Advantages of Distributed database

This section will provide a detailed reference and examples for the Pilosa Query Language (PQL). All PQL queries operate on a single index and are passed to Pilosa through the /index/INDEX_NAME/query endpoint. You may pass multiple PQL queries in a single request by simply concatenating the queries together – a space is not needed. The results format is always:

{"results":[...]}

There will be one item in the results array for each PQL query in the request. The type of each item in the array will depend on the type of query – each query in the reference below lists its result type.

Conventions

  • Angle Brackets <> denote required arguments
  • Square Brackets [] denote optional arguments
  • UPPER_CASE denotes a descriptor that will need to be filled in with a concrete value (e.g. ATTR_NAMESTRING)
Examples

Before running any of the example queries below, follow the instructions in the Getting Started section to set up an index and fields, and to populate them with some data.

The examples just show the PQL quer(ies) needed – to run the query Set(10, stargazer=1) against a server using curl, you would:

curl localhost:10101/index/repository/query \
     -X POST \
     -d 'Set(10, stargazer=1)'
{"results":[true]}
