binlog_zstd_comp_decompress.test

# === Purpose ===
#
# Verify ZSTD binary log compression memory performance schema counters.
#
# === Requirements ===
#
# R1. Performance schema counters must monitor binlog compression and decompression memory usage.
#
# === Implementation ===
#
# 1. All pfs are initalized when Performance_schema_memory_classes_lost is zero
# 2. memory/sql/Rpl_thd_context pfs is defined
# 3. memory/sql/Mts_submode_database::set_multi_threaded_applier_context pfs is defined
# 4. memory/sql/Binlog_recovery::recover pfs is defined
# 5. memory/sql/show_binlog_events pfs is defined
#
# === References ===
# 
# Bug#35290223 Memory used by binlog compression is not instrumented
