FileCacheManager

class FileCacheManager(context: Context, filePath: String, perFileSizeThreshold: Int = 15000) : InMemoryCacheManager

File cache manager: Class that stores events to the file system in disk

Purpose of the class: Keep synced with memory

eventToFileIdMap - Each event with unique event id is mapped to file id (unique name of the file)

uniqueFileId - Unique Id of the file (or name of the file) in which events are pushed

All the file operations are running in the background thread

Any operation failure invoke moveInMemoryDataToFile as a fallback which cleans all the disk and re sync
