Bug Fixes

​
Fusion Connectors

  • Fixed an issue to make gRPC max outbound message size configurable to prevent remote connectors from failing on large field sizes.
  • Fixed an issue where a restart was required when the remote JDBC V2 connector timed out and did not restart correctly.
  • Fixed an issue where the JDBC V2 connector failed to index data.
  • Fixed an issue where the Connectors SDK delete-by-query that contains a NOT-EQUAL phrase did not delete the appropriate documents.
  • Fixed an issue where the outbound access control list (ACL) object contained a reference to itself in the outbound_ss field by default. The plug-in that creates the ACL should enter that reference explicitly only when required.
  • Fixed an issue where the connectors-backend service did not add the following fields by default to the LDAP ACL documents: _lw_data_source_type_s, _lw_batch_id_s, _lw_data_source_collection_s, and _lw_block_start_time_l. These fields are required by the LDAP plug-in to keep the list of ACL objects up-to-date.

Known issues

  • New Kerberos security realms cannot be configured successfully in this version of Fusion.
