This release would not work on v0.7 data directly. Needs backup and reimport.

Features

Server

Client

  • Go client now supports an Unmarshal function which allows unmarshalling the protocol buffer response to a custom struct.
  • Add support for storing and retrieving raw bytes.
  • Cleaner and more intuitive API for doing mutations.

Improvements

  • Move away from RocksDB and get rid of CGO. Start using Badger.
  • Assign uids sequentially.
  • Allow retrieving other children with @groupby.
  • Allow aliases for math expressions.
  • Support filtering using multiple tokens with eq.
  • Better language lists semantics. Issue #1010
  • Add a uid function which can be used for filtering uids at any level.
  • Allow adding @count indexes which allow for faster count comparison queries at the root.
  • Optimisations in how we store Posting List data structure. Store uids separately.
  • Allow specifying a max depth argument for the shortest path.
  • Support for month, day, hour indexes for dateTime datatype.
  • Get rid of lhmap and add an LRU Cache. We don't do Stop the World anymore.

Changes (from v0.7.7)

  • date type is no longer supported as a schema type in Dgraph. You should use dateTime instead.
  • Change of syntax for querying by id.
# Before
{
  me(id: [0x1, 0x2]) {
    ...
  }
}

# Now
{
  me(func: uid(0x1, 0x2)) {
    ...
  }
}
  • Dgraph doesn't fingerprint xids anymore. They are now treated similarly to other edges. So now if you had an xid and you wanted to query by it you would use.
# You need to have an index on xid for calling `eq` function.
{
  me(func: eq(xid, "alice")) {
    ....
  } 
}
  • /admin/backup is now /admin/export. It outputs blank nodes which can now be used to load data into a fresh instance.
  • There is a separate port for http (default 8080) and grpc (default 9080) now.
