Performance Improvements
Overview
During the past year, Signiant formed a cross-functional dedicated team to actively monitor, identify, and resolve critical performance-impacting scenarios with Reach Engine. As a result, over 80% of unneeded database space was removed, and used valuable insight, and visibility, to stable operations for key clients.
The observations made by the team led to a joint effort between the support, solutions, and engineering teams, resulting in a scalable and stable system that will support the growth of the Reach Engine clients in the coming years.
A review of the entire Reach Engine system as a whole led to an engineering focus on three integrated areas for improvement and re-design.
Database and Exec Server Improvements
We’ve improved system-wide work assignment by targeting communication between the system services for Reach Engine backend operations.
- Improved CPU cycles on workflow runtimes by optimizing expensive threads reducing overall processing weight allowing for downstream operations to utilize released CPU resources
- Added a new back pressure function to exec servers during runtime saturation resulting in improved high-volume execution during workflow activities
- Introduced new Thread Pool Tuning thresholds designed to balance exec server polling which has improved request time by more than 40%
- Developed an optional database partitioning strategy that would further improve read-write times supporting workflow speed
| Internal Tracking ID | Title | Version |
| 94818 | NEW Support for ECS Object Storage S3 with Endpoint URL | 2.17.1 |

| 97005 | Runtime node work-order management | 2.17.3 |
| 93901 | Add NEW back pressure mechanism | 2.17.3 |
Improved Data Handling at Scale
Data layer handling in all areas including error handling and exceptions has been improved by up to 400% by making significant changes to RQL handling based on Reach Engine client's use of query language and its fundamental role in future platform operations.
- Data GET operations now respond with standardized JSON data sets for tighter paging of data supporting larger overall data handling from exec servers to database.
- Data object responses now operate on reduced data response sets, enabling critical business workflows to operate with greater efficiency by improving metadata batch updates by over 50%.
- Improved error handling in the data layer allows for improved request response times and leads to improved workflow step transitions.

Workflow Step and Execution Improvements
Workflow handling has been completely revamped to ensure more scalable and stable operations.
- Moved to synchronous write handling and queuing to ensure more predictability when multiple runtimes are engaged.
- Introduced detection for synchronous metadata submits and implemented controls for management allowing the engine to be more predictive and reducing the need for unneeded and process heavy in flight polling.
- Reduced the overall need for sub-flow execution due to sub-flow fail and retry.
- Workflow step queuing has been redesigned for foundational steps resulting in a 4x test performance improvement:
- Improved deep controls for query, HTTP submit, and poll intervals.
- Improved error checking and resolution controls resulting in the elimination of long polling and locked polling conditions.
- New max retries and elimination of expression runs.
