Overview
Cloud Talent Solution v4 is the latest version in General Availability (GA). Cloud Talent Solution v4 consolidates features from several previous versions ( v3, v3p1beta1, and v4beta1. With the release of v4, all previous versions (v3, v3p1beta1, and v4beta1) are now deprecated. Calls to deprecated versions (v3p1beta1, v4beta1, and v3) will be unsuccessful starting October 14, 2021.
Functionality changes
Some critical functional changes between v4 and older versions are outlined in the table below. For a complete picture of functionality changes we recommend that you review the release notes.
| Functional changes | Older versions | v4 |
|---|---|---|
| Multi-tenancy support | Supported starting from v4beta1. Both tenant and non-tenant paths are supported in v4beta1. | Tenant path is now required. To migrate from non-tenant path to tenant path, use the listTenants API to find the tenant and add it to tenant path. |
| Batch operations | Batch Operations in v3 and v3p1beta1 are synchronous. v4beta1 upgrades the BatchCreate and BatchUpdate to asynchronous operations. | BatchDelete is added as a Batch Operation, and all Batch Operations continue to be asynchronous. |
| Histogram Facets | Supported in v3 and v3p1beta1. Starting from v4beta1 HistogramFacets is not supported and is replaced by Histogram Query, which offers more flexibility by using an expression. |
Only Histogram Query is supported (same as v4beta1). |
CompanyName |
The field is called companyName in v3 and v3p1beta1 and renamed to company in v4beta1. |
The field name is company (same as v4beta1). |
requirePreciseResultSize |
Deprecated in v3, v3p1beta1, and v4beta1. | Deleted from v4 because all search calls now return precise results. |
estimatedTotalSize |
Deleted from v4 because all search calls now return precise results and this field has the same value as totalSize. |
|
CommuteMethod |
Walking and cycling were Beta options in v4beta1. They will remain Beta features only available in v4beta1 until approximately Q1 2021, at which time these features will be generally available and included in v4. | COMMUTE_METHOD_UNSPECIFIED, DRIVING, and TRANSIT are the only CommuteMethod options available in v4 until Q1 2021. |
SearchJobsRequest.max_page_size |
Named SearchJobsRequest.page_size in all previous versions. |
Renamed to max_page_size in v4. |
SearchJobsForAlertRequest.max_page_size |
Named SearchJobsForAlertRequest.page_size in all previous versions. |
Renamed to max_page_size in v4. |
Tenant.usage_type |
The Tenant.usage_type field was added in v4beta1. |
This field has been removed in v4. Data within a tenant is only used to improve search quality within that tenant. |
