To avoid the need for a mutex in ServerWriteConcernMetrics, we will remove the arbitrary maps. The opWriteConcernCounters will be reduced to:
opWriteConcernCounters: {
insert: {
wmajority: <num>,
wnum: {
"0": <num>, // only generate these fields if they are used
"2": <num>,
"3": <num> // only include wnum up to 3
},
none: <num>
},
update: {
wmajority: <num>,
wnum: {
"0": <num>, // only generate these fields if they are used
"2": <num>,
"3": <num> // only include wnum up to 3
},
none: <num>
},
delete: {
wmajority: <num>,
wnum: {
"0": <num>, // only generate these fields if they are used
"2": <num>,
"3": <num> // only include wnum up to 3
},
none: <num>
}
}
Note that the wtags section is removed, and we only include wnum up to 3. This can be extended back to the full syntax described in SERVER-38998 later on.
