Maximum MongoDB query memory size (This limitation is only for 3.2 server version) 40 MB: Maximum execution time for MongoDB operations: 30s: Idle connection timeout for server side connection closure* 30 minutes
Moreover, In MongoDB, you can use the limit() method to specify a maximum number of documents for a cursor to return. When you query a collection using the db.collection.find() method, you can append limit() to specify the limit. Example. First let's do a query without a limit (so we can see how many documents are returned): Without a Limit And, BSON Document Size¶. The maximum BSON document size is 16 megabytes. The maximum document size helps ensure that a single document cannot use excessive amount of RAM or, during transmission, excessive amount of bandwidth. To store documents larger than the maximum size, MongoDB provides the GridFS API. Just so, MongoDB evaluates non-$wherequery operations before $whereexpressions and non-$wherequery statements may use an index. A much better performance is to store the length of the string as another field and then you can index or search on it; applying $wherewill be much slower compared to that. Thereof, There can be no more than 32 fields in a compound index. You cannot combine the $text query, which requires a special text index, with a query operator that requires a different type of special index. For example you cannot combine $text query with the $near operator.

Can a focal length zoom lens change its focal length?
To many people, this focal length zoom lens is a telephoto lens, since you can “zoom in” on a subject. But in simplest terms, a focal length zoom lens can change focal lengths, while the other cannot. This focal length zoom lens can adjust its range to be wide or long telephoto.
How to calculate stride length and step length?
How to calculate your step and stride length Using the tape measure and the chalk (outside) or the masking tape (inside), measure and mark off a specific distance, such as 20 feet. Start walking about 10 feet before one of the marks to get up to speed in your natural walk. When you hit the first mark, start counting your steps, stopping your count when you hit the second mark.

How to adjust vxr 31.5 " draw length and arrow length?
Also changing the top cam top hats will have a greater effect on the tune than switching the bottom. So for larger tears starts with the top cam. For smaller movements adjust the bottom. 29.5" Draw Length, 30" Arrow Length. OR Archer. I heard this and that was my first move, definitely tightened it up but did not fully correct.
Is the planck length the minimum possible length?
The Planck length is not the smallest possible length. It is just the length scale where quantum gravitational effects are expected to be large. The Planck length is not the smallest possible length.
Is a planck length really the smallest length?
Planck length might be the smallest length we will ever be able to measure, but that does not mean it is an absolutely the smallest length . It is rather the smallest possible size of a particle as we understand it now. To see a structure of any object, we must shoot it with some particles of certain energy.
Which is larger delay length or coherence length?
The criterion which is usually used is that the delay length must be larger than the coherence length, and the latter is derived from the (measured) linewidth itself. This is correct for white frequency noise, but not in situations with higher (e.g. 1 / f) low-frequency noise [5], as can occur e.g. for narrow-linewidth fiber lasers .
How is the length of dot11 _ ssid _ max _ length determined?
DOT11_SSID_MAX_LENGTH is set to 32. The SSID that is specified by the ucSSID member is not a null-terminated ASCII string. The length of the SSID is determined by the uSSIDLength member. A wildcard SSID is an SSID whose uSSIDLength member is set to zero.
How is datum length and pitch length determined?
When the pulley diameters differ, the arc of contact is less than 180 degrees on the smaller pulley and greater than 180 degrees on the larger pulley. In this case, the formula for belt datum length requires determining the arc of contact on each pulley, as well as the length of belt between pulleys on both the top and bottom.
How did the length of a meter get its length?
PALCA: A meter would be defined as one 10-millionth of the distance from the North Pole to the equator - trouble is, no one knew exactly what was the distance from the North Pole to the equator. So in 1792, an expedition was mounted.
How to calculate scale length and scale length?
Scale ratio 1:200 Scale length : 5 cm Real length : 5 cm × 200 ÷ 1 = 1000 cm Door actual width at scale 1:50 On the building plan the width of the front door is 18.6 mm. and the scale of the plan is 1:50, what is the actual width of that door ? First, we convert the unit from millimeter to centimeter. 18.6 mm = 18.8 ÷ 10 = 1.86 cm

Which is greater extension length or rail length?
Extended stroke: The extension length is greater than the rail length. (Also referred to as “over-extension.”) For most extended stroke slides, the extension length can be up to 150 percent of the rail length. These designs often require an intermediate element.
What's the difference between embedment length and length?
Typically, embedment length is referred to as the distance the rebar is inserted into the concrete on a particular placement. Often, when you are building a concrete structure of some kind, you don’t place all of the concrete at once. You may place the footing, for example, and then place additional concrete above that, creating a cold joint.
Where do you measure arm length and shoulder length?
The Shoulder to Waist measurement is a vertical measurement that should be taken from the top of your shoulder (where the shoulder seam of a shirt usually is) down to where you took your Waist measurement. The Arm Length measurement measures the length of your desired sleeve, based on which sleeve length option you choose for a particular design.
