GIGASPACES JDBC DRIVER DOWNLOAD

The node must have enough free memory while executing a non-collocated join to hold the entire build table in the memory of the single partition. Object Category Async persistency via option 3 or option 4 - aka Mirror Service The suggested way is to use option 5. Please sign in tags users badges help. See more in Logging section. Future versions will resolve this inconsistency.

The latest stable version is This my affect performance.

It is also the most efficient approach in terms of performance. Partitioning is used when the total number of objects is too big to be stored in a single space. This can vastly improve the performance if you need to load many objects at once into the space. If there are several classes with the same name but in different packages in the classpath, the full class name needs to be specified by replacing the package separator.

SQL Driver

This operation can vastly improve performance when you have an object with many attributes and you only need to update one or a couple of attributes. To improve performance, gugaspaces is possible to index one or more attributes for an object.

If it already exists in space it will be updated. Lazy load by implementing the DataProvider interface.

Interacting with the Space

Object Category Please start posting anonymously - your entry will be published after you log in jebc create a new account. When using a Nested Loop Jointhe linear search is applied against the build table for each item in the probe table. Attributes with null values are ignored not matched. Currently, simplicity is essential during our evaluation of GigaSpaces.

Each partition loads the build table from the entire cluster and stores it in memory.

I have N partitions of data that keeps unrelated partitions of my data. There are several additional query options available. Since the SQL support is limited, this path should be taken with caution. The SQL query support is provided in two flavors: The following examples assume the default constructor giyaspaces the User class initializes all its attributes to null.

Interacting with the Space

Only properties with special roles like ID and Routing are part of the schema definition. However, our SQL support is extremely useful for customers who want simple integration with extisting application and to execute complex queries on a Space gigaspcaes. Matching a nested attribute is done by specifying a Path which describes how to obtain its value.

All client interaction is performed through this proxy. With this parameter, all joins are executed on the client side. It uses the Cartesian product of the tables data to form the result set. In some cases when querying the space for objects only specific attributes of an objects are required and not the entire object delta read.

When writing an object to the space, the object is created in space if it does not exist. Each table is represented in the space by objects that hold its properties and gigaxpaces. This page describes an older version of the product. With the space, I deploy also some Services.

All the calculations are performed on the server side. Primary backup replication problem. Please sign in tags users badges help.
