is bookkeeper stream storage, pulsar standalone and zookeeper

[nareshv]

Pulsar standalone has flags like --no-stream-storage. Is it ok to skip using stream storage for production use ?

Also, does disabling stream storage avoid bookkeeper from using zookeeper ?

Pulsar standalone has flags like --no-stream-storage. Is it ok to skip using stream storage for production use ?

Yes, it's not needed for Pulsar's core functionality. Stream storage is used for stateful functions.
In general, Pulsar standalone isn't designed for "production use", but everyone can decide on their own what they use it for.

Also, does disabling stream storage avoid bookkeeper from using zookeeper ?

No, stream storage requires using Bookkeeper. The parameter --no-stream-storage is unrelated to configuring the metadata store type and whether Zookeeper is used. Pulsar standalone will not use zookeeper by default.
To use Zookeeper in Pulsar standalone, PULSAR_STANDALONE_USE_ZOOKEEPER=1 environment variable should be set.
There has been some instability in using the default Rocksdb based metadata store in Pulsar standalone and that's why the docs now recommend using Zookeeper based storage. That document change was made recently with PR apache/pulsar-site#871 due to issues described in #20985 .
For actual production deployments, StreamNative Oxia is becoming a stable alternative for Zookeeper.

Pulsar standalone seem to be a bit closer to realizing https://github.com/apache/pulsar/wiki/PIP-21:-Pulsar-Edge-Component

We are using something like /bin/env PULSAR_STANDALONE_USE_ZOOKEEPER=1 $PULSAR_DIR/bin/pulsar-daemon start standalone --no-functions-worker and wondering if we can disable the stream storage. Looks like we can disable it if we don't use stateful functions
