It is part of June '14 Monthly Activity Report.

T10.1 Data Retrieval Facilities

NKUA Activities

  • Federated Search:
    • The development of the Restful SRU consumer, the SRU RDBMS adapter and the SRU gCube Search System adapter, using the resource-aware libraries, have been completed (#1776). SRU RDBMS adapter might need some more investigation in order to retrieve the data in a more object-orient oriented way
  • Index:
    • In the context results visualization Index has been extended to support clustering capabilities of the retrieved results (#2823). A widget for visualizing the outcome of the clustering is been examined.
  • ResourceRegistry
    • Due to performance and deployment problems the underlying database of Resource Registry has changed from Derby to inmemory H2 (#2866).
  • Bug fixing:
    • Investigation of the following bug regarding Resource Registry performance that affected the SearchSystem operation (#857). In order to overcome these problems some code optimizations have been applied on Resource Registry along with the change of the underlying database.
    • Investigation of the following ticket regarding problematic behavior of the Index Service when the connectivity of the nodes that participate in the cluster is poor (#891). We decided to include nodes that belong to the same domain for each cluster until the problem is fixed in the next release of elasticsearch.
