Hi all, Here’s the update on IoTDB development progress at Timecho this week:
- Data Subscription Optimization: (1) Fixed an issue where subscriptions in snapshot mode could be dropped prematurely. (2) Fixed a bug in the export-tsfile.sh script: when exporting full data with a limited time range across partitions, data from incomplete partitions could be lost. - Data Sync Optimization: (1) Fixed potential NPE when using sink format=tsfile and the tablet contains null values. (2) Added TsBlock support to Session-CPP. (3) Fixed sync stalls caused by disk full errors on the receiver side. (4) Improved upgrade/downgrade strategy for synchronization. (5) Improved memory control in Pipe. (6) Reduced the number of file retransmissions. (7) Optimized Pipe/Load configuration parameters. (8) Improved retransmission targeting in IoTV2. (9) Enhanced performance of Drop/Alter Pipe in certain scenarios. - Feature Development: (1) Table mode prediction functionality completed. (2) MATCH_RECOGNIZE functionality completed. (3) Correlated subquery functionality completed. (4) Window function support completed. (5) approx_most_frequent function implementation completed. Looking forward to your feedback! Have a nice weekend :) Best regards, Pengcheng The Timecho Team
