1.1.0 - 2019-09-03

Changed

  • Breaking changes

    • uid schema type: The uid schema type now means a one-to-one relation, not a one-to-many relation as in Dgraph v1.1. To specify a one-to-many relation in Dgraph v1.0, use the [uid] schema type. (#2895, #3173, #2921)

    • _predicate_ is removed from the query language.

    • expand(_all_) only works for nodes with attached type information via the type system. The type system is used to determine the predicates to expand out from a node. (#3262)

    • S * * deletion only works for nodes with attached type information via the type system. The type system is used to determine the predicates to delete from a node. For S * * deletions, only the predicates specified by the type are deleted.

    • HTTP API: The HTTP API has been updated to replace the custom HTTP headers with standard headers.

      • Change /commit endpoint to accept a list of preds for conflict detection. (#3020)
      • Remove custom HTTP Headers, cleanup API. (#3365)
        • The startTs path parameter is now a query parameter startTs for the /query, /mutate, and /commit endpoints.

      • Update HTTP API Content-Type headers. (#3550) (#3532)
        • Queries over HTTP must have the Content-Type header application/graphql+- or application/json.
        • Queries over HTTP with GraphQL Variables (e.g., query queryName($a: string) { ... }) must use the query format via application/json to pass query variables.
        • Mutations over HTTP must have the Content-Type header set to application/rdf for RDF format or application/json for JSON format.
        • Commits over HTTP must have the startTs query parameter along with the JSON map of conflict keys and predicates.

    • Datetime index: Use UTC Hour, Day, Month, Year for datetime comparison. This is a bug fix that may result in different query results for existing queries involving the datetime index. (#3251)

    • Blank node name generation for JSON mutations. For JSON mutations that do not explicitly set the "uid" field, the blank name format has changed to contain randomly generated identifiers. This fixes a bug where two JSON objects within a single mutation are assigned the same blank node. (#3795)

  • Improve hash index. (#2887)

  • Use a stream connection for internal connection health checking. (#2956)

  • Use defer statements to release locks. (#2962)

  • Replace MD5 with SHA-256 in dgraph cert ls. (#3254)

  • Fix use of deprecated function grpc.WithTimeout(). (#3253)

1.0.13 - 2019-03-10

Note: This release supersedes v1.0.12 with bug fixes. If you're running v1.0.12, please upgrade to v1.0.13. It is safe to upgrade in-place without a data export and import.

Fixed

  • Fix Raft panic. (8cb69ea)
  • Log an error instead of an assertion check for SrcUIDs being nil. (691b3b3)

1.0.12 - 2019-03-05

Note: This release requires you to export and re-import data prior to upgrading or rolling back. The underlying data format has been changed.

Added

  • Support gzip compression for gRPC and HTTP requests. (#2843)
  • Restore is available from a full binary backup. This is an enterprise feature licensed under the Dgraph Community License.
  • Strict schema mode via --mutations flag. By default --mutations=allow is set to allow all mutations; --mutations=disallow disables all mutations; --mutations=strict allows mutations only for predicates which are defined in the schema. Fixes #2277.
  • Add dgraph increment tool for debugging and testing. The increment tool queries for the specified predicate (default: counter.val), increments its integer counter value, and mutates the result back to Dgraph. Useful for testing end-to-end txns to verify cluster health. (#2955)
  • Support best-effort queries. This would relax the requirement of linearizible reads. For best-effort queries, Alpha would request timestamps from memory instead of making an outbound request to Zero. (#3071)

