For example, if you Query a global secondary index and exceed its provisioned read capacity, your request will be throttled. An appropriate doc comment should then be provided.
To add Selenium to your Ruby environment run the following command from a command-line. If you perform heavy write activity on the table, but a global secondary index on that table has insufficient write capacity, then the write activity on the table will be throttled.
The context object offers methods to store and retrieve data shared in the context. Non-reentrant readers are not allowed until all write locks held by the writing thread have been released.
For queues successful passive declares will return the same information as non-passive ones, namely the number of consumers and messages in ready state in the queue.
Each Channel has its own dispatch thread. WebDriver will find the form for us from the element element. Warning Multi-threaded worker verticles are an advanced feature and most applications will have no need for them.
However, upgrading from a read lock to the write lock is not possible. You are not using the Java bindings i. Annotation - Does not directly affect program semantics, but does affect the way programs are treated by tools and libraries, which can in turn affect the semantics of the running program.
One such file should go into each package directory of the source tree. In that context, when a verticle is deployed on a vert. Note that when creating an explicit constructor, it must match precisely the declaration of the automatically generated constructor; even if the constructor should logically be protected, it must be made public to match the declaration of the automatically generated constructor, for compatibility.
When calling the API methods relating to Consumers, individual subscriptions are always referred to by their consumer tags. To be notified of such returns, clients can implement the ReturnListener interface and call Channel.
First, create a folder to contain your Selenium project files. When all the operations succeed, the resulting future is completed with a success. Consider the following data returned from a Query that requests gaming data for a leaderboard application: Only the items with the specified key values appear in the response; within that set of data, the items are in no particular order.
More details about the high availability feature and configuration in the High Availability and Fail-Over section. From the standpoint of performance it is generally only worth mapping relatively large files into memory.
Additionally, a writer can acquire the read lock, but not vice-versa. For more information, see Filter Expressions for Scan. By default blocking code is executed on the Vert. Thus, if you queried GameScores for all the Comet Quest items, you would get the following four items: This is very important when you make your API public at a later stage.When Vert.x provides an event to a handler or calls the start or stop methods of a Verticle, the execution is associated with a mint-body.comy a context is an event-loop context and is tied to a specific event loop thread.
So executions for that context always occur on that exact same event loop thread. A channel for reading, writing, mapping, and manipulating a file. A file channel is a SeekableByteChannel that is connected to a file.
It has a current position within its file which can be both queried and mint-body.com file itself contains a variable-length sequence of bytes that can be read and written and whose current size can be queried. The size.
A NullPointerException in Java application is best way to solve it and that is also key to write robust programs which can work smoothly. As it said “prevention is better than cure”, same is true with nasty NullPointerException. I'm trying to write an automated test of an application that basically translates a custom message format into an XML message and sends it out the other end.
I've got a good set of input/output me. From Java to Go, and Back Again. 13 October Dominic Fox. Introduction: fitness landscapes, Cassandra, and making things worse In Lisp, you don't just write your program down toward the language, you also build the language up toward your program.
Returns a collection containing threads that may be waiting to acquire the write lock. Because the actual set of threads may change dynamically while constructing this result, the returned collection is only a best-effort estimate.Download
