Refine TTL support for string type(key-value) to reduce compaction read bandwidth

1

## Description Disk read IO bandwidth is high even with blob db enabled(KV separation feature for RocksDB). ## Expected Behavior Avoid using value to store TTL, then avoid the high...

Avoid reading non-meta keys to invoke compaction_filter during compaction

1

## Description Tendis saves data's TTL in the value of RT_DATA_META-type keys ONLY . And it utilizes the RocksDB's compaction_filter to read TTL out of value and then checks whether...

When enabled RocksDB's blob_db support, non-blob key could be lost randomly

2

## Description When `rocks.enable_blob_files` is enabled, non-blob key could be gone randomly, either before TTL reached or no TTL is set at all. ## Expected Behavior Keys with TTL must...

## Description When blobdb enabled, avoid consuming read disk bandwidth by just checking keys of RT_DATA_META type. It solves #234 ## Motivation and Context The read bandwidth is too high...

Fix the issue #230, non-blob keys are dropped by compaction_filter incorrectly, resulting in data loss. ## Description - Provided a patch - Updated theCMakeLists.txt to apply the patch. ## Motivation...
