Disk performance is vital to
maintaining a healthy Zookeeper cluster. Solid state drives (SSD) are highly recommended as
Zookeeper must have low latency disk writes in order to perform optimally. Each
request to Zookeeper must be committed to to disk on each server in the quorum
before the result is available for read. A dedicated SSD of at least 64 GB in
size on each Zookeeper server is recommended for a production deployment. You
can use autopurge.purgeInterval
to automatically cleanup Zookeeper data and lower maintenance overhead.
