Interface Session

All Superinterfaces:
AutoCloseable
All Known Implementing Classes:
SessionImpl

@Deprecated public interface Session extends AutoCloseable
Deprecated.
Vespa-http-client will be removed in Vespa 8. It's replaced by vespa-feed-client
A Session is an entity used to feed operations (like documents, removes or updates) to one Vespa cluster or several clusters in parallel. Current implementations are fail-fast, i.e. all feeding errors are propagated to the user as quickly as possible and with as much detail as possible. Implementations of this interface are required to be thread safe. A SessionFactory is provided to instantiate Sessions.

    • stream

      OutputStream stream(CharSequence documentId)
      Deprecated.
      Returns an OutputStream that can be used to write ONE operation, identified by the given document ID. The data format must match the FeedParams.DataFormat given when this Session was instantiated. Note that most data formats include the document ID in the actual buffer, which must match the document ID given as a parameter to this method. It is (as always) important to close the OutputStream returned - nothing is written to the wire until this is done. Note also that the Session holds a certain, dynamically determined maximum number of document operations in memory. When this threshold is reached, OutputStream.close() will block.
      Parameters:
      documentId - the unique ID identifying this operation in the system
      Returns:
      an OutputStream to write the operation payload into
    • results

      BlockingQueue<Result> results()
      Deprecated.
      Returns Results for all operations enqueued by stream(CharSequence). Note that the order of results is non-deterministic, with one exception - results for one document ID are returned in the order they were enqueued. In all other cases Results may appear out-of-order.
      Returns:
      a blocking queue for retrieving results

    • close

      void close()
      Deprecated.
      Closes this Session. All resources are freed, persistent connections are closed and internal threads are stopped.
      Specified by:
      close in interface AutoCloseable
      Throws:
      RuntimeException - in cases where underlying resources throw on shutdown/close
    • getStatsAsJson

      String getStatsAsJson()
      Deprecated.
      Returns stats about the cluster.
      Returns:
      JSON string with information about cluster.
