This document lists content limits and request quotas for Data Catalog. These limits apply to each Google Cloud Console project and organization and are shared across all applications and IP addresses.
The Data Catalog API enforces the following content limits:
|Maximum number of entries
(search results latency can increase when exceeded)
|MB per Entry||10 MB|
|Maximum number of search results per page||1000|
|Fields per TagTemplate||500|
|Length of field name in TagTemplate||512 bytes|
|Length of resource name for a TagTemplate||512 bytes|
|Length of string field in TagTemplate||10000 bytes|
|Max number of enum values in Tag Template||100|
|Tags per Entry||1000|
The QPS of projects in an organization are added together to calculate the organization's QPS, and the project and organization have the same QPS quota. This provides flexibility to allow users to allocate quota among the organization's projects.
Currently, Data Catalog does not support quota increases.
