XAP

Work Directory

After deploying the application, a work directory is automatically created. You can find this directory at gs-home/work. Inside, you'll see folders that manage different system operations, including:

Folder Usage Link to Additional Information
replication

Used for byte buffer redo log.

This is system data and cannot be deleted while the application is running.

This data cannot be updated manually.

Controlling the Replication Redo Log
redolog

Used for SQLite based redo log.

This is system data and cannot be deleted while the application is running.

You can use the data if you are manually recovering data. (redo log page in). Automatically it will not be used in a restart of the system and will be deleted.

This data cannot be updated manually.

gsa

XAPClosed GigaSpaces eXtreme Application Platform. Provides a powerful solution for data processing, launching, and running digital services Only.

Where the PID of the GSAClosed Grid Service Agent. This is a process manager that can spawn and manage Service Grid processes (Operating System level processes) such as The Grid Service Manager, The Grid Service Container, and The Lookup Service. Typically, the GSA is started with the hosting machine's startup. Using the agent, you can bootstrap the entire cluster very easily, and start and stop additional GSCs, GSMs and lookup services at will. is saved, plus related files for process control.

This cannot be deleted while the application is running.

manager

ZookeeperClosed Apache Zookeeper. An open-source server for highly reliable distributed coordination of cloud applications. It provides a centralized service for providing configuration information, naming, synchronization and group services over large clusters in distributed systems. The goal is to make these systems easier to manage with improved, more reliable propagation of changes. Database

memoryxtend

MemoryXtendClosed Related to Data Tiering. The MemoryXtend (blobstore) storage model allows an external storage medium (one that does not reside on the JVM heap) to store the GigaSpaces Space data and is designed for operational workloads. It keeps all indexes in RAM for better performance. RocksDB data files (if being used).

This is system data and cannot be deleted while the application is running. Additionally, if this data is being used as the persistence layer and you plan to load a new system with it, deletion is not recommended to ensure data reuse.

This data cannot be updated manually.

MemoryXtend Overview
processing-units

A Snapshot of Processing UnitsClosed This is the unit of packaging and deployment in the GigaSpaces Data Grid, and is essentially the main GigaSpaces service. The Processing Unit (PU) itself is typically deployed onto the Service Grid. When a Processing Unit is deployed, a Processing Unit instance is the actual runtime entity. deployed to a SpaceClosed Where GigaSpaces data is stored. It is the logical cache that holds data objects in memory and might also hold them in layered in tiering. Data is hosted from multiple SoRs, consolidated as a unified data model..

Each entry is timestamped, so it is possible to delete old files that have not been used during the last install of the system.

This data cannot be updated manually.

 
rest-jetty

A temp directory where the RESTClosed REpresentational State Transfer. Application Programming Interface An API, or application programming interface, is a set of rules that define how applications or devices can connect to and communicate with each other. A REST API is an API that conforms to the design principles of the REST, or representational state transfer architectural style. manager is extracted to.

It is permissible to delete the contents of this folder if the files have not been deleted which could happen when managers are restarted too often.

RESTresources

These are resources using in PUs

This cannot be deleted while the application is running.

This data cannot be updated manually.

 
tiered-storage

SQLite DB for tiered storageClosed Automatically assigns data to different categories of storage types based on considerations of cost, performance, availability, and recovery. (if it is being used).

This is system data and cannot be deleted while the application is running. Additionally, if this data is being used as the persistence layer and you plan to load a new system with it, deletion is not recommended to ensure data reuse.

This data cannot be updated manually.
