Cloning wind data from one MongoDB instance to another
|
|
------------------------------------------------------
|
|
|
|
10200: MongoDB "dev" instance
|
|
10201: MongoDB "test" instance
|
|
10202: MontoDB "prod" instance
|
|
|
|
connect to the mongo shell:
|
|
e.g. /opt/mongodb/bin/mongo --port 10202
|
|
|
|
typical commands:
|
|
show dbs displays all the databases on the server you are connected to
|
|
use db_name switches to db_name on the same server
|
|
show collections displays a list of all the collections in the current database
|
|
|
|
|
|
First, export the WIND_TRACKS collection from one database. For example...
|
|
|
|
/opt/mongodb/bin/mongoexport --port 10202 -d winddb -c WIND_TRACKS > /tmp/wind-tracks-dev.json
|
|
|
|
or with an additional query parameter if only want to export the wind of a specific race
|
|
|
|
/opt/mongodb/bin/mongoexport --port 10202 -d winddb -c WIND_TRACKS -q "{ 'EVENT_NAME': /Arenal Training Camps Regatta 2012/, 'RACE_NAME': /Laser/}" > /tmp/wind-tracks-dev.json
|
|
|
|
To import the resulting JSON file into the DB instance call:
|
|
/opt/mongodb/bin/mongoimport --port 10201 -d winddb -c WIND_TRACKS /tmp/wind-tracks-dev.json
|
|
|
|
|
|
