Class BufferedUpdates

  • All Implemented Interfaces:
    Accountable
    class BufferedUpdates
extends java.lang.Object
implements Accountable
    Holds buffered deletes and updates, by docID, term or query for a single segment. This is used to hold buffered pending deletes and updates against the to-be-flushed segment. Once the deletes and updates are pushed (on flush in DocumentsWriter), they are converted to a FrozenBufferedUpdates instance and pushed to the BufferedUpdatesStream.
