In order to follow REST a bit more carefully, all write operations
should go through a POST in the future. We still allow read operations
through either GET or POST (similar to the Graphite /render endpoint),
but write operations will trigger a returned warning as part of the JSON
response and will eventually return an error.
Also updates the Golang client libraries to always use POST instead of
GET.
Fixes#6290.
The series keys within a tag set were previously not sorted which would
cause the output to be non-deterministic. This sorts the output series
by their keys so it has a consistent output especially when using
limits.
Fixes#3166.
The deprecated message is now attached to a new attribute returned with
the results. This message can then be read by clients to warn a user
about upcoming changes to the query engine.
The `influx` client has already been modified to read this message and
print it out for every format except CSV.
The first warning message is a deprecated message about removing `IF NOT
EXISTS` from `CREATE DATABASE`.
The message will also be printed to the server log.
Fixes#5707.
If no chunking was requested by the user, the co-ordinating node buffers all
results in RAM before emitting a single result. However buffering was not
merging results for rows which had data for the same series. This change fixes this.
Fixes issue #3242.
Any literal values in a math query e.g. the '2' in 'value * 2' are
stored as float64, so all other values must be cast to this type. This
does mean that precision may be lost if the integer values are greater
than 2^53.
With this change, the query engine code gathers information about
shards and tagsets by working with individual shards, collating the
information, and returning that to the client. It does not assume that any
particular shard is local, and accesses all shards through abstracted
Mappers, of which there are two types -- a Mapper type for Raw queries
and a second type for Aggregate queries. There are corresponding
Executors for each type of Mapper, but both types of Executors share the
same interface.
