# API Reference

The Tilores API is highly customizable. The reference therefore only focusses on the basic and default API.

The disassemble mutation helps you to remove records and/or edges.

Example request:

mutation {
  disassemble(input: {
    edges: [
      {
        a: "<uuid-record-a>"
        b: "<uuid-record-b>"
      }
    ]
    recordIDs: [
      "<uuid-record-c>"
      "<uuid-record-d>"
    ]
    createConnectionBan: false
    meta: {
      user: "<user-name>"
      reason: "some reason"
    }
  }) {
    triggered
  }
}

When providing edges, all edges between the two records will be removed, independent of their type. The records itself will not be removed.

When providing recordIDs, the records as well as their edges will be removed.

You must at least provide one record ID or one edge. You can at the same time provide edges and record IDs. If an edge or a record is the only connecting link between two (or more) parts of an entity, then the entity will be split into multiple entities.

All record IDs mentioned in edges and recordIDs must belong to the same entity.

When an entity was split into multiple entities and the setting createConnectionBan is true (default is false), then this will prevent the newly created entities from ever merging again. Any record that would merge these entities will be dropped in that case. Connection bans will be inherited, meaning, that when entity A, which has a connection ban to entity B, is merged into entity C, then C afterwards also will have a connection ban towards B. The same is true for splitting A.

The user and the reason from the optional meta block, will currently only show up in the logs and should explain why and when a record or an edge was removed.

Example response:

{
  "data": {
    "disassemble": {
      "triggered": true
    }
  }
}

deletedEdges and deletedRecords represent the number of removed edges and records. deletedEdges may have a higher number than the edges explicitly removed.

entityIDs lists all IDs of the resulting entities. If the disassemble caused the entity to be deleted, this entry will be empty. If the disassemble caused the entity to be updated, it will contain exactly one entry. And otherwise it will contain at least two entries.

If an error occurs during the disassemble, it will first retry it internally again. If this fails again, it will schedule the removal for a later retry and return with an error message to the API user. Usually, the API user can ignore that specific error - it will eventually perform the disassemble.

The removeConnectionBan removes an existing connection ban between two or more entities.

Example request:

mutation {
  removeConnectionBan(input: {
    reference: "<uuid>"
    entityID: "<entity-id-a>"
    others: [
      "<entity-id-b>"
      "<entity-id-c>"
    ]
    meta: {
      user: "<user-name>"
      reason: "some reason"
    }
  }) {
    removed
  }
}

The reference must be a unique ID, that can be reused if the same request needs to be processed again later due to a previous error.

The connection ban will always be removed between entityID and each entity ID from others. It will not affect possible connection bans in between the others entities.

The user and the reason from the meta block, will currently only show up in the logs and should explain why and when a record or an edge was removed.

Example response:

{
  "data": {
    "removeConnectionBan": {
      "removed": true
    }
  }
}

Unless there was an error, the removed field will always return true.

If an error occurs during the removal, it will first retry it internally again. If this fails again, it will schedule the removal for a later retry and return with an error message to the API user. Usually, the API user can ignore that specific error - it will eventually perform the connection ban removal.

The submit mutation adds the provided records into Tilores.

Example request:

mutation {
  submit(input: {
    records: [
      {
        id: "my-id",
        myCustomField: "some-value"
      }
    ]
  }) {
    recordsAdded
  }
}

The structure for each value in records is dependent on your customized schema for the RecordInput.

Multiple records submitted in a single mutation will be automatically connected with each other using a STATIC edge. This is independent from the matching rules.

Example response:

{
  "data": {
    "submit": {
      "recordsAdded": 1
    }
  }
}

recordsAdded will just return the number of records that have successfully be submitted into Tilores.

The entity query will search for the provided entity ID and return it.

Example request:

{
  entity(input: {
    id: "<uuid-entity>"
  }){
    entity {
      id
      records {
        id
        myCustomField
      }
      edges
      duplicates
      hits
    }
  }
}

The id is the entity ID to search for.

Example response:

{
  "data": {
    "entity": {
      "id": "<uuid-entity>",
      "records": [
        {
          "id": "<record-id-a>",
          "myCustomField": "some value"
        },
        {
          "id": "<record-id-b>",
          "myCustomField": "some other value"
        },
        {
          "id": "<record-id-c>",
          "myCustomField": "some value"
        }
      ],
      "edges": [
        "<record-id-a>:<record-id-b>:STATIC",
        "<record-id-a>:<record-id-b>:R1EXACT"
      ],
      "duplicates": {
        "<record-id-a>": [
          "<record-id-c>"
        ]
      },
      "hits": {}
    }
  }
}

If an entity with the provided ID exists, then this entity will be returned in the entity field. Otherwise this field will be null.

