Native Client for VMware Tanzu GemFire 10.2 Documentation
Published January 19, 2021.
The Native Client for VMware Tanzu GemFire is a library that provides access for C++ and Microsoft® .NET™ clients to a GemFire distributed system.
The Release Notes, below, describe a new feature and list issue resolutions for both C++ and .NET clients.
The C++ and .NET clients are documented in separate user guides:
See the API docs for API details:
See the VMware Tanzu GemFire User Guide for information regarding the server.
Native Client for VMware Tanzu GemFire version 10.2 is based on Apache Geode Native.
The Apache Geode community has a host of examples based on the latest C++ and .NET APIs (https://github.com/apache/geode-native/tree/develop/examples).
Native Client for VMware Tanzu GemFire version 10.2 includes the following enhancements:
- Support for off-platform access to VMware Tanzu GemFire for VMs via SNI proxy
- Support for autoserializing unsigned types, guids, and decimals
- Support for lazy loading of OpenSSL, significantly improving the developer’s experience on Windows when using .NET
- Performance improvements for PDX deserialization
- Addition of a client-side exception for server low memory
GemFire 10.2.1 is a maintenance release that resolves a variety of issues—see Issues Resolved in Native Client 10.2.1 for more information.
GEMNC-492: .NET session state provider now correctly parses a
locators parameter in
Web.config that specifies multiple locators.
GEMNC-494, GEODE-8806: Fixed log rolling code to properly honor file and disk space limits.
GEODE-7868: Added support for autoserializing unsigned types, guids, and decimals.
GEODE-7930: Endpoint names are no longer truncated to 99 characters. The Native Client now supports endpoint names that meet the RFC 2181 standard of 255 characters for fully-qualified domain names. This solution also corrects a spurious “Failed to add endpoint” error that was issued when, in fact, no error had occurred.
GEODE-7944: Fixed a “No locators available” exception that occurred when subscriptions are enabled and
GEODE-8015, GEMNC-470: Added debugging symbols to the released libraries. The Native Client release for Windows now includes a .pdb symbol file. On Linux, the symbols are now embedded in the shared library (.so file).
GEODE-8053: Fixed a shutdown hang. The statistics-gathering system’s StatsManager no longer attempts to run on a closed, but not yet destroyed, Cache instance.
GEODE-8102: Added support for lazy loading of OpenSSL, significantly improving the developer’s experience on Windows when using .NET.
GEODE-8181: Changed default setting for
false to match behavior of the Java client.
GEODE-8212: Reduced the number of server connections required to obtain a type ID, improving the performance of PDX deserialization.
GEODE-8537: Fixed a memory leak that occurred when LRU eviction was enabled.
GEODE-8614: Added a client-side exception for server low memory.
GEODE-8397, GEODE-8398: Extended PoolFactory API to support SNI proxy and added SNI support to .NET API.
GEODE-8441, GEMNC-468: Fixed an issue where AppDomainContext was initialized too late, generating the exception “Can’t pass GCHandle across AppDomains”.
GEODE-8674, GEMNC-488: Fixed a memory leak that occurred when a DataInput object created using a constructor with a buffer parameter is removed.
GEODE-8754, GEMNC-485: Fixed a deserialization error in .NET DataInput::ReadObject.
GEODE-8773, GEMNC-490: Fixed bug which caused client PING and CLOSE_CONNECTION calls to implicitly initiate a transaction on servers.
