Storing Data and Metadata

The following functions are defined to store data and metadata and to enforce indexing of metadata where necessary:

• hc_store_both_ez

• hc_store_metadata_ez

• hc_check_indexed_ez

The is_indexed value in the returned system record (hc_system_record_t) indicates whether this record was successfully inserted in the query engine at the time of store, and is hence available for query. Objects that were not inserted into the query engine at time of store are called store index exceptions. Until they are resolved, store index exceptions may or may not show up in the result sets of queries that match the store. A store index exception is resolved once the metadata for that object has been successfully inserted into the query engine, after which the object will definitely show up in the result sets of queries that match the store. The hc_check_indexed_ez method may be used to attempt to resolve a store index exception under program control. Store index exceptions will also be resolved automatically (eventually) by ongoing system healing.
