Upgrade to v0.12 from earlier versions

Features of this release

v0.12 introduces distributed clickhouse setup.

After upgrading to v0.12

Querying distributed tables

The new distributed tables in clickhouse have been named by prefixing distributed_ to existing single shard table names. If you have used clickhouse queries in dashboard or alerts, you would need to update the queries with the new table names. Eg, signoz_index_v2 now corresponds to the table of a single shard. To query all the shards, query against distributed_signoz_index_v2.

The old table names will continue to work for single node installations as long as you work with a single shard. We recommend changing table names at the earliest to make future upgrade to distributed setup easier.

For detailed instructions to include additional shards, go to Distributed ClickHouse documentation page.
