Using Python to Operate Coherence

Coherence is a Distributed cache and data management platform, which provides an easy-to-use Python API to operate database connection and data insertion, query, modification and deletion operations. The following is an example of using Python to operate a Coherence database: Firstly, ensure that the Coherence and Coherence PyInstaller dependency libraries are installed. You can install it using the following command: bash pip install coherence pip install coherence-pyinstaller Next, import the necessary Coherence modules and classes: python from coherence import Coherence from coherence.api import Cache Create a Coherence instance and connect to the database: python coherence = Coherence("your_coherence_config.xml") cache = coherence.ensure_cache("your_cache_name") The following operations can now be used to operate the database: 1. Insert data: python cache.put("key", "value") 2. Query data: python value = cache.get("key") 3. Modify data: python cache.put("key", "new_value") 4. Delete data: python cache.remove("key") The complete example code is as follows: python from coherence import Coherence from coherence.api import Cache #Create a Coherence instance and connect to the database coherence = Coherence("your_coherence_config.xml") cache = coherence.ensure_cache("your_cache_name") #Insert Data cache.put("key", "value") #Query data value = cache.get("key") Print (value) # Output: value #Modify data cache.put("key", "new_value") #Delete data cache.remove("key") Please ensure to replace the "you_coherence_config. xml" and "you_cachename" in the example with the actual configuration file and cache name.
