      • initialBufferSize

        public int initialBufferSize
        Initial size of the write buffer in bytes.

      • maxBufferSize

        public int maxBufferSize
        The limit on buffer growth in bytes. Default is 64K.

      • maxBufferTimeDepth

        public long maxBufferTimeDepth
        The limit on buffer growth as difference between first and last message time. Default is Long.MAX_VALUE.

      • lossless

        public boolean lossless
        Applicable to transient streams only. When set to true, the loader will be delayed until all currently open cursors have read enough messages to free up space in the buffer. When set to false, older messages will be discarded after the buffer is filled up regardless of whether there are open cursors that have not yet read such messages. Default is false. Durable streams are always lossless.
