byteayan opened a new pull request, #535:
URL: https://github.com/apache/hugegraph-doc/pull/535
## Purpose of the PR
- link apache/hugegraph#3254
- paired with apache/hugegraph#3355; merge after it
apache/hugegraph#3355 changes the Store's shipped
`rocksdb.total_memory_size` to `0`. With `0` or no value, the Store sizes the
RocksDB budget as half of what is left after the JVM max heap,
`MaxDirectMemorySize` and a 1.5 GiB reserve, clamped to 256 MiB to 32 GB. An
unset `MaxDirectMemorySize` counts as the heap size, at most 1 GiB. Inside a
container it starts from the cgroup memory limit, including a limit on a parent
cgroup the Store can see. The Docker entrypoint also gains
`HG_STORE_ROCKSDB_TOTAL_MEMORY_SIZE`. The site still documented the old
`32000000000` value and said that `0` meant the JVM max heap.
Changes, in English and Chinese:
- `quickstart/hugegraph/hugegraph-hstore.md`:
- Rewrote the `rocksdb.total_memory_size` row: the new distribution value
`0`, the auto-sizing rule, the off-heap caches plus the separate 1 GiB Raft log
cache, the 1 MiB minimum for an explicit value, and plain bytes only.
- Added an upgrade note to that row: an `application-pd.yml` kept from an
earlier release still says `32000000000` and has to be set to `0` to auto-size.
- Added "at least 1" to the GB rounding in the `raft.disruptorBufferSize`
row, which the code fix now guarantees.
- Added the new variable to the master Docker env table.
- `guides/hugegraph-docker-cluster.md`: added the variable to the Store
table, with one line pointing to the configuration reference.
`bash dist/validate-links.sh` passes and `git diff --check` is clean. I did
not build the site locally because Hugo is not installed on this machine.
