     *                           “eventually-consistent”, i.e. eventually all the data in ArangoDB will be matched by corresponding query
     *                           expressions. The concept of ArangoSearch view “commit” operation is introduced to control the upper-bound on the
     *                           time until document addition/removals are actually reflected by corresponding query expressions. Once a “commit”
     *                           operation is complete all documents added/removed prior to the start of the “commit” operation will be reflected
     *                           by queries invoked in subsequent ArangoDB transactions, in-progress ArangoDB transactions will still continue to
