A very simple thread-safe progress bar that should work on every OS without problems. I needed a progress bar for croc and everything I tried had problems, so I made another one. In order to be OS agnostic I do not plan to support multi-line outputs. The progressbar implements an io.Writer, so it can automatically detect the number of bytes written to a stream, so you can use it as a progress bar for an io.

...Interface-based dynamic and flexible configuration of different data tables and target libraries. Multiple data sources, multiple target library support. Both incremental and full data synchronization are supported. One Binlog parsing thread, multiple target libraries are synchronized in parallel. Automatically restore configuration after restarting after downtime, accurate control of location. Support monitoring and alarm functions such as Email and WeChat enterprise account. Provide third-party monitoring platform access interface (Http Basic authentication) HTTP API. ...

...Connections support one concurrent caller to the Receive method and one concurrent caller to the Send and Flush methods. No other concurrency is supported including concurrent calls to the Do and Close methods. For full concurrent access to Redis, use the thread-safe Pool to get, use and release a connection from within a goroutine.

...We then tried using a sharded map, with shard eviction to release memory, which caused us memory issues. We then repurposed Groupcache’s LRU, using mutex locks for thread safety. After having it around for a year, we noticed that the cache suffered from severe contention. A commit to remove that cache caused our query latency to dramatically improve by 5-10x. In essence, our cache was slowing us down! We concluded that the concurrent cache story in Go is broken and must be fixed. In March, we wrote about the State of Caching in Go, mentioning the problem of databases and systems requiring a smart memory-bound cache which can scale to the multi-threaded environment Go programs find themselves in.

...The Actor Model provides a higher level of abstraction for writing concurrent and distributed systems. It alleviates the developer from having to deal with explicit locking and thread management, making it easier to write correct concurrent and parallel systems. Grain abstraction, which provides a straightforward approach to building distributed interactive applications, without the need to learn complex programming patterns for handling concurrency, fault tolerance, and resource management. This allows Proto.Actor to leverage in-process performance for realtime stream processing.

The map type in Go doesn't support concurrent reads and writes. concurrent-map provides a high-performance solution to this by sharding the map with minimal time spent waiting for locks. Prior to Go 1.9, there was no concurrent map implementation in the stdlib. In Go 1.9, sync.Map was introduced. The new sync.Map has a few key differences from this map. The stdlib sync.Map is designed for append-only scenarios. So if you want to use the map for something more like in-memory db, you might...

A Golang lock-free thread-safe HashMap optimized for fastest read access. It is not a general-use HashMap and currently has slow write performance for write-heavy use. The minimal supported Golang version is 1.19 as it makes use of Generics and the new atomic package helpers. Reading from the hash map for numeric key types in a thread-safe way is faster than reading from a standard Golang map in an unsafe way and four times faster than Golang's sync.Map.

Pool is a thread-safe connection pool for net.Conn interface. It can be used to manage and reuse connections. Use pool as the package name inside the code.
