// INDEXES TO SUPPORT COUCHDB RICH QUERIES
|
||||
//
|
||||
// Indexes in CouchDB are required in order to make JSON queries efficient and are required for
|
||||
// any JSON query with a sort. Indexes may be packaged alongside
|
||||
// chaincode in a META-INF/statedb/couchdb/indexes directory. Each index must be defined in its own
|
||||
// text file with extension *.json with the index definition formatted in JSON following the
|
||||
// CouchDB index JSON syntax as documented at:
|
||||
// http://docs.couchdb.org/en/2.3.1/api/database/find.html#db-index
|
||||
//
|
||||
// This asset transfer ledger example chaincode demonstrates a packaged
|
||||
// index which you can find in META-INF/statedb/couchdb/indexes/indexOwner.json.
|
||||
//
|
||||
// If you have access to the your peer's CouchDB state database in a development environment,
|
||||
// you may want to iteratively test various indexes in support of your chaincode queries. You
|
||||
// can use the CouchDB Fauxton interface or a command line curl utility to create and update
|
||||
// indexes. Then once you finalize an index, include the index definition alongside your
|
||||
// chaincode in the META-INF/statedb/couchdb/indexes directory, for packaging and deployment
|
||||
// to managed environments.
|
||||
//
|
||||
// In the examples below you can find index definitions that support asset transfer ledger
|
||||
// chaincode queries, along with the syntax that you can use in development environments
|
||||
// to create the indexes in the CouchDB Fauxton interface or a curl command line utility.
|
||||
//
|
||||
|
||||
// Index for docType, owner.
|
||||
//
|
||||
// Example curl command line to define index in the CouchDB channel_chaincode database
|
||||
// curl -i -X POST -H "Content-Type: application/json" -d "{\"index\":{\"fields\":[\"docType\",\"owner\"]},\"name\":\"indexOwner\",\"ddoc\":\"indexOwnerDoc\",\"type\":\"json\"}" http://hostname:port/myc1_assets/_index
|
||||
//
|
||||
|
||||
// Index for docType, owner, size (descending order).
|

// Example curl command line to define index in the CouchDB channel_chaincode database
