Dgraph v0.4.2 release
Improvements
- Switch to tecbot gorocksdb which allows opening stores as read-only
- Build static binaries for Linux and Mac for ease of use
- Added clients in Python and Java to separate repositories
- Replaced glog with net/tracer which does RPC tracing and exposes HTTP interfaces on /debug/requests and /debug/events for easier debugging.
Others
- Setup TravisCI and Code Coverage.
- Also set up Dgraph wiki at wiki.dgraph.io.
Dgraph v0.3 release
Features
- Dgraph now supports
first: N
argument. Note that N can be negative, to retrieve the last N results.
Example:
{
me(_xid_: m.06pj8) {
film.director.film (first: 10) {
type.object.name.en
film.film.starring (first: -5) {
film.performance.actor {
type.object.name.en
}
}
}
}
}
- Dgraph now supports queries and mutations over binary protocol (Protocol Buffer) via
grpc.io
. We observed significant improvements in the conversion time from Flatbuffers to Protocol Buffer compared to Flatbuffers to JSON. Blog post to follow.
Bug Fixes
- Parse RDF when
_uid_:0xsome-uid
is provided. https://trello.com/c/aHWiDZzA - Handle error output from
rpc.ServeRequest
, and break out of the loop. This bug caused 100% CPU utilization, due to infinite looping in v0.2. - Fixed the bug with timestamps not being monotonically increasing by having the commit module generate the log timestamp, instead of providing one. https://trello.com/c/Qg0eMe6i
Improvements
- Output offending RDF lines if our loader crashes. https://trello.com/c/aFx0Nd0k
- Automatically timeout a query after 1 minute of processing. https://trello.com/c/QXAIThLf
- Value property in an edge is stored as
[]byte
instead ofinterface{}
. This led to latency improvements in the processing of the internalSubgraph
structure.