Each entity has the following fields:

id is the entity ID.

records is a list of all records of that entity. The queryable fields depend on the Record from your custom schema.

edges lists all edges in that entity, which represents how the records are connected with each other.

duplicates lists all duplicates of that entry. When not using rule groups the key of that map will be the record ID of the original and the entries will be the record IDs of the duplicates. When using rule groups, the key will additionally be prefixed with the ID of the rule group and a colon (<rule-group-id>:<record-id-a>) and the values stay unchanged. In that case one record ID of a duplicate can be present in the values of multiple keys.

The hits will always be empty for an entity search.

recordInsights provides filtering, statistics and aggregation on the entity records. Refer to record insights for more details.

edgeInsights provides statistics and aggregation on the entities edges and duplicates. Refer to edge insights for more details.

The search query will search for the provided values using the search rules.

Example request:

{
  search(input: {
    parameters: {
    	myCustomField: "some-value"
    }
  }) {
    entities {
      id
      records {
        id
        myCustomField
      }
      edges
      duplicates
      hits
    }
  }
}

The parameters define your custom search parameters as they are defined using the SearchParams type.

Example response:

{
  "data": {
    "entities": [
      {
        "id": "<uuid-entity>",
        "records": [
          {
            "id": "<record-id-a>",
            "myCustomField": "some value"
          },
          {
            "id": "<record-id-b>",
            "myCustomField": "some other value"
          },
          {
            "id": "<record-id-c>",
            "myCustomField": "some value"
          }
        ],
        "edges": [
          "<record-id-a>:<record-id-b>:STATIC",
          "<record-id-a>:<record-id-b>:R1EXACT"
        ],
        "duplicates": {
          "<record-id-a>": [
            "<record-id-c>"
          ]
        },
        "hits": {
          "<record-id-a>": [
            "R1EXACT"
          ]
        }
      }
    ]
  }
}

entities is either an empty list or a list with all the found entities. Their structure equals the one described in query: entity, except that for the hits you receive a list of record IDs that fit to the search and the rule ID with which they were found.

Not yet integrated into the GraphQL API, but also very helpful when it comes to observing changes in entities is the entity event stream. This stream is provided via AWS SQS or AWS Kinesis based on what is selected during deployment. Requires an IAM user to access the data.

Every single data change in Tilores is published via that stream. The following events are currently available.

The create event will be published, when an entity was newly created, meaning a record was submitted, but was not attached to an existing entity.

Example:

{
  "type": "CREATE",
  "timestamp": "2022-01-01T00:00:00.000000000Z",
  "data": {
    "entities": [{
      "id": "<new-entity-id>",
      "recordIDs": ["<new-record-id>"],
      "obsoleteRecordIDs": []
    }],
    "obsoleteEntities": []
  }
}

The update event will be published when a record is submitted and was matched with exactly one existing entity.

Example:

{
  "type": "UPDATE",
  "timestamp": "2022-01-01T00:00:00.000000000Z",
  "data": {
    "entities": [{
      "id": "<entity-id>",
      "recordIDs": ["<new-record-id>","<record-id>"],
      "obsoleteRecordIDs": []
    }],
    "obsoleteEntities": []
  }
}

The merge event will be published when a record is submitted and was matched with more than one existing entity, resulting in all of these entities being merged.

Example:

{
  "type": "MERGE",
  "timestamp": "2022-01-01T00:00:00.000000000Z",
  "data": {
    "entities": [{
      "id": "<entity-id-a>",
      "recordIDs": ["<record-id-a>","<record-id-b>","<new-record-id>"],
      "obsoleteRecordIDs": []
    }],
    "obsoleteEntities": [
      {
        "id": "<entity-id-b>",
        "recordIDs": [],
        "obsoleteRecordIDs": []
      }
    ]
  }
}

The split event will be published when an edge or a record that connected at least two parts of an entity was deleted, resulting in at least two new entities.

