Kirill Gusakov updated IGNITE-19505:
------------------------------------
Description:
*Motivation*
Current data layout is builded around the table partitions. Each table
partition forms the group of replicas with the RAFT protocol (pluggable
protocol in future). This layout was great up to the moment, when we decided to
introduce the support of collocation for any chosen group of tables.
After some rounds of discussions we decided to use the distribution zone as the
scope of collocation. So, the partition will be managed by the distribution
zone entity, instead of the table one.
*Definition of done*
Under this issue we need to provide the design document, which will describe
the process for migration the current state to the:
- Table partitions must be the part (one-to-one relation) of the zone partition.
- The data layout for partitions of different tables inside the one zone
partition - must be described as well.
- Tables, which share the one distribution zone will be collocated (the same
key must be stored in the same distribution zone partition)
