You need to ad If your workload involves frequent small transactions or queries that frequently request timestamps, [TSO (Timestamp Oracle)](/glossary.md#timestamp-oracle-tso) can become a performance bottleneck. To check if TSO wait time is impacting your system, check the [**Performance Overview > SQL Execute Time Overview**](/grafana-performance-overview-dashboard.md#sql-execute-time-overview) panel. If TSO wait time constitutes a large portion of your SQL execution time, consider the following optimizations: - Use low-precision TSO (enable [`tidb_low_resolution_tso`](/system-variables.md#tidb_low_resolution_tso)) for read operations that do not need strict consistency. For more information, see [Solution 1: use low-precision TSO](#solution-1-low-precision-tso). -- Enable [`tidb_enable_batch_dml`](/system-variables.md#tidb_enable_batch_dml) to reduce TSO requests for batch operations - Combine small transactions into larger ones where possible. For more information, see [Solution 2: parallel mode for TSO requests](#solution-2-parallel-mode-for-tso-requests). #### Solution 1: low-precision TSO From 3912e15364ef2e10ac0e623e2c0e55953aeb3007 Mon Sep 17 00:00:00 2001 From: Ti Chi Robot Date: Tue, 10 Dec 2024 11:52:06 +0800 Subject: [PATCH 2/2] OWNERS: Auto Sync OWNERS files from community membership (#19613) --- OWNERS | 20 -------------------- 1 file changed, 20 deletions(-) diff --git a/OWNERS b/OWNERS index 6b9b126ae31bc..d8624d0385098 100644 --- a/OWNERS +++ b/OWNERS @@ -12,26 +12,6 @@ approvers: - overvenus - qiancai - tangenta -emeritus_approvers: - - CaitinChen - - CharLotteiu - - cofyc - - DanielZhangQD - - dcalvin - - dragonly - - en-jin19 - - lichunzhu - - Liuxiaozhen12 - - morgo - - queenypingcap - - ran-huang - - shichun-0415 - - SunRunAway - - TomShawn - - toutdesuite - - WangXiangUSTC - - yikeke - - YiniXu9506 reviewers: - 3pointer - amyangfei
