3.1.2 - 20 August 2020

Changes

Core

• Fixed NPE when trying to update a vertex that has an rid bag
• Ensure that file writes are finished on close
• Parameter to setup value of minimal compressed record size for WAL was introduced
• Infinite loop in case of restore was fixed
• Index check was removed from database check
• fixed timer creation in remote context
• managed correctly storage frozen status from transactions and sync
• Incremental backup does not introduce GC overhead
• Fix console output on CREATE INDEX
• add validation for embedded collections when creating properties in the schema
• Fix csv export (http) to also use schema to infer columns
• Improve logging of errors related to exceeded packet size (remote binary)
• Tracking of labels without vertex classes was disabled
• re-introduced record not found instead illegal argument in case of cluster not there

SQL

• Improve management of TIMEOUT in SQL for aggregations and ORDER BY
• Fix regression on SQL range queries with indexes

Distributed

• add reentrant logic to distributed lock hazelcast implementation
• first definition of the new executor for distributed requests
• passed list of rids from first phase to the second phase to make sure to follow the same locking logic
• fixed distributed executor thread factory
• handled the case of rejectd execution in distributed executor
• changed the database drop to not wait for the distributed executor shutdown
• add unique index keys to tx phase 1
• add some buffering in the distributed executor queue
• add tracking of transactions pending in the distributed executor queue
• add unique keys for execution scheduling in distributed second phase
• add transaction id partition as locking key for schedule operation sequential
• add check for transaction already included in the database due to synch appening while the transaction is active
• add check for avoid to apply second phases if the state already contains the transactions
• changed first phase to return invalid sequential in case of already present transaction id
• add coordinator scheduler locking for distributed tx
• add reset to temporary id for created record in transaction, in case of retry for concurrent create
• add context registration for already present transaction to avoid trigger sync
• removed wait in execution of distributed tasks that was not needed and could cause deadlocks