Changed

  • Use the new Stream API from Badger instead of Dgraph's Stream framework. (#2852)
  • Discard earlier versions of posting lists. (#2859)
  • Make HTTP JSON response encoding more efficient by operating on a bytes buffer directly. (ae1d9f3)
  • Optimize and refactor facet filtering. (#2829)
  • Show badger.Item meta information in dgraph debug output.
  • Add new option to dgraph debug tool to get a histogram of key and value sizes. (#2844)
  • Add new option to dgraph debug tool to get info from a particular read timestamp.
  • Refactor rebuild index logic. (#2851, #2866)
  • For gRPC clients, schema queries are returned in the Json field. The Schema proto field is deprecated.
  • Simplify design and make tablet moves robust. (#2800)
  • Switch all node IDs to hex in logs (e.g., ID 0xa instead of ID 10), so they are consistent with Raft logs.
  • Refactor reindexing code to only reindex specific tokenizers. (#2948)
  • Introduce group checksums. (#2964, #3085)
  • Return aborted error if commit ts is 0.
  • Reduce number of "ClusterInfoOnly" requests to Zero by making VerifyUid wait for membership information. (#2974)
  • Simplify Raft WAL storage caching. (#3102)
  • Build release binary with Go version 1.11.5.

Removed

  • Remove LRU cache from Alpha for big wins in query latency reduction (5-10x) and mutation throughput (live loading 1.7x faster). Setting --lru_mb is still required but will not have any effect since the cache is removed. The flag will be used later version when LRU cache is introduced within Badger and configurable from Dgraph.
  • Remove --nomutations flag. Its functionality has moved into strict schema mode with the --mutations flag (see Added section).

Fixed

  • Use json.Marshal for strings and blobs. Fixes #2662.
  • Let eq use string "uid" as value. Fixes #2827.
  • Skip empty posting lists in has function.
  • Fix Rollup to pick max update commit ts.
  • Fix a race condition when processing concurrent queries. Fixes #2849.
  • Show an error when running multiple mutation blocks. Fixes #2815.
  • Bring in optimizations and bug fixes over from Badger.
  • Bulk Loader for multi-group (sharded data) clusters writes out per-group schema with only the predicates owned by the group instead of all predicates in the cluster. This fixes an issue where queries made to one group may not return data served by other groups. (#3065)
  • Remove the assert failure in raftwal/storage.go.

1.0.11 - 2018-12-17

Added

  • Support custom tokenizer in bulk loader (#2820)
  • Support JSON data with Dgraph Bulk Loader. (#2799)

Changed

  • Make posting list memory rollup happen right after disk. (#2731)

  • Checking nil values in the equal function (#2769)
  • Optimize query: UID expansion. (#2772)
  • Split membership sync endpoints and remove PurgeTs endpoint. (#2773)
  • Set the Prefix option during iteration. (#2780)
  • Replace Zero's /assignIds?num=10 endpoint with /assign?what=uids&num=10 (see Added section).

Removed

1.0.10 - 2018-11-05

Note: This release requires you to export and re-import data. We have changed the underlying storage format.

Added

  • The Alter endpoint can be protected by an auth token that is set on the Dgraph Alphas via the --auth_token option. This can help prevent accidental schema updates and drop all operations. (#2692)
  • Optimize has function (#2724)
  • Expose the health check API via gRPC. (#2721)

Changed

  • Dgraph is relicensed to Apache 2.0. (#2652)
  • Breaking change. Rename Dgraph Server to Dgraph Alpha to clarify discussions of the Dgraph cluster. The top-level command dgraph server is now dgraph alpha. (#2667)
  • Prometheus metrics have been renamed for consistency for alpha, memory, and lru cache metrics. (#2636, #2670, #2714)
  • The dgraph-converter command is available as the subcommand dgraph conv. (#2635)
  • Updating protobuf version. (#2639)
  • Allow checkpwd to be aliased (#2641)
  • Better control excessive traffic to Dgraph (#2678)
  • Export format now exports on the Alpha receiving the export request. The naming scheme of the export files has been simplified.
  • Improvements to the dgraph debug tool that can be used to inspect the contents of the posting lists directory.
  • Bring in Badger updates (#2697)

Fixed

  • Make raft leader resume probing after snapshot crash (#2707)
  • Breaking change: Create a lot simpler sorted uint64 codec (#2716)
  • Increase the size of applyCh, to give Raft some breathing space. Otherwise, it fails to maintain quorum health.
  • Zero should stream last commit update
  • Send commit timestamps in order (#2687)
  • Query blocks with the same name are no longer allowed.
  • Fix out-of-range values in query parser. (#2690)

