GIGASPACES JDBC DRIVER

Our user class has a collection groups that he belongs to. This approach scales very well once the space have multiple partitions avoiding the need to retrieve the actual space objects from the space to evaluate the query. This will make sure the database activity would not increase the rego log size within the space to store large amount of space events that will cause slow space performance space send its activities in async mode to the database via the mirror. This approach reduces network overhead and can vastly improve performance. The main downside with options is the need to build the business logic that will persist the data or create the Hibernate hbm files and make your classes to have relevant getters and setters both for POJO and Entry classes.

The Change API reduces a normal two step operation to a one step operation.

The template is a POJO of the desired entry type, and the attributes which are set on the template i. In this part of the tutorial we will demonstrate how to create a space and how you can interact with it.

SQL Client

Porting existing JDBC code to the space is certainly doable but would require some level of adaptation depending on the specifics of the case and the complexity of the SQL queries. In some cases when querying the space for objects only specific attributes of an objects are required and not the entire object delta read. The connection URL should include: GigaSpaces persistent space includes several options: Related questions split-brain recovery strategies Unreachable spaces ConfigurationException java.

All client interaction is performed through this proxy. This is the location where you can place your business logic that read the data from the database and load it into the space. There are several additional indexing options available. This page describes an older version of the product. This will make sure the database activity would not increase the rego log size within the space to store large amount of space events that will cause slow space performance space send its activities in async mode to the database via the mirror.

For your reference, the original is [available here http: This page describes an older version of the product.

Doc and Examples for the above options: These meta model settings cannot be changed without restarting the space or dropping the type, clearing all its instances and reintroducing it again. List of JDBC error codes and their descriptions: It is also possible to write multiple objects in one operation to the space batch mode.

For more information see Indexing. Our user class has a collection groups that he belongs to.

For Embedded loader modeis this class implemented with ExternalDataSource interfacedeployed by gs-ui to each GigaSpace instance? With large databasethis might take some time.

SQL Driver

We can query the space for all users that belong to a certain group:. Object CatalogNumber, JavaType class java. Loading data into the space can be done in the following modes: To create a document we use a Map for its properties. You may use as part of the JDBC select statement nested fields. The POJO needs to implement jdbv default constructor, setters and getters for every property you want to store in the Space.

If it already ggaspaces in space it will be updated. So far this feature has been very popular with many of our accounts. You should deploy the ExternalDataSource implementation to each space.
