#Quick node how to
To learn how to secure your connection with proper certificates, see the Node.js TLS connection tutorial. While this is super helpful in streamlining the connection process for development purposes, it's not very secure and should not be used in production. NOTE on TLS: The connection logic in this sample app ignores mismatched certificates with the parameter tls_verify=none.
This flag determines if the connection should use TLS or not, as TLS is required for Capella. IS_CAPELLA - true if you are using Capella, false otherwise.CB_PASS - The password that corresponds to the user specified above.Follow these instructions to create database credentials on Capella CB_USER - The username of an authorized user on your cluster.Use localhost for a local/Docker cluster, or the Wide Area Network address for a Capella instance (formatted like cb.) CB_URL - The Couchbase endpoint to connect to.
#Quick node update
We've included a dev.env file with some basic default values, but you may need to update these according to your configuration. The node property in the GDS graph to which the embedding is written.Git clone Configure environment variables appropriately Milliseconds for preprocessing the graph.Ĭonfiguration used for running the algorithm.Ĭonfiguration: Map Table 7. It is required that iterationWeights is non-empty or nodeSelfInfluence is non-zero.Ĭonfiguration: Map Table 4. The number of iterations is equal to the length of iterationWeights. If unspecified, the algorithm runs unweighted. Name of the relationship property to use for weighted random projection. The initial random vector for each node is scaled by its degree to the power of normalizationStrength.Ī random seed which is used for all randomness in computing the embeddings. The weight controls how much the intermediate embedding from the iteration contributes to the final embedding.Ĭontrols for each node how much its initial random vector contributes to its final embedding. Minimum value is 1.Ĭontains a weight for each iteration. The dimension of the computed node embeddings. All property names must exist in the projected graph and be of type Float or List of Float. The names of the node properties that should be used as input features. A positive value requires featureProperties to be non-empty.
