TenantCache: a cache to store tenant information and API token information and semi-permanent data to avoid unnecessary roundtrips. ? These API tokens are then stored in a local cache (the TenantCache using Redis), alongside with other rather static information of the environments: ? tenant-token the current API token to use.

Streams provide you with the underlying infrastructure to create new applications, such as continuously updated free-text search indexes, caches, or other creative extensions requiring up-to-date table changes. An AWS Lambda function is a simpler option that you can use, as it only requires you to code the logic, set it, and forget it.

What users see in their browser window and the underlying HTML code are both governed by the DOM, which creates a tree-like structure for all HTML elements. Combined with in-depth capture of all events that take place, teams can spot common user pain points.

The Tech Hollow , an OSS technology we released a few years ago, has been best described as a total high-density near cache : Total : The entire dataset is cached on each node?—?there there is no eviction policy, and there are no cache misses. Near : the cache exists in RAM on any instance which requires access to the dataset.

Logs are important because you’ll naturally want an event-based record of any notable anomalies across the system. Timestamps, values, and even event names can preemptively uncover a growing problem that needs remediation. This occurs once data is safely stored within a local cache.

Adding forking logic and complexity to the device code can create dependencies on device application release cycles that generally run at a slower cadence than service release cycles, leading to bottlenecks in the migration. There is also an increased risk that bugs in the replay logic have the potential to impact production code and metrics.
