Waltz Versions Save

Changes include:

• Waltz Client's partition ensure mounted call throws WaitForMountedTimeoutException if transaction couldn't be submitted to Waltz within 10s because the transaction's partition is not mounted

Changes include:

• Minor bugfix of ClusterCli.Verify that prevents connection between client and server to be restarted during cluster verify call

Changes include:

• Fix preventing no longer used WaltzServerHandler from removing connection information of currently used WaltzServerHandler in a timing error
• Storage partition health refers to overall partition health instead of only failed partition recovery error
• Cluster state verification includes check of server partition's health
• Fix to prevent deadlock if number of replicas is 0
• Support of running Waltz locally in Docker on M1 chips
• Unregister server partition metrics only after successful completion of partition closure
• Waltz release to MavenCentral automation

Changes include:

• Fix of broken Waltz 0.12.0 release (compiled by unsupported Java version)
• Small change in WaltzServerHandler logging to capture logs from relevant client ids.

Changes include: • Fix to populate correct “high-water-mark” metric in WaltzServer when the node is started/restarted. • Implementation of keep-alive messages between the NetworkClient and NetworkServer to keep the connection channel active. • Few changes to StorageCli in order accept multiple partitions (as comma separated) instead of one partition. • Extra logging to identify Mounting issues.

Changes includes:

• Fix to make StringBuilder usage in Cli's as non-static.

Changes include: ▪ Fix to “add-storage.sh” docker script to pass the correct hostname. ▪ Adding getters to PartitionLocalLock class. ▪ Re-formatting the output of the few Cli’s. ▪ Custom metricGroup to isolate the metrics emitted via the rpcClient’s and the streamClient’s Partition object. ▪ A new metric I.e is-partition-active for WaltzClient’s Partition. ▪ WaltzClient metric typo fix.

Changes include:

• Allowing batch update to add/remove preferred partitions via ServerCli.
• Enabling logger output for CLIs: ClusterCli.verify, ServerCli.list, StorageCli.list, ZookeeperCli.list.
• Resolving Waltz Client from waiting forever on lock.wait() during mounting (which happens if the highWaterMark for a partition on Waltz Client is higher than that on the Waltz Server).
• Exposing the WaltzClient metrics via JmxReporter.
• Support for deploying multiple Waltz clusters locally in docker.

• New feature to introduce append lock (https://github.com/wepay/waltz/pull/77) and other improvements
