Method Detail

getTranslator
protected IDatabaseTranslator getTranslator()
Getter for the translator currently held by this DAO- Returns:
-
getNextResource
protected ResourceIndexRecord getNextResource(SecureRandom random, Instant reindexTstamp, Integer resourceTypeId, String logicalId) throws Exception
Pick the next resource to process resource and lock it. Specializations for different databases may use different techniques to optimize locking/concurrency control- Parameters:
reindexTstamp
-- Returns:
- Throws:
Exception
-
getResourceToReindex
public ResourceIndexRecord getResourceToReindex(Instant reindexTstamp, Integer resourceTypeId, String logicalId) throws Exception
Get the resource record we want to reindex. This might take a few attempts, because there could be hundreds of threads all trying to do the same thing, and we may see collisions which will cause the FOR UPDATE to block, then return no rows.- Parameters:
reindexTstamp
-resourceCount
-- Returns:
- the resource record, or null when there is nothing left to do
- Throws:
Exception
-
updateParameters
public void updateParameters(String tablePrefix, List<ExtractedParameterValue> parameters, String logicalId, long logicalResourceId) throws Exception
Reindex the resource by deleting existing parameters and replacing them with those passed in- Parameters:
tablePrefix
-parameters
-p_logical_id
-p_payload
-p_last_updated
-p_is_deleted
-p_source_key
-p_version
-- Throws:
Exception
-
deleteFromParameterTable
protected void deleteFromParameterTable(Connection conn, String tableName, long logicalResourceId) throws SQLException
Delete all parameters for the given resourceId from the parameters table- Parameters:
conn
-tableName
-logicalResourceId
-- Throws:
SQLException
