------------------------------------------
Summary: Basic volatile RAFT log storage
Key: IGNITE-17334
URL: https://issues.apache.org/jira/browse/IGNITE-17334
Project: Ignite
Issue Type: Improvement
Components: persistence
Reporter: Roman Puchkovskiy
Assignee: Roman Puchkovskiy
Fix For: 3.0.0-alpha6
The storage should contain the following components:
# An elastic (but with possible hard-limit) in-memory storage for log entries.
On this iteration it will be on-heap data structure (for instance, a skip
list). Later, we'll build something better (like an off-heap implementation,
maybe using pagemem).
# An algorithm for determining when the in-memory storage cannot accept new
entries. On this iteration, the only supported algorithm will be simply
limiting the store by the number of stored entries. Later we will add something
smarter, like the total size of the stored entries and adaptive algorithms.
# A policy for what to do if the store cannot accept a record. On this
iteration, it will be just to reject the entry. Later, we can add support for
spilling out to disk.