1.0.9 - 2018-10-02

Added

  • This version switches Badger Options to reasonable settings for p and w directories. This removes the need to expose --badger.options option and removes the none option from --badger.vlog. (#2605)
  • Add support for ignoring parse errors in bulk loader with the option --ignore_error. (#2599)
  • Introduction of new command dgraph cert to simplify initial TLS setup. See TLS configuration docs for more info.
  • Add expand(_forward_) and expand(_reverse_) to GraphQL+- query language. If _forward_ is passed as an argument to expand(), all predicates at that level (minus any reverse predicates) are retrieved. If _reverse_ is passed as an argument to expand(), only the reverse predicates are retrieved.

Changed

  • Rename intern pkg to pb (#2608)

Fixed

  • Remove LinRead map logic from Dgraph (#2570)
  • Sanity length check for facets mostly.
  • Make has function correct w.r.t. transactions (#2585)
  • Increase the snapshot calculation interval, while decreasing the min number of entries required; so we take snapshots even when there's little activity.
  • Convert an assert during DropAll to inf retry. (#2578)
  • Fix a bug which caused all transactions to abort if --expand_edge was set to false. Fixes #2547.
  • Set the Applied index in Raft directly, so it does not pick up an index older than the snapshot. Ensure that it is in sync with the Applied watermark. Fixes #2581.
  • Pull in Badger updates. This also fixes the Unable to find log file, retry error.
  • Improve efficiency of readonly transactions by reusing the same read ts (#2604)
  • Fix a bug in Raft.Run loop. (#2606)
  • Fix a few issues regarding snapshot.Index for raft.Cfg.Applied. Do not overwrite any existing data when apply txn commits. Do not let CreateSnapshot fail.
  • Consider all future versions of the key as well, when deciding whether to write a key or not during txn commits. Otherwise, we'll end up in an endless loop of trying to write a stale key but failing to do so.
  • When testing inequality value vars with non-matching values, the response was sent as an error although it should return empty result if the query has correct syntax. (#2611)
  • Switch traces to glogs in worker/export.go (#2614)
  • Improve error handling for dgraph live for errors when processing RDF and schema files. (#2596)
  • Fix task conversion from bool to int that used uint32 (#2621)
  • Fix expand(_all_) in recurse queries (#2600).
  • Add language aliases for broader support for full text indices. (#2602)

1.0.8 - 2018-08-29

Added

  • Introduce a new /assignIds HTTP endpoint in Zero, so users can allocate UIDs to nodes externally.
  • Add a new tool which retrieves and increments a counter by 1 transactionally. This can be used to test the sanity of Dgraph cluster.

Changed

  • This version introduces tracking of a few anonymous metrics to measure Dgraph adoption (#2554). These metrics do not contain any specifically identifying information about the user, so most users can leave it on. This can be turned off by setting --telemetry=false flag if needed in Dgraph Zero.

Fixed

  • Correctly handle a list of type geo in json (#2482, #2485).
  • Fix the graceful shutdown of Dgraph server, so a single Ctrl+C would now suffice to stop it.
  • Fix various deadlocks in Dgraph and set ConfState in Raft correctly (#2548).
  • Significantly decrease the number of transaction aborts by using SPO as key for entity to entity connections. (#2556).
  • Do not print error while sending Raft message by default. No action needs to be taken by the user, so it is set to V(3) level.

1.0.7 - 2018-08-10

Changed

  • Set the --conc flag in live loader default to 1, as a temporary fix to avoid tons of aborts.

Fixed

  • All Oracle delta streams are applied via Raft proposals. This deals better with network partition like edge-cases. #2463
  • Fix deadlock in 10-node cluster convergence. Fixes #2286.
  • Make ReadIndex work safely. #2469
  • Simplify snapshots, leader now calculates and proposes snapshots to the group. #2475.

