…dieFlinkWriteClient (#7509)
Different with other write clients, HoodieFlinkWriteClient invokes the
dataset writing methods(#upsert or #insert) for each batch of new data set in
the long running task. In current impl, a engine-specific hoodie table would be
created before performing these actions, and before the table creation, some
table bootstrapping operations are performed(such as table upgrade/downgrade,
the metadata table bootstrap). These bootstrapping operations are guarded by a
trasanction lock.
In Flink, these bootstrapping operations can be avoided because they are all
performed only once on the coordinator.
The changes:
- Make BaseHoodieWriteClient#doInitTable non abstract, it now only performs
the bootstrapping operations
- Add a default impl BaseHoodieWriteClient#initMetadataTable for metadata
table bootstrap specifically
- Add a new abstract method for creating engine-specific hoodie table
(cherry picked from commit fd62a1413e74de686935672aec812aacd5c43a63)
