MongoDB: When is an upgrade finished?

0 votes
152 views

I have been studying the upgrade instructions and this important point is left out.

https://docs.mongodb.com/manual/release-notes/3.2-upgrade/https://docs.mongodb.com/manual/release-notes/3.0-upgrade/https://docs.mongodb.com/manual/release-notes/2.6-upgrade/

I have to do a multi-stage upgrade from 2.4 to 3.2. The instructions for each upgrade stage is a binary-compatible drop-in  upgrade. The instructions say to:Download binaries Shut down your mongod instance Replace the existing binary with the new mongod binaryRestart mongod

What they do not say is how you will know that the upgrade has completed. I think its pretty obvious that you cant do...service mongodb start && service mongodb stop...and then move to the next stage of the upgrade.

How do you know when your upgrade is complete? (I am expecting there to be a terminal command I can use to check on the progress/success.)

MongoDB: when compress data, I want to get the block's data type to do more efficient compress algo?

I want compress the data stored in column more efficient, because mydata is timeseries of stock or future price.
Most of them is similar, so I thought I could compress the price data(float, uint64, int) more efficient than zlib,like what infobright do.

Could any one tell me how to compress the column more efficient or could I get the blocks data type when I write the compress plug.

db.test.find()

3.increment the value with negative fractional value

db.test.update({},{$inc:{"qty":-0.608}})
