In 2.4.9, if you specified a 'size' value for a non-capped collection, the storage space was pre-allocated. In master, the size value is no longer honored for non-capped collections. This is a regression caused by the changes from SERVER-8412.
2.4.9:
> var myDB = db.getSiblingDB('repro');
> myDB.dropDatabase();
{ "dropped" : "repro", "ok" : 1 }
> myDB.createCollection('sizetest', {size: 10000000});
{ "ok" : 1 }
> myDB.sizetest.stats();
{
"ns" : "repro.sizetest",
"count" : 0,
"size" : 0,
"storageSize" : 10002432,
"numExtents" : 1,
"nindexes" : 1,
"lastExtentSize" : 10002432,
"paddingFactor" : 1,
"systemFlags" : 1,
"userFlags" : 0,
"totalIndexSize" : 8176,
"indexSizes" : {
"_id_" : 8176
},
"ok" : 1
}
master:
> var myDB = db.getSiblingDB('repro');
> myDB.dropDatabase();
{ "dropped" : "repro", "ok" : 1 }
> myDB.createCollection('sizetest', {size: 10000000});
{ "ok" : 1 }
> myDB.sizetest.stats()
{
"ns" : "repro.sizetest",
"count" : 0,
"size" : 0,
"storageSize" : 8192,
"numExtents" : 1,
"nindexes" : 1,
"lastExtentSize" : 8192,
"paddingFactor" : 1,
"systemFlags" : 1,
"userFlags" : 1,
"totalIndexSize" : 8176,
"indexSizes" : {
"_id_" : 8176
},
"ok" : 1
}
