collected
and aggregated in usage and monitoring reports, allowing billable operations and usage metrics to be sliced
and analyzed by tag. These tags only show up in monitoring and are visible in administrative operations
(such as usage reports). They do not affect data storage, query semantics, or request execution. Cardinality
and Best Practices: - Request tags are most effective when using a bounded set of distinct values (e.g.,
fewer than 100 distinct tags across an entire database). Using a large number of distinct tags may result in
tags being omitted from top usage dashboards. - Use structured identifiers (for example: app=cart,
env=prod, service=checkout) and avoid high-cardinality values such as UUIDs, request IDs, timestamps,
user IDs, or document keys. - Do not include sensitive data or personally identifiable information (PII) in
request tags, as they show up in administrative monitoring. The tags are processed as follows: - Leading and
trailing whitespace is trimmed. - Empty tags (after trimming) are filtered out. - Truncated to a maximum of
510 characters. - Deduplicated within the same request. - Limited to a maximum of 50 tags per request
(excess tags are silently discarded).
