update_cache_salt: Update the cache when the salt is changed for an existing...

In robertzk/cachemeifyoucan: Cache Me If You Can

Description

Updating the salts of an existing cached function can be tricky. This utility handles that by copying over the cached data into new shards, add indexes, and add new entires into the table_shard_map.

Usage

update_cache_salt(dbconn, prefix, old_salt, new_salt)

Arguments

dbconn	SQLConnection. A database connection.
prefix	character. The prefix for the cached_fcn
old_salt	list. The old salt object.
new_salt	list. A new salt object.

Details

Note: The old shards aren't removed from the database but they can be safely removed once cached functions using the old salts are fully depricated.