  • Bug fix in Badger, to stop panics when exporting.
  • Use PreVote to avoid leader change on a node join.
  • Fix a long-standing bug where raft.Step was being called via goroutines. It is now called serially.

  • Fix bugs in Bulk loader. #2449
  • Posting List and Raft bug fixes. #2457

Changed

  • Pull in Badger v1.5.2.
  • Raft storage is now done entirely via Badger. This reduces RAM consumption by previously used MemoryStorage. #2433
  • Trace how node.Run loop performs.
  • Allow tweaking Badger options.

Note: This change modifies some flag names. In particular, Badger options are now exposed via flags named with --badger. prefix.

The latest release has a lot of breaking changes but also brings powerful features like Transactions, support for CJK and custom tokenization.

Added

  • Dgraph adds support for distributed ACID transactions (a blog post is in works). Transactions can be done via the Go, Java or HTTP clients (JS client coming). See docs here.
  • Support for Indexing via Custom tokenizers.
  • Support for CJK languages in the full-text index.

Changed

Running Dgraph

  • We have consolidated all the server, zero, live/bulk-loader binaries into a single dgraph binary for convenience. Instructions for running Dgraph can be found in the docs.
  • For Dgraph server, Raft ids can be assigned automatically. A user can optionally still specify an ID, via --idx flag.
  • --peer flag which was used to specify another Zero instance’s IP address is being replaced by --zero flag to indicate the address corresponds to Dgraph zero.
  • port, grpc_port and worker_port flags have been removed from Dgraph server and Zero. The ports are:
  • Internal Grpc: 7080
  • HTTP: 8080
  • External Grpc: 9080 (Dgraph server only)

Users can set port_offset flag, to modify these fixed ports.

Queries

  • Queries, mutations and schema updates are done through separate endpoints. Queries can no longer have a mutation block.
  • Queries can be done via Query Grpc endpoint (it was called Run before) or the /query HTTP handler.
  • _uid_ is renamed to uid. So queries now need to request for uid. Example
{
  bladerunner(func: eq(name@en, "Blade Runner")) {
    uid
    name@en
  }
}
  • Facets response structure has been modified and is a lot flatter. Facet key is now predicate|facet_name. Examples for Go client and HTTP.
  • Query latency is now returned as numeric (ns) instead of string.
  • Recurse is now a directive. So queries with recurse keyword at root won't work anymore.
  • Syntax for count at root has changed. You need to ask for count(uid), instead of count().

Mutations

  • Mutations can only be done via Mutate Grpc endpoint or via /mutate HTTP handler.
  • Mutate Grpc endpoint can be used to set/ delete JSON, or set/ delete a list of N-Quads and set/ delete raw RDF strings.
  • Mutation blocks don't require the mutation keyword anymore. Here is an example of the new syntax.
{
  set {
    <name> <is> <something> .
    <hometown> <is> "San Francisco" .
  }
}
  • Upsert directive and mutation variables go away. Both these functionalities can now easily be achieved via transactions.

Schema

  • <*> <pred> <*> operations, that is deleting a predicate can't be done via mutations anymore. They need to be done via Alter Grpc endpoint or via the /alter HTTP handler.
  • Drop all is now done via Alter.
  • Schema updates are now done via Alter Grpc endpoint or via /alter HTTP handler.

Go client

  • Query Grpc endpoint returns response in JSON under Json field instead of protocol buffer. client.Unmarshal method also goes away from the Go client. Users can use json.Unmarshal for unmarshalling the response.
  • Response for predicate of type geo can be unmarshalled into a struct. Example here.
  • Node and Edge structs go away along with the SetValue... methods. We recommend using SetJson and DeleteJson fields to do mutations.
  • Examples of how to use transactions using the client can be found at https://dgraph.io/docs/clients/#go.

Removed

  • Embedded dgraph goes away. We haven’t seen much usage of this feature. And it adds unnecessary maintenance overhead to the code.
  • Dgraph live no longer stores external ids. And hence the xid flag is gone.
