API Reference

List all index schemas

GET /index

Is equivalent to GET /schema and returns the same response.

List index schema

GET /index/<index-name>

Returns the schema of the specified index in JSON.

curl -XGET localhost:10101/index/user
{
    "fields": [
        {
            "name": "event",
            "options": {
                "keys": false,
                "timeQuantum": "YMD",
                "type": "time"
            }
        }
    ],
    "name": "user",
    "options": {
        "keys": false,
        "trackExistence": true
    }
}

Create index

POST /index/<index-name>

Creates an index with the given name.

The request payload is in JSON, and may contain the options field. The options field is a JSON object with the following options:

curl -XPOST localhost:10101/index/user -d '{"options":{"keys":true}}'
{"success":true}

Remove index

DELETE /index/index-name

Removes the given index.

curl -XDELETE localhost:10101/index/user
{"success":true}

Query index

POST /index/<index-name>/query

Sends a query to the Pilosa server with the given index. The request body is UTF-8 encoded text and response body is in JSON by default.

curl localhost:10101/index/user/query \
     -X POST \
     -d 'Row(language=5)'
{
    "results": [
        {
            "attrs": {},
            "columns": [
                100
            ]
        }
    ]
}

In order to send protobuf binaries in the request and response, set Content-Type and Accept headers to: application/x-protobuf.

The response doesn’t include column attributes by default. To return them, set the columnAttrs query argument to true.

The query is executed for all shards by default. To use specified shards only, set the shards query argument to a comma-separated list of slice indices.

curl "localhost:10101/index/user/query?columnAttrs=true&shards=0,1" \
     -X POST \
     -d 'Row(language=5)'
{
    "columnAttrs": [
        {
            "attrs": {
                "name": "Klingon"
            },
            "id": 100
        }
    ],
    "results": [
        {
            "attrs": {},
            "columns": [
                100
            ]
        }
    ]
}

By default, all bits and attributes (for Row queries only) are returned. In order to suppress returning bits, set excludeBits query argument to true; to suppress returning attributes, set excludeAttrs query argument to true.

Import Data

POST /index/<index-name>/field/<field-name>/import

Supports high-rate data ingest to a particular shard of a particular field. The official client libraries use this endpoint for their import functionality - it is not usually necessary to use this endpoint directly. See the documentation for imports for Go, Java, and Python.

The request payload is protobuf encoded with the following schema. The RowKeys and/or ColumnKeys fields are used if the pilosa field or index are configured for keys respectively. Otherwise, the RowIDs and ColumnIDs fields are used. They must have the same number of items, and each index into those two lists represents a particular bit to be set. Timestamps are optional, but if they exist must also contain the same number of items as rows and columns. The column IDs must all be in the shard specified in the request.

message ImportRequest {
	string Index = 1;
	string Field = 2;
	uint64 Shard = 3;
	repeated uint64 RowIDs = 4;
	repeated uint64 ColumnIDs = 5;
	repeated string RowKeys = 7;
	repeated string ColumnKeys = 8;
	repeated int64 Timestamps = 6;
}

Create field

POST /index/<index-name>/field/<field-name>

Creates a field in the given index with the given name.

The request payload is in JSON, and may contain the options field. The options field is a JSON object which must contain a type:

Valid types and correspondonding options are listed below:

The following example creates an int field called “quantity” capable of storing values from -1000 to 2000:

curl localhost:10101/index/user/field/quantity \
     -X POST \
     -d '{"options": {"type": "int", "min": -1000, "max":2000}}'
{"success":true}

Integer fields are stored as n-bit range-encoded values. Pilosa supports 63-bit, signed integers with values between min and max.

curl localhost:10101/index/user/field/language -X POST
{"success":true}
curl localhost:10101/index/repository/field/stats \
    -X POST \
    -d '{"fields": [{"name": "pullrequests", "type": "int", "min": 0, "max": 1000000}]}'
{"success":true}

Remove field

DELETE /index/<index-name>/field/<field-name>

Removes the given field.

curl -XDELETE localhost:10101/index/user/field/language
{"success":true}

List all index schemas

GET /schema

Returns the schema of all indexes in JSON.

curl -XGET localhost:10101/index
{
    "indexes": [
        {
            "fields": [
                {
                    "name": "event",
                    "options": {
                        "keys": false,
                        "timeQuantum": "YMD",
                        "type": "time"
                    }
                },
                {
                    "name": "language",
                    "options": {
                        "cacheSize": 50000,
                        "cacheType": "ranked",
                        "keys": false,
                        "type": "set"
                    }
                }
            ],
            "name": "user",
            "options": {
                "keys": false,
                "trackExistence": true
            }
        }
    ]
}

Get version

GET /version

Returns the version of the Pilosa server.

curl -XGET localhost:10101/version
{"version":"v0.6.0"}

Get status

GET /status

Returns the status of the cluster.

curl -XGET localhost:10101/status
{
    "localID": "d3369125-29d8-4305-a351-b4474d14a542",
    "nodes": [
        {
            "id": "d3369125-29d8-4305-a351-b4474d14a542",
            "isCoordinator": true,
            "uri": {
                "host": "localhost",
                "port": 10101,
                "scheme": "http"
            }
        }
    ],
    "state": "NORMAL"
}

Recalculate Caches

POST /recalculate-caches

Recalculates the caches on demand. The cache is recalculated every 10 seconds by default. This endpoint can be used to recalculate the cache before the 10 second interval. This should probably only be used in integration tests and not in a typical production workflow. Note that in a multi-node cluster, the cache is only recalculated on the node that receives the request.

curl -XPOST localhost:10101/recalculate-caches

Response: 204 No Content
