Metacat

Convert SQLExceptions to RuntimeExceptions for Hazelcast MapStore operations.

In IdentifierManager, throw SQLExceptions rather than just logging them, and let them be handled higher up in the stack.

use new endpoint/method:

use PUT /obsoletedBy/{pid} for CNCore.setObsoletedBy per our discussion today

Keep the hzIdentifiers set in sync with the Metacat systemmetadata table. If entries are added/updated in the hzSystemMetadata map, make sure the identifier is in the set. If (for some administrative reason) the entry is removed, remove the identifier from the set. This usually doesn't happen.

When loading all keys from Metacat into the hzSystemMetadata map, also load identifiers into the hzIdentifiers set if they are not already there. Although entries may be evicted from the map, the list of identifiers will remain. The list will have a fairly small memory footprint since it's just identifiers.

Add support for the distributed Set of unique identifiers in the storage cluster called 'hzIdentifiers'. This set is a persistent total list of all identifiers (even when entries in the hzSystemMetadata map are evicted). It reflects the state of the identifiers in the postgresql systemmetadata table, but is distributed across the cluster. Add the getIdentifiers() method, which returns the ISet of identifiers.

Add the dataone.hazelcast.storageCluster.identifiersSet property that defines the name of the distributed set of unique DataONE identifiers (called 'hzIdentifiers'). This ISet can't be configured in the hazelcast.xml file (only maps and queues can).

Continued authoring the description of DataONE in Metacat. More to come.

include new methods needed for replication (in new d1 jars)
