Extracting data from heterogeneous sources with library conflicts

One or more non-transitory computer-readable media comprising instructions which, when executed by one or more hardware processors, cause performance of operations comprising:

• instantiating a loader type to create a first descendant loader that is a first descendant of an ancestor loader;
• instantiating the loader type to create a second descendant loader that is a second descendant of the ancestor loader;
• loading, by the first descendant loader into an execution environment, a first plugin and a first set of one or more libraries needed to complete a first operation;
• loading, by the second descendant loader into the execution environment, a second plugin and a second set of one or more libraries needed to complete a second operation;
• wherein a first type comprised within the first set of one or more libraries and a second type comprised within the second set of one or more libraries (a) cannot be loaded by a same loader into the execution environment and (b) can be loaded into the execution environment using different loaders;
• invoking a first method of the first plugin, the first method comprising instructions for completing the first operation;
• and
• invoking a second method of the second plugin, the second method comprising instructions for completing the second operation.

A system comprising:

• at least one device comprising one or more hardware processors;
• the system being configured to perform operations comprising:
• instantiating a loader type to create a first descendant loader that is a first descendant of an ancestor loader;
• instantiating the loader type to create a second descendant loader that is a second descendant of the ancestor loader;
• loading, by the first descendant loader into an execution environment, a first plugin and a first set of one or more libraries needed to complete a first operation;
• loading, by the second descendant loader into the execution environment, a second plugin and a second set of one or more libraries needed to complete a second operation;
• wherein a first type comprised within the first set of one or more libraries and a second type comprised within the second set of one or more libraries (a) cannot be loaded by a same loader into the execution environment and (b) can be loaded into the execution environment using different loaders;
• invoking a first method of the first plugin, the first method comprising instructions for completing the first operation;
• and
• invoking a second method of the second plugin, the second method comprising instructions for completing the second operation.
