Hi Tim,
Using the store module, is it possible to read and merge multiple custom stores into main memory
We could add an argument (or options) to file:read to allow entries to be added to an existing main-memory store.
set a particular store as context for a query?
The recommended approach is to invoke store:read before any other operation in the query. Please note, however, that the store will be globally available. If a second query runs on the same server and opens another store, it will change the behavior of the first query. For such use cases, it’s better to use databases.
Or, do I need to serialize the stores, e.g., as JSON and then create databases for them?
You could have a look at the new db:get-value and db:put-value functions [1]: These functions have particularly been designed to organize XQuery items in databases, making casts to JSON or XML obsolete.
Hope this helps, Christian