Example:

{
  "type": "SPLIT",
  "timestamp": "2022-01-01T00:00:00.000000000Z",
  "data": {
    "entities": [
      {
        "id": "<entity-id-a>",
        "recordIDs": ["<record-id-a>"],
        "obsoleteRecordIDs": ["<record-id-a-b>"]
      },
      {
        "id": "<entity-id-b>",
        "recordIDs": ["<record-id-b>"],
        "obsoleteRecordIDs": []
      }
    ],
    "obsoleteEntities": []
  }
}

The delete event will be published when all records from an entity have been removed.

Example:

{
  "type": "DELETE",
  "timestamp": "2022-01-01T00:00:00.000000000Z",
  "data": {
    "entities": [],
    "obsoleteEntities": [
      {
        "id": "<entity-id>",
        "recordIDs": [],
        "obsoleteRecordIDs": ["<deleted-record-id>"]
      }
    ]
  }
}

Provides filtering, statistics and aggregation on the entity records. This is available on the entity type.

• filter(conditions: [FilterCondition!]!): RecordInsights!: Returns a new RecordInsights object that only contains the records for which the FilterCondition applies.

  • equals: ensures that the fields value is equal to the provided value.
  • isNull: ensures that the field must have a null value.
  • startsWith: ensures that the fields value starts with the provided text. Using startsWith on non-string fields will convert them into strings first. This may lead to unexpected, but correct results.
  • endsWith: ensures that the fields value ends with the provided text. Using endsWith on non-string fields will convert them into strings first. This may lead to unexpected, but correct results.
  • likeRegex: ensures that the fields value matches the provided regular expression. Using likeRegex on non-string fields will convert them into strings first. This may lead to unexpected, but correct results.
  • lessThan: ensures that the fields value is less than the provided value. Using lessThan on non-numeric fields will raise an error. This may lead to unexpected, but correct results.
  • lessEquals: ensures that the fields value is less than or equals the provided value. Using lessEquals on non-numeric fields will raise an error.
  • greaterThan: ensures that the fields value is greater than the provided value. Using greaterThan on non-numeric fields will raise an error.
  • greaterEquals: ensures that the fields value is greater than or equals the provided value. Using greaterEquals on non-numeric fields will raise an error.
  • after: ensures that the fields value is after the provided value. Using after on non-time fields will raise an error.
  • since: ensures that the fields value is after or at the provided value. Using since on non-time fields will raise an error.
  • before: ensures that the fields value is before the provided value. Using before on non-time fields will raise an error.
  • until: ensures that the fields value is before or at the provided value. Using before on non-time fields will raise an error.

query {
  entity(id: "123") {
      records {
          price
      }
      recordInsights {
          average(field: "price")
          max(field: "price")
          median(field: "price")
          min(field: "price")
          standardDeviation(field: "price")
          sum(field: "price")
      }
  }
}

{
  "data": {
    "entity": {
      "records": [
        {"price": 10},
        {"price": 20},
        {"price": 30},
        {"price": 15},
        {"price": 25},
        {"price": null}
      ],
      "recordInsights": {
        "average": 20,
        "max": 30,
        "median": 20,
        "min": 10,
        "standardDeviation": 7.0710678118655,
        "sum": 100
      }
    }
  }
}

This query retrieves all the price field for all the records of the entity, as well as some statistics related to the price field of their records. Specifically, it calculates the average, maximum, median, minimum, and sum of the prices, as well as their standard deviation.

query {
  entity(id: "123") {
      recordInsights {
          filter(conditions: [
              { field: "status", equal: "active" },
              { field: "created_at", after: "2022-01-01T00:00:00Z" }
          ]) {
              sort(criteria: [
                  { field: "created_at", direction: DESC },
                  { field: "priority" }
              ]) {
                  limit(count: 10) {
                      records {
                          id
                          name
                          status
                          priority
                          created_at
                      }
                  }
              }
          }
      }
  }
}

This query retrieves the RecordInsights for an entity with ID 123. It applies a filter to only include records where the status field is "active" and the created_at field is greater than or equal to January 1st, 2022. It then sorts the resulting records by created_at in descending order and priority in ascending order. It limits the result to 10 records starting from the first one. Finally, it selects the id, name, status, priority, and created_at fields for each of the selected records.

query {
  entity(id: "123") {
    recordInsights {
      group(fields: ["category"]) {
        records {
          id
          name
          category
        }
        count
        names: valuesDistinct(field: "name")
        categories: valuesDistinct(field: "category")
      }
    }
  }
}

