  - ### Method Detail

    - #### spiStart

          public void spiStart(@Nullable
                               @Nullable String igniteInstanceName)
                        throws IgniteSpiException

      This method is called to start SPI. After this method returns successfully kernel assumes that SPI is fully operational.
      Specified by:
        `spiStart` in interface `IgniteSpi`
      Parameters:
        `igniteInstanceName` - Name of Ignite instance this SPI is being started for (`null` for default Ignite instance).
      Throws:
        `IgniteSpiException` - Throws in case of any error during SPI start.

    - #### spiStop

          public void spiStop()
                       throws IgniteSpiException

      This method is called to stop SPI. After this method returns kernel assumes that this SPI is finished and all resources acquired by it are released.

      Note that this method can be called at any point including during recovery of failed start. It should make no assumptions on what state SPI will be in when this method is called.

      Specified by:
        `spiStop` in interface `IgniteSpi`
      Throws:
        `IgniteSpiException` - Thrown in case of any error during SPI stop.

    - #### setMetricRegistry

          public void setMetricRegistry(ReadOnlyMetricManager registry)

      Sets metrics registry that SPI should export. This method called before `IgniteSpi.spiStart(String)`.
      Specified by:
        `setMetricRegistry` in interface `MetricExporterSpi`
      Parameters:
        `registry` - Metric registry.

    - #### setExportFilter

          public void setExportFilter(Predicate<ReadOnlyMetricRegistry> filter)

      Sets export filter. Metric registry that not satisfy `filter` shouldn't be exported.
      Specified by:
        `setExportFilter` in interface `MetricExporterSpi`
      Parameters:
        `filter` - Filter.
