What does SPI stand for?

Maybe this is blindingly obvious to others, but I can't seem to find
reference to what SPI stands for?
http://apacheignite.gridgain.org/v1.1/docs/cluster-config
<http://apacheignite.gridgain.org/v1.1/docs/cluster-config>  

e.g.  org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi
<https://ignite.apache.org/releases/mobile/org/apache/ignite/spi/discovery/tcp/TcpDiscoverySpi.html>  

Shared/Server/Socket/? ... Protocol/Port/?... Identifier/Interface/??....

Can someone enlighten me please? (Thanks)

Hi,

SPI stands for Service Provider Interface. In Ignite it is an isolated
abstracted component which can be plugged in to provide new or
replace/extend existing functionality.

For example, you can implement your own CollisionSPI to control how
ComputeJobs are scheduled on a local node, or extend TcpCommunicationSpi to
add compression to communication layer.

Please refer to IgniteSPI javadoc and it's various implementations for
further details.

Hope this helps,