Assuming the following records for the entity with ID "123":

[
  {
    "id": "1",
    "name": "Product A",
    "category": "Electronics"
  },
  {
    "id": "2",
    "name": "Product B",
    "category": "Electronics"
  },
  {
    "id": "3",
    "name": "Product C",
    "category": "Clothing"
  }
]

The response would be:

{
  "data": {
    "entity": {
      "recordInsights": {
        "group": [
          {
            "records": [
              {
                "id": "1",
                "name": "Product A",
                "category": "Electronics"
              },
              {
                "id": "2",
                "name": "Product B",
                "category": "Electronics"
              }
            ],
            "count": 2,
            "names": ["Product A","Product B","Product C"],
            "categories": ["Electronics","Clothing"]
          },
          {
            "records": [
              {
                "id": "3",
                "name": "Product C",
                "category": "Clothing"
              }
            ],
            "count": 1
          }
        ]
      }
    }
  }
}

This query groups the records by their category field, returning two groups: one for the "Electronics" category with a count of 2, and one for the "Clothing" category with a count of 1. The records field of each group contains the records in that group, and the count field is the total number of records in that group.

Provides statistics and aggregation on the entities edges and duplicates. This is available on the entity type.

• count: Int!: Returns the amount of edges in the provided list.
• frequencyDistribution(top: Int, direction: SortDirection): [FrequencyDistributionEntry!]!: Returns how often a rule is present.
• matrix(links: [String!]): [EdgeMatrixEntry!]!: Returns a matrix in which it is possible to see the links between each two records and due to which rule or duplicate they are linked.

query {
  entity(id: "123") {
    edges
    duplicates
    edgeInsights {
      matrix(links: ["R1", "R2", "R3", "duplicate"]) {
        a
        b
        links
      }
    }
  }
}

The response would be:

    "entity": {
      "edges": [
        "1:2:R1",
        "1:2:R2",

            "b": "4",
            "links": {
              "R1": false,
              "R2": false,
              "R3": false,
              "duplicate": true
            }
          }
        ]
      }
    }
  }
}

As you can see, the output of the edge matrix contains the same information as edges and duplicates. However, depending on the use case, it might be easier to work with on the client side. Also note, that the links parameter is optional. When omitting it, the result would not contain the values for R3 as they are all false, but would instead receive the output for R4, which was filtered out before.

During search, entity by ID and entity by record ID queries, you can provide optional filter criteria using the considerRecords field. This filters the entities that were originally found and only takes into account the records that match those filters. As a result all other properties (edges, duplicates and hits) are updated accordingly, as if the other records did not exist at all.

This may even lead to situations where you end up with multiple entities or no results at all, or even a much smaller entity, despite only filtering a single record. The result behaves exactly as if you would have never added those records or as you would remove them.

It can be used with a variety of what-if scenarios. For example, you can observe the state of an entity at any given time in the past using the until or before filter condition. Alternatively, you could use it to see what will happen when records are deleted due to old age using the after or since condition. Another use case is to visualize how an entity would appear without the records from a specific source by using the equals and invert filters.

Example for a time based filter:

{
  search(input: {
    parameters: {
    	myCustomField: "some-value"
    }
    considerRecords: {
      field: "myTimestamp"
      before: "2023-05-12T13:23:00Z02:00"
    }
  }) {
    entities {
      id
      records {
        id
        myCustomField
      }
      edges
      duplicates
      hits
    }
  }
}

This will return the entity with only records that have the custom field myTimestamp at a value before 2023-05-12T13:23:00Z02:00. The result then depends on how the records are connected and which records were hit.

Example for a filter to exclude certain record IDs:

{
  search(input: {
    parameters: {
    	myCustomField: "some-value"
    }
    considerRecords: [
      {
        field: "id"
        before: "<record-id-a>"
        invert: true
      },
      {
        field: "id"
        before: "<record-id-b>"
        invert: true
      }
    ]
  }) {
    entities {
      id
      records {
        id
        myCustomField
      }
      edges
      duplicates
      hits
    }
  }
}

This will ignore the records <record-id-a> and <record-id-b> before rebuilding the entity. Keep in mind that you still might end up with a lot less entities, if e.g. one of those two records were the only record that connected two larger clusters.

Many more filter options are available. Please use the GraphQL introspection feature to see what is possible.
