Data Source Types

Primary Data Sources

Data sources that are not used for replication. Operations on these data sources are not performed asynchronously and therefore they have to succeed for the operation to complete without errors. Read and search operations are only performed on primary data sources. Currently all delivered data source implementations are primary data sources.

Secondary Data Sources

Data sources that are used for replication. They are only included in write operations, therefore a secondary data source cannot be read only. Read and search operations are only performed on primary data sources. Currently no implementations of secondary data sources are available.

Read-Only Data Sources

Data sources that can only be used for read and search operations. The most common example is a corporate LDAP server that contains all the users in a company. In most cases, a company does not want to allow applications like a portal to create, modify or delete users or groups on their corporate LDAP server. In this case, the LDAP server can be configured as read only.

Writeable Data Sources

Data sources that allow create, modify and delete operations.
