PHOENIX-4799 Write cells using checkAndMutate to prevent conflicting â¦
â¦changes
@vincentpoon @karanmehta93 @ChinmaySKulkarni Can you please review?
With this patch, when we add a column we write a cell to SYSTEM.CHILD_LINK
with row key (tenantId, schemaName, physicalTableName, columnName) to prevent
conflicting concurrent modifications.
While dropping a table or creating a view we also write a cell to
SYSTEM.CHILD_LINK with row key (tenantId, schemaName, physicalTableName).
This is done in MetadataClient before we make an rpc to create view / drop
table / add column.
