The findandmodify command the group commands are not honoring the maxTimeMS option.
Here is an example using the findandmodify command:
$ ./mongo MongoDB shell version: 2.5.5 connecting to: test Server has startup warnings: 2014-02-03T19:24:05.729-0500 [initandlisten] 2014-02-03T19:24:05.729-0500 [initandlisten] ** NOTE: This is a development version (2.5.5) of MongoDB. 2014-02-03T19:24:05.729-0500 [initandlisten] ** Not recommended for production. 2014-02-03T19:24:05.729-0500 [initandlisten] > for (var i = 1; i <= 1000000; i++) db.testData.insert( { x : i } ) SingleWriteResult({ "writeErrors" : [ ], "writeConcernErrors" : [ ], "nInserted" : 1, "nUpserted" : 0, "nUpdated" : 0, "nModified" : 0, "nRemoved" : 0, "upserted" : [ ] }) > db.testData.stats() { "ns" : "test.testData", "count" : 1000000, "size" : 48000144, "avgObjSize" : 48, "storageSize" : 86310912, "numExtents" : 10, "nindexes" : 1, "lastExtentSize" : 27869184, "paddingFactor" : 1, "systemFlags" : 1, "userFlags" : 1, "totalIndexSize" : 32458720, "indexSizes" : { "_id_" : 32458720 }, "ok" : 1 } > db.runCommand( { "findandmodify" : "testData", "query" : { "z" : 1 }, "update" : { "$inc" : { "x" : 1 } }, "maxTimeMS" : 1 } ) { "value" : null, "ok" : 1 } > db.runCommand( { "findandmodify" : "testData", "query" : { "z" : 1 }, "update" : { "$inc" : { "x" : 1 } }, "maxTimeMS" : 10 } ) { "value" : null, "ok" : 1 } > db.runCommand( { "findandmodify" : "testData", "query" : { "z" : 1 }, "update" : { "$inc" : { "x" : 1 } }, "maxTimeMS" : 100 } ) { "value" : null, "ok" : 1 }
In the server logs I see:
2014-02-03T19:53:34.262-0500 [conn1] command test.$cmd command: { findandmodify: "testData", query: { z: 1.0 }, update: { $inc: { x: 1.0 } }, maxTimeMS: 1.0 } keyUpdates:0 numYields:0 locks(micros) w:219550 reslen:44 219ms
2014-02-03T19:53:38.555-0500 [conn1] command test.$cmd command: { findandmodify: "testData", query: { z: 1.0 }, update: { $inc: { x: 1.0 } }, maxTimeMS: 10.0 } keyUpdates:0 numYields:0 locks(micros) w:195078 reslen:44 195ms
2014-02-03T19:53:43.077-0500 [conn1] command test.$cmd command: { findandmodify: "testData", query: { z: 1.0 }, update: { $inc: { x: 1.0 } }, maxTimeMS: 100.0 } keyUpdates:0 numYields:0 locks(micros) w:213143 reslen:44 213ms
Similar for the group command:
> db.runCommand( { group: { key: "z", $reduce: function ( curr, result ) { }, initial: {}, maxTimeMS: 100.0, ns: "testData" } } )
{ "retval" : [ { } ], "count" : 1000000, "keys" : 1, "ok" : 1 }
and in the log:
2014-02-03T20:03:21.412-0500 [conn1] command test.$cmd command: { group: { key: "z", $reduce: function ( curr, result ) { }, initial: {}, maxTimeMS: 100.0, ns: "testData" } } keyUpdates:0 numYields:0 locks(micros) r:6083207 reslen:83 6083ms
Note: I am only manually creating the commands so I can inspect the full results.
