<center><h1>VNODE Write Processes</h1></center>
## META Operations
META data write operations including:
1. create table
2. drop table
3. alter table
We take create table as an example to figure out the whole process.
```plantuml
@startuml create_table
skinparam sequenceMessageAlign center
skinparam responseMessageBelowArrow true
participant APP as app
box "dnode1"
participant RPC as rpc
participant VNODE as vnode
participant SYNC as sync
end box
box "dnode2"
participant SYNC as sync2
participant VNODE as vnode2
end box
box "dnode3"
participant SYNC as sync3
participant VNODE as vnode3
end box
' APP send request to dnode and RPC in dnode recv the request
app ->rpc: create table req
' RPC call vnodeProcessReq() function to process the request
rpc -> vnode: vnodeProcessReq
note right
callback function
run in RPC module
threads. The function
only puts the request
to a vnode queue.
end note
' VNODE call vnodeProcessReqs() function to integrate requests and process as a whole
vnode -> vnode: vnodeProcessReqs()
note right
integrate reqs and
process as a whole
end note
' sync the request to other nodes
vnode -> sync: syncProcessReqs()
' make request persistent
' sync -->vnode: walWrite()\n(callback function)
' replicate requests to other DNODES
sync -> sync2: replication req
sync -> sync3: replication req
sync2 -> vnode2: walWrite()\n(callback function)
sync2 --> sync: replication rsp\n(confirm)
sync3 -> vnode3: walWrite()\n(callback function)
sync3 --> sync: replication rsp\n(confirm)
' send apply request
sync -> sync2: apply req
sync -> sync3: apply req
' vnode apply
sync2 -> vnode2: vnodeApplyReqs()
sync3 -> vnode3: vnodeApplyReqs()
' call apply request
sync --> vnode: vnodeApplyReqs()\n(callback function)
' send response
vnode --> rpc: rpcSendRsp()
' dnode send response to APP
rpc --> app: create table rsp
@enduml
```
## Time-series data Operations
There are only one operations for time-series data: data insert. We will figure out the whole process.
```plantuml
@startuml create_table
skinparam sequenceMessageAlign center
skinparam responseMessageBelowArrow true
participant APP as app
box "dnode1"
participant RPC as rpc
participant VNODE as vnode
participant SYNC as sync
end box
box "dnode2"
participant SYNC as sync2
participant VNODE as vnode2
end box
box "dnode3"
participant SYNC as sync3
participant VNODE as vnode3
end box
' APP send request to dnode and RPC in dnode recv the request
app ->rpc: insert data req
' RPC call vnodeProcessReq() function to process the request
rpc -> vnode: vnodeProcessReq
note right
callback function
run in RPC module
threads. The function
only puts the request
to a vnode queue.
end note
' VNODE call vnodeProcessReqs() function to integrate requests and process as a whole
vnode -> vnode: vnodeProcessReqs()
note right
integrate reqs and
process as a whole
end note
' sync the request to other nodes
vnode -> sync: syncProcessReqs()
' ' make request persistent
' ' sync -->vnode: walWrite()\n(callback function)
' ' replicate requests to other DNODES
sync -> sync2: replication req
sync -> sync3: replication req
' vnode apply
sync2 -> vnode2: vnodeApplyReqs()
sync3 -> vnode3: vnodeApplyReqs()
' call apply request
sync --> vnode: vnodeApplyReqs()\n(callback function)
' send response
vnode --> rpc: rpcSendRsp()
' dnode send response to APP
rpc --> app: insert data rsp
@enduml
```
## vnodeProcessReqs()
```plantuml
@startuml vnodeProcessReqs()
participant VNODE as v
participant SYNC as s
group vnodeProcessReqs()
' Group requests and get a request batch to process as a whole
v -> v: vnodeGetReqsFromQueue()
note right
integrate all write
requests as a batch
to process as a whole
end note
' VNODE call syncProcessReqs() function to process the batch request
v -> s: syncProcessReqs()
group syncProcessReqs()
' Check if current node is leader
alt not leader
return NOT_LEADER
end
s -> s: syncAppendReqsToLogStore()
group syncAppendReqsToLogStore()
s -> v: walWrite()
note right
There must be a
callback function
provided by VNODE
to persist the
requests in WAL
end note
alt (no unapplied reqs) AND (only one node OR no meta requests)
s -> v: vnodeApplyReqs()
note right
just use the woker
thread to apply
the requests. This
is a callback function
provided by VNODE
end note
else other cases need to wait response
s -> s:
note right
save the requests in log store
