ATTACHMENT ID: 12828885 - PreCommit-HIVE-MASTER-Build
> document threading model of Streaming API
> -----------------------------------------
>
> Key: HIVE-14778
> URL: https://issues.apache.org/jira/browse/HIVE-14778
> Project: Hive
> Issue Type: Bug
> Components: HCatalog, Transactions
> Affects Versions: 0.14.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Attachments: HIVE-14778.patch
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The model is not obvious and needs to be documented properly.
> A StreamingConnection internally maintains 2 MetaStoreClient objects (each
> has 1 Thrift client for actual RPC). Let's call them "primary" and
> "heartbeat". Each TransactionBatch created from a given StreamingConnection,
> gets a reference to both of these MetaStoreClients.
> So the model is that there is at most 1 outstanding (not closed)
> TransactionBatch for any given StreamingConnection and for any given
> TransactionBatch there can be at most 2 threads accessing it concurrently. 1
> thread calling TransactionBatch.heartbeat() (and nothing else) and the other
> calling all other methods.
