There > is no IO overhead when we lookup the cached table. Reload dimension table > periodically for update, and we can reload asynchronously with little IO > delay. > The cache needs to be reloaded periodically for update。 > Limitations: > 1. It's suitable for scenario that users don't care the lateness so much, > periodically updating can satisfy them. > 2. The “ALL” cache needs more memory, so it's suitable for small dimension > table. -- This message was sent by Atlassian Jira (v8.3.4#803005)
