v1.4.2

• stfsender: fix deadlock when FLP-standalone memory pressure test is active
• tfscheduler: publish TF rates of ITS threshold scans
• tfbuilder: parallelize stf request grpc calls
• tfbuilder: add blocking mode for rdma (optional, saves 0.5 CPU core)
• data-model: make new hdr scheme default (O2-2814)

v1.4.1

• tfscheduler: add run nunber to infologger
• monitor: prevent rate logging without run number
• tfscheduler: log fix TfBuilder UCX Disconnection error: gRPC error when connecting StfSender
• monitoring: prevent numeric max and mins
• tfscheduler: do not count dropped late stfs into the dropped TFs
• tfbuilder: optimize RDMA loop: move key to pre, and monitoring to post

v1.4.0

• Improve STF meta notification by using ucx active messages
• Optimize RMA worker/endpoint utilization. TfBuilder needs only a small number of workers to optimally perform rma-get.
• Improvements in connection monitoring and reporting
• TfScheduler: fix typo causing delayed incomplete TF building (bugfix)

v1.3.13

• grpc: init grpc early to allow loading of control plugins with grpc
• ucx: transport performance optimization of RDMA-read scheduling

v1.3.12

• tfscheduler: fix under-reporting of incomplete tfs
• tfscheduler: report global accept/rejects rates and sizes
• tfscheduler: improve scheduling of incomplete tfs on completion and timeout
• tfbuilder: handle the case when all stfs are not available any longer or grpc requests failed
• consul: decrease connection timeout for retries to 5 seconds

v1.3.11

• grpc: speed up connection establishing
• tfscheduler: stop propagating tfs with no detector data to epn
• tfscheduler: monitor rpc duration (optional)
• stfsender: remove unclaimed stfs after a timeout (EPN-49)
• tfbuilder: prevent activating TfBuilder if grpc::StfDataRequest() cannot be made in InitTask() (EPN-49)

v1.3.10

• fix for compilation with CS8 GCC (FLP)

v1.3.9

DataDistribution v1.3.9:

• FIX: tfbuilder rpc: revert deadline for grpc:StfDataRequest()
• tfbuilder: add stf selection method options (consul): random (default), linear, stfsize.
• monitoring: add option to monitor grpc call duration (disabled by default)
• tfscheduler: use thread pool for async drop of stfs
• tfbuilder: monitor total time for all grpc StfDataRequest calls per TF
• tfbuilder: optimize stf in flight accounting
• tfbuilder: decrease min number of ucx threads to 4

v1.3.8

• fix rate monitoring underflow
• publish fmq device state as a metric to help diagnose delayed start

v1.3.7

stfsender: decrease amount of used data buffers in standalone runs to 128MB
stfbuilder: do not require partition id in standalone runs (FST)
improve logging messages (sending End of Stream)
consul: implement connection retries (EPN-29)
