![]() Strong and very long password so that this attack is infeasible. TIP: because of the high performance nature of KeyDB, it is possible to tryĪ lot of passwords in parallel in very short time, so make sure to generate a ![]() Otherwise, an error is returned and the clients needs to try a new password. With the OK status code and starts accepting commands. If password matches the password in the configuration file, the server replies This is done using the requirepass directive in the configuration file. KeyDB can be instructed to require a password before allowing clients to execute Request for authentication in a password-protected KeyDB server.

Of operation, there is no way to cut the time series to a given size easilyīecause KeyDB currently lacks a command able to trim string objects. The limitation of this pattern is that we are forced into an append-only mode SETRANGE can be used to overwrite an existing time series.If our time series have associated time information we can easily implementĪ binary search to get range combining GETRANGE with the Lua scripting GETRANGE allows for random access of elements.STRLEN can be used in order to obtain the number of samples.Upper Saddle River, N.J.: Prentice Hall.APPEND timeseries "fixed-size sample" CopyĪccessing individual elements in the time series is not hard: ``Faster Evaluation of Shortest-Path Based Centrality Indices.'' Konstanzer Schriften in Mathematik und Informatik, 120. Because the valued-case algorithm is significantly slower than the unvalued-case algorithm, ignore.eval should be set to TRUE wherever possible. Setting ignore.eval=FALSE will change this behavior, with edge values being interpreted as distances where edge values reflect proximity or tie strength, transformation may be necessary. geodist (without loss of generality) treats all paths as directed, a fact which should be kept in mind when interpreting geodist output.īy default, geodist ignores edge values (except for NAed edges, which are dropped when na.omit=TRUE). ![]() Note that the choice of infinite path length for disconnected vertex pairs is non-canonical (albeit common), and some may prefer to simply treat these as missing values. This routine is used by a variety of other functions many of these will allow the user to provide manually precomputed geodist output so as to prevent expensive recomputation.
