Sync shard metadata, copies sharding metadata from one cluster to another.

java -cp mongo-util.jar com.mongodb.shardsync.ShardConfigSyncApp \
    -s mongodb:https://admin:mypassword@source:27017/?authSource=admin \
    -d mongodb:https://destination1:27017 \
    -f db1 -f db2 \
    -m sh_0|shard_A -m sh_1|shard_A -m sh_2|shard_B -m sh_3|shard_B \
    -p /Users/mh/go/src/github.com/10gen/mongomirror/build/mongomirror \
    -dropDestinationCollectionsIfExisting \
    -syncMetadata

Run mongomirror process for each shard

java -cp mongo-util.jar com.mongodb.shardsync.ShardConfigSyncApp \
    -s mongodb:https://admin:mypassword@source:27017/?authSource=admin \
    -d mongodb:https://destination1:27017 \
    -f db1 -f db2 \
    -m sh_0|shard_A -m sh_1|shard_A -m sh_2|shard_B -m sh_3|shard_B \
    -p /Users/mh/go/src/github.com/10gen/mongomirror/build/mongomirror \
    -dropDestinationCollectionsIfExisting \
    -mongomirror

This tool will filter the operations captured to only the essential operations, e.g. internal ops are removed and replies are removed from the resulting BSON.

This will also transcode 2010 opcodes to 2004 opcodes, which is useful when capturing sharded operations between a mongos and a mongod. Additionally, mongoreplay currently does not properly handle $query commands which will be sent in certain cases, e.g. when a non-default ReadPreference is specified.

Also supports limiting the number of operations (-l) and filtering fields from updates.

Download:

wget -O mongo-util.jar https://github.com/mhelmstetter/mongo-util/blob/master/bin/mongo-util.jar?raw=true

Run:

java -cp mongo-util.jar com.mongodb.mongoreplay.MongoReplayFilter -f record041020185.bson

The output file will be written with the same name + .FILTERED.

Similar to the mongoreplay utility, this encorporates some of the "hacks" implemented by MongoReplayFilter, and directly play the traffic to the desitination cluster.
