Secondary Index Repository

All production secondary index related components (code, design, documentation) live here.

###Setup and Build Instructions

$ mkdir -p $GOPATH/src/github.com/couchbase
$ cd $GOPATH/src/github.com/couchbase
$ git clone [email protected]:couchbase/indexing.git
$ cd indexing/secondary
$ go get -d -v ./...
$ ./build.sh

Note: Following dependencies need to be installed beforehand:

• Protobuf: https://code.google.com/p/protobuf/
• ForestDB: https://github.com/couchbaselabs/forestdb

If build is successful, indexing/secondary/bin will have the binaries for projector and indexer.

####Starting Projector

Projector can be started with below command line options:

bin > ./projector
Usage : ./projector [OPTIONS] <cluster-addr> 
  -adminport="localhost:9999": adminport address
  -loglevel=debug: choose logging level
  -kvaddrs="127.0.0.1:12000": comma separated list of kvaddrs

E.g. projector can be started in trace mode against Couchbase server running with cluster_run mode with the command:

./projector -trace localhost:9000

Projector has a sample test program which can be run using:

go run tools/datapath.go

####Starting Indexer

Projector can be started with below command line options:

bin > ./indexer -h
Usage of ./indexer:
  -loglevel=info|debug|trace
  -projector="http://localhost:9999": Projector Admin Port Address
  -vbuckets=1024: Number of vbuckets configured in Couchbase

E,g. indexer can be started for 8 vbuckets and log level of Info with the below command:

./indexer -vbuckets 8 -log 1

Currently the only entry point for Indexer is tuqtng command line shell. Follow the instructions for setting up the tuqtng project:

https://github.com/couchbaselabs/tuqtng#developers

Instead of the master branch, index-preview branch needs to be built. Rest of the instructions remain the same.

And on the cbq shell, creating an index of type "forestdb" will allocate a new index in the Indexer:

cbq> create index idx1 on default(field1) using forestdb;
