< h2 > < a name = "description" > Description< / a > < / h2 > < p > Supervisor for Machi FLU servers and their related support
servers.< / p >
< p > Our parent supervisor, < a href = "machi_flu_sup.html" > < code > machi_flu_sup< / code > < / a > , is responsible for
managing FLUs as a single entity. However, the actual
implementation of a FLU includes three major Erlang processes (not
including support/worker procs): the FLU itself, the FLU's
projection store, and the FLU's local chain manager. This
supervisor is responsible for managing those three major services
as a single "package", to be started & stopped together.< / p >
2015-05-20 03:51:25 +00:00
< p > The illustration below shows the OTP process supervision tree for
the Machi application. Two FLUs are running, called < code > a< / code > and < code > b< / code > .
The chain is configured for a third FLU, < code > c< / code > , which is not running
at this time.< / p >
< p > < img src = "/machi//images/supervisor-2flus.png" > < / p >
< ul >
< li > The FLU process itself is named < code > a< / code > .
< / li >
< li > The projection store process is named < code > a_pstore< / code > .
< / li >
< li > The chain manager process is named < code > a_chmgr< / code > . The three
linked subprocesses are long-lived < a href = "machi_proxy_flu1_client.html" > < code > machi_proxy_flu1_client< / code > < / a > processes for communicating to all
chain participants' projection stores (including the local
store < code > a_pstore< / code > ).
< / li >
< li > A fourth major process, < code > a_listener< / code > , which is responsible for
listening on a TCP socket and creating new connections.
Currently, each listener has two processes handling incoming
requests, one from each chain manager proxy.
< / li >
< li > Note that the sub-supervisor parent of < code > a< / code > and < code > a_listener< / code > does
not have a registered name.
